Metallurgy in Eurasia originated in Southwest Asia due to the widespread adoption of, and experimentation in, pyrotechnology and the desire for new materials to serve as aesthetic visual displays of identity, whether of a social, cultural or ideological nature. This can be demonstrated through the early use of metal for jewellery and the use of ore-based pigments along with the continued use of stone, bone, and other materials for most tools. The subsequent appearance of metals throughout Eurasia is due to the acquisition of metal objects by individuals and communities re-inventing traditions of adornment, even in regions hundreds of kilometres from the nearest sources of native metals or ores. The movement of communities possessing metallurgical expertise to new ore sources and into supportive societies led to the gradual transmission of metallurgy across the Eurasian landmass. By the second millennium BC, metallurgy had spread across Eurasia, becoming firmly rooted in virtually all inhabitable ...

The blast furnace slag and the wet or dry charge may be injected into the feed end of the rotary kiln as separate materials or may be injected together without premixing at the feed end of the kiln.. Fifth, only slight chemical composition changes in the feedstock composition are required for normal feedstock to accommodate the blast furnace slag. This usually means that the lime content of the charge must be richer.. Sixth, the coarse blast furnace slag chemistry is transformed into the desired cement clinker structure during heat treatment in a rotary kiln by diffusion.. Seventh, significant energy savings are realized when the blast furnace slag is used because the blast furnace slag melts at low temperatures and does not require any grinding or milling of the blast furnace slag.. Eighth, the increase in cement clinker formation is almost proportional to the amount of blast furnace slag used.. Ninth, the environmental conditions of the rotary kiln process are improved due to the low volatile ...

The aim of this study was to assess the environmental effects of Moshyttan, one of the earliest known blast furnaces in Europe (ca. 11th century). The study was based on the analysis of three lake records in the immediate surroundings of the smelter. Fickeln lies directly downstream and is the main recipient of waterborne pollution. Mosjökälla lies directly upstream and served as the main water reservoir for the water-powered bellows. Kramptjärnen lies 1 km to the NW in a separate catchment and acts as a reference. The data includes 31 elements analyzed by X-ray fluorescence spectroscopy (XRF), organic content inferred from loss on ignition (LOI), biogenic silica (BSi) modeled from Fourier-transform infrared spectroscopy (FT-IRS) for all lakes and diatom counts for Fickeln. Two other studies provided dating of slag from the smelter and pollen- and geochemical data from Fickeln. The results show that the metallurgy and associated activities (e.g. agriculture, forest grazing and charcoal ...

TY - JOUR. T1 - A comparative study of pellets, sinter and mixed ferrous burden behaviour under simulated blast furnace conditions. AU - Gavel, Dharm Jeet. AU - Adema, Allert. AU - van der Stel, Jan. AU - Peeters, Tim. AU - Sietsma, Jilt. AU - Boom, Rob. AU - Yang, Yongxiang. PY - 2020. Y1 - 2020. N2 - Physicochemical behaviour of the pellets, sinters and its mixture (60% pellets: 40% sinter) is investigated by a series of smelting and quenching experiments. For all ferrous raw-material beds, three distinct stages of bed shrinkage occur due to indirect reduction, softening and melting. However, the characteristic nature (displacement, temperature and permeability) differ with the ferrous raw-material type. In mixed ferrous bed, the first and third stages are found to be controlled by the pellets (individual particle shrinkage) and sinter (slow melting rate), respectively. Second stage behaviour is initially observed to be close to the pellet and later to that of sinter. In mixed bed (upto ...

Despite their excellent balance of properties, titanium alloys are still a niche material whose range of applications is limited by the high cost of their manufacturing. With recent developments, powder metallurgy (PM) approaches, in particular the blended elemental (BE) route, are able to reduce considerably the cost of manufacturing while keeping a reasonable performance, mostly in terms of tensile strength and ductility. The cost reduction of the BE approach derives from the simplification of the process by removing a large amount of re-melting and ingot breakdown operations, regardless of the use of the approach as a net-shape technology. However, in terms of fatigue behaviour, the performance of these alloys is generally worse than conventional processes unless additional steps are applied. This thesis aims to study the mechanical behaviour, with emphasis on the fatigue behaviour, of two cost-effective titanium alloys in order to find the key processing, microstructural and texture ...

