Line is a naturally occurring and abundant sedimentary rock consisting of high levels of calcium carbonate (CaCO3) in the form of the mineral calcite. Some lines may contain small percentage of magnesium carbonate.line iron industry,Line and dolomite flux and their use in iron and steel plant .May 8, 2013 . Hence it is necessary to know comprehensive information of the line such as physical and chemical properties. The major use of line in industry is shown in Fig.2. Industrial use of line.

Modern architecture would be inconceivable without steel. Cars need lightweight steel bodies with high mechanical strength. As a competent partner to the steel industry, we promote the further development of steel products meeting ever higher quality requirements. Lime is the purifying element in iron and steel production,.

Steel is one of the biggest drivers of the world economy as it plays a major role not only in the construction and automotive industries, but also in mechanical engineering applications. Global production in 2012 was approximately 1.55 billion tons, worth about US$1,000 billion. Every ton of steel requires 30 to 70kg of lime.

Although this imported material is substantially more expensive than dolomitic lime, some steel companies considered using it because of claims that it dissolved more quickly, and thus improved performance. However, studies have shown that this imported magnesite does not in fact go into solution more quickly than MgO.
A steel mill or steelworks is an industrial plant for the manufacture of steel. It may be an integrated steel works carrying out all steps of steelmaking from smelting iron ore to rolled product, but may also describe plants where steel semi-finished casting products (blooms, ingots, slabs, billets) are made, from molten pig iron or.
Sinter is made of lesser grade, finely divided iron ore which, is roasted with coke and lime to remove a large amount of the impurities in the ore. Line occurs naturally and is a source of calcium carbonate. Other metals are sometimes mixed with iron in the production of various forms of steel, such as chromium, nickel,.
The blast furnace uses either high-grade iron ore or the iron ore pellets together with coke and line. In a modern blast furnace, the mass of each component and the timing of its addition to the furnace are computer-controlled, responding automatically to the conditions prevailing at that time in the furnace.
type of very fine-grained line. Most lime- stones contain varying amounts of impurities in the form of sand, clay and iron-bearing materi- als. These impurities are usually present in very small proportions in industrial lines, which are generally valued for their high chemical puri- ty (generally >97% CaCO3).
May 2, 2010 . HIGHLIGHTS. ▫ PROCESSES AND TECHNOLOGY STATUS – The basic materials for iron production are iron ore, coal and coke (also used as energy input to the process) or alternative reducing agents, line and dolomite. Steel production requires iron, steel scrap and lime (burnt line).

220.127.116.11 Sinter Production -. The sintering process converts fine-sized raw materials, including iron ore, coke breeze, line, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charging into the blast furnace. The raw materials are sometimes mixed with water to provide a cohesive matrix.
Iron Industry Background. In order to smelt iron three materials are required: a fuel source, iron ore and a “flux” which aids in separating metallic iron from impurities in the ore. Line is one of the best fluxes. The Lehigh Valley has all three; in quantity! Just north of the Lehigh Valley, along the Lehigh River, lie immense.
iron and steel industry - Flux and slag - The line in the furnace fluxes, or purifies, the iron. It helps some of the impurities in ore and coke to fuse, or melt. The line then combines with some of the melted impurities to form slag. The flux begins to melt below the halfway point in the furnace. Since the slag is lighter.
Like coal, mineral oil, and iron ore, line is one of the most important raw materials as can be seen from its wide range of applications: in the iron and steel industry, building materials and construction industries, chemical industry, and agriculture. Many products cannot be produced without line and also in terms.
Most of the two billion tonnes of lime- stone consumed annually is used either as the basic raw material in the manu- facture of cement or as flux input in the metallurgical industries. Of the total flux, 90% is used by the steel industry. The cement industry needs line in a finely pulverized form, whereas the steel industry.
Line is calcareous sedimentary rock composed of mineral calcite (CaCO3) which upon calcination yields lime (CaO) for commercial use. Cement and Iron & Steel are the major consumers of line. It is also consumed in chemical industries like calcium carbide, bleaching powder, soda-ash, precipitated calcium.
Jun 15, 2010 . At Longview the Madaras Steel Corporation built a pilot plant in 1941 to reduce iron ore to sponge iron by a process, invented by Julius D. Madaras of Detroit, that eliminated the pig-iron stage and used cracked natural gas instead of coke and line. Sponge iron in lump or granular form was converted.
Among the many uses of lime in the steel industry, three stand out:
