Ferrous Metallurgy

Gurmed insulating castables are used to line the outer middle section of modern blast furnaces also, the uptake sections of the top of the blast furnace are lined with gunned insulating material. [Pg.44]

The blast furnace stove, which heats the air that will be blown into the furnace from the tuyeres and burns the coke, is insulated with an acid-resistant gurmed material. The stack section is also lined with a gunned castable. A high-alumina monolithic refractory is used around the spout of the torpedo ladle. Torpedo ladles are used for transferring molten iron from the iron-making section of the plant to the steel section. Often when shortterm repairs are done to this item, monolithic refractories are used. [Pg.44]

In steel plants, monolithic refractories are used in sections of the linings of teeming ladles, converters, molten steel ladles, vacuum degassers, and tundishes. In tundishes, the majority of refractory lining is made from [Pg.44]


Approximately 200 large enterprises are operating in ferrous and non-ferrous metallurgy, pipe and rolling industry. These include the world largest complexes for the production of cast iron, steel, rolled stock and pipes in Dniepropetrovsk, Zaporozhje, Donetsk, Makeevka, Mariupol and other cities. [Pg.966]

The estimated world production of tellurium from 1991—1994 is shown in Table 4 the average annual production in that time period was 240 tonnes. The data for 1994 are considered to be the most accurate because of the direct reporting, for the first time, of production from plants in the former Soviet Union. The main uses for tellurium are as a free machining additive in ferrous metallurgy (55%), as a free machining additive in nonferrous metallurgy (10%), in chemicals (30%), in electrical appHcations such as solar cells and thermoelectrics (3%), and miscellaneous (2%). [Pg.387]

An alternative commercial form of a metallic mixed lanthanide-containing material is rare-earth siUcide [68476-89-1/, produced in a submerged electric-arc furnace by the direct reduction of ore concentrate, bastnasite, iron ore, and quart2. The resulting alloy is approximately 1/3 mischmetal, 1/3 sihcon, and 1/3 iron. In addition there are some ferro-alloys, such as magnesium—ferrosilicons, derived from cerium concentrate, that contain a few percent of cerium. The consumption of metallic cerium is overwhelmingly in the mixed lanthanide form in ferrous metallurgy. [Pg.368]

The purity of the cerium-containing materials depends on the appHcation as indicated in Table 3, and purity can mean not only percentage of cerium content but also absence of unwanted components. For some uses, eg, gasoline production catalysts, the lanthanides are often used in the natural-ratio without separation and source Hterature for these appHcations often does not explicitly mention cerium. Conversely, particulady in ferrous metallurgy, cerium is often assumed to be synonymous with rare-earth or lanthanide and these terms are used somewhat interchangeably. [Pg.369]

No single volume could contain the complete description of the composition, properties, and structures of ferrous alloys. Further, the effect of heat treatment and other methods of changing the properties of alloys constitutes an entire science unto itself. Accordingly, the description given of ferrous metallurgy will be only an overview of this enormously important area. [Pg.378]

There is a great number of dioxin-hazardous chemical enterprises, non-ferrous metallurgy plants, and works engaged in thermal treatment of industrial and domestic wastes, on the territory of Ukraine. Taking this fact into consideration, a threat of polluting the objects of the environment with dioxins exists. [Pg.91]

Calcium fluoride occurs in nature as the mineral fluorspar or fluorite. It is used as a flux in ferrous metallurgy to enhance the fluidity of the slag. An important application of this compound is in the manufacture of fluorine and hydrofluoric acid, starting materials for producing many fluoroorganics. It also is used in glass and ceramics. Pure crystals are used in lasers, optics, and electronics. Other applications are in high temperature, dry-film lubricants ... [Pg.164]

Space will not be devoted here to emphasis of the vast technological importance of iron and the steels nor to the discussion of ferrous metallurgy. However, typical processes for obtaining cobalt and nickel from natural sources are outlined in Table 24-1. The process for cobalt is somewhat oversimplified, for cobalt ores often contain, in addition to iron and arsenic, nickel, silver, or copper, which must also be removed. Note that nickel is conveniently purified by conversion to its volatile carbonyl, Ni(CO)4, unstable at high temperatures Mond process). [Pg.393]

Applications of atomic absorption spectrometry in ferrous metallurgy... [Pg.211]

Atomic absorption spectrometry was introduced approximately 18 years ago into laboratories concerned with the analysis of materials connected with ferrous metallurgy. Thus, literature references for this area of analysis only cover this period [89, 103, 134, 135, 151, 154]. Atomic absorption apparatus has been improved significantly during the past decade. Analysts have made demands upon manufacturers which have led to the development of sophisticated electronics and improvements in optical systems [33, 34,52, 53,59,148,149]. [Pg.211]

Table 1 summarises the most common materials in ferrous metallurgy, listed by element, which are analysed by atomic absorption spectrometry. [Pg.213]

By means of the microprocessors built into recent instruments, operations such as calibration and checking of stability have been simplified. The analyst needs only to use universally accepted standard methods which can be easily applied to as many classes of materials as possible. Such methods will be described in the following sections for chemical analysis in the ferrous metallurgy industry. [Pg.213]

Analysis by AAS of (most) trace elements in bulk materials from the field of ferrous metallurgy is still in its early stages. [Pg.234]

In the analytical procedures of ferrous metallurgy calibration methods have quickly proved useful, interferences being compensated for from the outset although they are not known individually. [Pg.242]