The steel powder compacts exhibited an unusual combination of strength and ductility in every state of heat-treatment which was employed, The numerical values of the tensile properties were lower than those obtained from wought material of similar composition but considerably higher than anay which have previously been obtained for powder compacts. The hardness of the heat-treated powder compacts tempered after quenching was lower than that of the corresponding wrought bars. The resistance of the powder compacts to impact (as measured by tests on snall un-notched bars) was lower than that of wrought bars of corresponding size but higher than that which would normally be expected of powder material of such high strength characteristics. The elastic modulus of thesteel powder compacts was approximately the same (30,000,000 p.s.i.) as that of wrought steel bars, This is regarded as being unusual for powder metal material.DUCTILITY

Pressure powder metallurgy process for consolidating refractory or rhenium alloys using a reduced temperature and elevated pressure. Rhenium metal has high temperature strength and wear resistance but has a very high melting point as a pure metal and thus is difficult to use as a coating for many alloys having lower melting points. The reduced temperature and elevated pressure alloying process of the rhenium allows it to be used as a coating for other metal alloys, such as nickel and steel alloys, providing some high temperature and wear resistance due to the properties of the rhenium material in the coating.

The main finding of this study was that exhaled NO concentrations in non-smoking potroom workers were 63% higher than in non-smoking control subjects recruited from the same plant. The two groups were otherwise comparable for occurrence of asthma-like symptoms and use of β2-agonists. No subject in either group used corticosteroids. The potroom workers were somewhat younger than the controls (mean age 40 v 46 years), but concentrations of exhaled NO have not been shown to vary with age.12 Although the exhaled NO concentration in the non-smoking potroom workers was not as high as that found in symptomatic asthmatic subjects, it was comparable to the concentration observed in atopic subjects with bronchial hyperresponsiveness.18 In smokers, we found no difference in exhaled NO between potroom workers and controls. This may be because chronic cigarette smoking itself decreases exhaled NO, both in healthy19 and in asthmatic subjects.20 In mildly asthmatic subjects, the effect of smoking on exhaled ...
OBJECTIVES: To determine whether occupational exposure to chromite, trivalent chromium, or hexavalent chromium causes respiratory diseases, an excess of respiratory symptoms, a decrease in pulmonary function, or signs of pneumoconiosis among workers in an integrated chain of stainless steel production. METHODS: This cross sectional study was carried out in 1993 and the inclusion criterion was a minimum of eight years of employment in the same production department. A self administered questionnaire was collected, and spirometry, measurement of diffusing capacity, chest radiography, and laboratory tests were carried out by a mobile research unit. RESULTS: There were 221 workers in the exposure groups and 95 in the control group. The average duration of employment was 18 years. No significant differences in the odds ratios (ORs) of the symptoms were found between the exposure and the control groups. In a logistic regression analysis age and smoking significantly explained the occurrence of most of ...

By Dr. Michael Berg, EMLab P&K Senior Molecular Biologist. Metalworking fluids (MWFs) are used in industrial machining and grinding operations to reduce heat and friction and to improve product quality. They are categorized into straight or neat oils, soluble oils, semi-synthetic and synthetic fluids. Generally, MWFs are complex mixtures containing a number of additives to improve performance and stability including emulsifiers, anti-weld agents, corrosion inhibitors, extreme pressure additives, buffers, dyes, odorants and biocides. In use, the fluid complexity is compounded by contamination with substances from the manufacturing process such as tramp oils, hydraulic fluids and particulates from grinding or machine operations. Furthermore, water-based MWFs may support microbial growth adding biological contaminants in the form of bacterial and fungal cells and their related byproducts such as endotoxins, exotoxins and mycotoxins. Each component of the complex mixture can contribute to health ...
Occupational exposure to nickel occurs mainly through inhalation of dust particles and fumes or through skin contact. Acute exposure to high levels of nickel by inhalation can cause severe damage to the lungs and kidneys. Prolonged exposure to nickel refinery dust among nickel refinery workers leads to an increased risk of lung and nasal cancers. Nickel refinery dust is a mixture including many nickel compounds as well as other inorganic substances. Nickel subsulfide is the major constituent in refinery dust from the smelting of sulfidic ores. Chronic dermal exposure to nickel can lead to dermatitis with complaints such as dry, irritated or itchy skin. Chronic inhalation exposure to metallic nickel and water-insoluble nickel compounds can result in respiratory effects, including decreased lung function and bronchitis. Chronic exposure to soluble nickel compounds by inhalation can also result in asthma cases.. Latency period between exposure and nickel related cancer varies from 13 to 24 ...

The Department of Mining Engineering had its conception in the 1867 aims of the Illinois Industrial Universitys Committee on Courses and Faculty, which listed the department as part of the proposed Polytechnic Department. Courses in mining engineering were offered in the Civil Engineering Department during the 1870-75 period. In 1885, the University faculty adopted and approved a B.S. program. The program had its first graduate in June 1887. With little student interest, the program lapsed in 1889. An attempt was made two years later to revive interest by offering a course for coal miners. A lack of response caused the Department to be abolished in 1891. In 1901, the Board requested Illinois members of Congress to support a bill promoting mining engineering. In June, 1909, the Illinois General Assembly passed an act calling for a Department of Mining Engineering with provision for instruction and extension work by the University. In 1911, the Department began to work closely with the State ...

