Iron and Steel The National Lime Association

Quicklime both high calcium and dolomitic enjoys its most extensive use as a flux in purifying steel in the electric arc furnace (EAF) and basic oxygen furnace (BOF). Lime is particularly effective in removing phosphorus, sulfur, and silica, and, to a lesser extent, manganese. Lime also has important uses in secondary 

Limestone in industry Resources, conflicts and sustainability

Adding limestone also has the advantage of reducing the temperature required to melt the iron, so saving on energy. Although slag is a waste product of the iron and steel industry, it can be turned into 'slag cement' and used to make roads. Burnt lime made from calcite and dolomite is

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 for improved efficiency. In pellet plants, finelycrushed limestone and dolomite result in products with the desired basicity (ratio CaO + MgO vs.

Limestone and dolomite flux and their use in iron and steel plant

May 8, 2013 Both limestone and dolomite are extensively used in an iron and steel plant in various processes and their use is explained below. Specifiion of limestone and dolomite for iron making is less rigid. But for steel making limestone should have very low silica (SiO2) and alumina (Al2O3) since these 

How iron is made material, manufacture, making, history, used

The raw materials used to produce pig iron in a blast furnace are iron ore, coke, sinter, and limestone. Iron ores are mainly iron oxides and include magnetite, hematite, limonite, and many other rocks. The iron content of these ores ranges from 70% down to 20% or less. Coke is a substance made by heating coal until it
