Refractories dolomite is one of the important raw materials of basic refractories. Its importance is second only to magnesite. It is mainly used for steelmaking converter lining, open hearth furnace, electric furnace wall, followed by external refining equipment and cement kiln. And other thermal equipment. Dolomite can be made into dolomite brick series (mainly conventional dolomite brick, zirconium reinforced dolomite brick, zirconium reinforced magnesia dolomite brick, etc.), fused dolomite carbon brick and fused magnesia dolomite carbon brick.

Dolomite powder (snow white) 325 mesh can also be used as plugging material for blast furnace. It is reported that dolomite with raw ore size of 0-30mm is directly used as hot metal plugging material in WISCO. If the white dolomite powder is used as the material to block the hot metal hole in the steel-making blast furnace, the effect is better than using it directly as the material to block the hot metal hole.
