Iron and steel making. Basically limestone is used as a slag former. Dolomite is used as a slag former, slag modifier and as a refractory material. The process of iron making is the reduction of iron ore to produce iron. Iron ore normally contain gangue materials such as silica (SiO2), Alumina (Al2O3) along with sulphur (S) and Phosphorus (P).
Limestone, sedimentary rock composed mainly of calcium carbonate, usually in the form of calcite or aragonite. It may contain considerable amounts of magnesium carbonate (dolomite) as well; minor constituents also commonly present include clay, iron carbonate, feldspar, pyrite, and quartz.
The basis of slag is limestone used as auxiliary material in the production of iron and steel. While limestone may seem unrelated to the production of iron and steel, it actually is an essential auxiliary material that is added during the production process.
Study on Accretion Formation on DRI kiln during spong iron production Chandrashekhar shrivas, Himanshu shrivas Abstract---Today is an era of competition, and contrary to this the Iron and steel industries are also suffering from the same.
