Application Of Dolomite In Iron Making And Steel Making Processes
Raw dolomite is used in the size range of 4 mm to 8 mm. The second major use of dolomite is in steelmaking. In steelmaking dolomite is used both as a fluxing material and also as a refractory material. For use in steelmaking, the SiO2 (because of its acidic nature) content in the dolomite is to be very low preferably less than 1 %.

Dolomite – A Useful Mineral
Dolomite is grouped under flux and construction minerals, It has a number of applications. One of its large applications by volume is in construction where it may substitute for limestone. It is an important raw material for iron and steel, ferro-alloys, glass, fertilizer, and many more industries. Dolomite chips are also used in flooring tiles.
Dolomite in Steel Making
The addition of dolomite to the steel-making process also improves the fluidity and workability of molten steel. Dolomite acts as a desulfurizing and dephosphorizing agent, which helps to reduce the sulfur and phosphorus content in the steel. High levels of sulfur and phosphorus can cause brittleness in the steel, making it difficult to work with.
Lime, an essential component in the steel industry
Phosphorus removal: Phosphorus, contained in the iron ore and the scrap metal that are used to start the steel-making process, can seriously damage the properties of steel.In large quantities, it lowers the ductility of the steel making it easy to fracture when it is cold-worked. Quicklime added to the metal-making process extracts the phosphorus in the steel, lowering its proportion to …
