Dolomite is one of the important raw materials of basic refractory. It is second to magnesite in importance. It is mainly used for lining, flat bottom furnace, electric furnace wall, and then for external refining equipment and cement kiln. Etc. thermal equipment. Dolomite can be made into dolomite brick series (mainly conventional dolomite brick, zirconium reinforced dolomite brick, zirconium reinforced dolomite brick, etc.), electric melting dolomite carbon brick and electric melting magnesium dolomite carbon brick.

Dolomite powder (snowflake white) 325 mesh can also be used as the plugging material of iron making blast furnace. It is reported that dolomite with the particle size of 0-30mm is directly used as the plugging material of blast furnace. If the white dolomite powder is used as the material to block the pore in the blast furnace, the effect is better than that of directly using it as the material for blocking the pore.