The main target includes the ridge where steeply dipping Ordovician age quartzite is exposed over a strike length of approximately 850 meters. Geological mapping, geochemical sampling, and surveying identified a series of white quartzite outcroppings (Wonah Quartzite Formation) that form 2 lenses, the Central Zone that has been traced for approximately 500 m, and South Zone traced for 350 m along strike. The Central and South Zones consist of a highly competent quartzite unit that trends N to NNE, is approximately 50 meters in width, and has a steep east dip. There is an ESE trending fault between the Central and South Quartzite Zones that has an approximate 200 m sinstral, horizontal displacement. A total of 11 rock chip quartzite samples were taken from the Central & South Zones by MGX VP Exploration Andris Kikauka (P. Geo.) shortly after acquisition in 2015.

Tartaglia proceeded by cutting the trajectory of the cannonballs into different portions and then identifying them with the two different sorts of motion his conceptual apparatus was able to provide. The theory of ballistics that emerged from this operation was basically an analysis of the portion of the trajectory that was associated with violent motion. On the basis of this procedure, Tartaglia was able to draw quantitative consequences not only concerning the maximal range, but also concerning the variation in the destructive power of cannon shots in dependence on the distance between target and cannon, and on the elevation of the artillery.. The tests executed by means of cannons, around which Tartaglia narrates in his work, merely symbolize the background against which the new science of ballistics emerged. Clearly, and as it has already been stated by several scholars, the background knowledge involved in the process of emergence of the theoretical ballistics was represented by the ...

So one of the unions representing refinery workers wants to make safety improvements part of its latest round of contract talks.. At noon today, Bay Area members of the United Steelworkers plan to rally at Chevrons headquarters in San Ramon. Their union is in the midst of contract talks with multiple oil companies - not just Chevron - and wants its workers to have a bigger role in how refineries enforce safety rules.. People who work in oil refineries are eight times more likely to die on the job than in any other type of manufacturing in the nation, said Jeff Clark, secretary treasurer of United Steelworkers Local 5. That needs to improve.. Local 5 represents about 1,500 employees of Bay Area refineries, including Chevrons Richmond refinery.. Chevron, for its part, says its willing to talk safety, although a company spokesman declined to get too specific..

Metalworking fluids (MWFs) are used to reduce heat and friction and to remove metal particles in industrial machining and grinding operations. There are numerous formulations, ranging from straight oils (such as petroleum oils) to water-based fluids, which include soluble oils and semisynthetic/synthetic fluids.

* Mining law aims to force miners to process minerals athome* Copper producers Freeport and Newmont in dispute with govt* Clock winding down before concentrate exports due to stopcompletely* Firms planning smelters say need firm supply commitmentsfrom minersBy Michael Taylor and Wilda AsmariniJAKARTA, Feb 24 (Reuters) - Indonesian policies to forceminers to process raw materials at home are misfiring, asdisputes over the new rules disrupt plans to invest nearly $4billion in copper smelters to cater for miners such asFreeport-McMoRan Copper & Gold.President Susilo Bambang Yudhoyono imposed a controversialmining law on Jan. 12, but the rules have left the mining sectorin turmoil. As well as a ban on unprocessed ore shipments, alast-minute export tax on concentrates was also brought in.The tax ratchets up sharply before an outright export banfrom 2017 and Freeport and Newmont Mining Corp, whichproduce 97 percent of Indonesias copper, have halted allexports and are locked in talks with the government
(PhysOrg.com) -- A barrier coating developed through CSIROs Light Metals Flagship offers aluminium smelters significant annual savings in reduced consumption of petroleum coke alone.
Sinter and geyserite, formed largely of amorphous opaline silica (opal-A), precipitate at many hot-spring and geyser systems like those found on the North Island of New Zealand. Opal-A is a hydrated silicon dioxide (SiO2.n H2O) that may contain silanols, trapped water, and/or absorbed water. Little is known about the factors that control the distribution of water (H2O + OH) in sinter and geyserite.. Backscattered electron images (BSEI) of geyserite and sinter commonly reveal sectors and/or alternating laminae that are characterized by differences in their average atomic weights. Electron microprobe (EMP) and scanning electron microscope (SEM) analyses, however, show that differences in the average atomic weights cannot be attributed to the presence of other elements (e.g., Au, Ag) or minerals (e.g., sulfur, kaolinite, jarosite). The compositional heterogeneity in the opal-A, as highlighted by BSEI, must reflect variation in the water content of the opal-A. Integration of BSEI and EMP analyses ...
Welcome to the International Titanium Association The International Titanium Association (ITA) is a membership based international trade association dedicated to the titanium metal industry. Established in 1984, the ITAs main mission is to connect the public interested in using titanium with specialists from across the globe who may offer sales and technical assistance. Working through our extensive membership resources, we seek to expand the knowledge base for the metal, providing technical literature and sponsoring seminars and conferences.
