LIME AND DOLOMITE FOR THE STEEL INDUSTRY
Dolomite is also needed to protect the refractory lining of the steel furnace or converter, increasing the life span – a crucial parameter from a financial viewpoint. SMA Mineral can supply both types of high quality alkaline flux, for every type of steel manu-facturer, including carbon steel producers and those that manufacture stainless steel.
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.
