Hydrated Lime, also known as calcium hydroxide and traditionally called slaked lime is an inorganic compound. Its molecular formula is Ca(OH)2 and its CAS is . Unprotected exposure to pure concentrations of hydrated lime can cause severe chemical burns. Diluted solutions such as limewater (calcium dihydroxide slaked with water) are used in food preparation.
steel steel Electricarc steelmaking: About onequarter of the world's steel is produced by the electricarc method, which uses highcurrent electric arcs to melt steel scrap and convert it into liquid steel of a specified chemical composition and temperature. External arc heating permits better thermal control than does the basic oxygen process, in which heating is accomplished by the ...
Our calcium and magnesiumbased products and minerals are used throughout the iron and steelmaking process as binders or flux agents to form slag. Slag removes harmful impurities, such as silica, phosphorus and sulfur. Lhoist products also help improve productivity and enable you to comply more readily with environmental legislation.
With the use of a good quality calcined lime, it is promising to reduce the lime usage in the converter and thus to have better mechanism of slag and temperatures in the converter. It also assists in increasing the yield of the liquid steel in the converter. Related products : hydrated lime, quicklime Highlight news about steel making

Raw materials Steel production. Coke. Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The coking coal is crushed and washed. It is then 'purified' or 'carbonised' in a series of coke ovens, known as batteries, where the coking coal is heated to ºC in the absence of oxygen for 1236 hours.
Basic oxygen steelmaking (BOS, BOP, BOF, or OSM), also known as LinzDonawitz steelmaking or the oxygen converter process is a method of primary steelmaking in which carbonrich molten pig iron is made into oxygen through molten pig iron lowers the carbon content of the alloy and changes it into lowcarbon process is known as basic because fluxes of burnt lime or ...

A lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime called quicklime (calcium oxide).The chemical equation for this reaction is . CaCO 3 + heat → CaO + CO 2. This reaction can take place at anywhere above 840 °C (1544 °F), but is generally considered to occur at 900 °C(1655 °F) (at which temperature the partial pressure of CO 2 is 1 ...
At the same time material will go ahead evenly inside kiln with even heating, so the quality of production is stable and crude burning rate and overburning rate is very low thus it could calcine high activity lime for steelmaking. Under the same condition, lime activity produced by rotary kiln which could be 340380ml or even 400ml is over ...
In this paper, we establish the feasibility of forming a reducible CaFe 3 O 5 (CWF) phase through the addition of lime to magnetite that can be directly charged to ironmaking units.
