Refractories 
Description:
Reburned magnesia sand is made by using natural magnesite and calcining it in a high-temperature vertical kiln.
Features:
The sintering degree of the calcined magnesia sand is good, the chemical composition is uniform, and the quality is stable.
Application:
It is an ideal raw material for manufacturing and producing amorphous refractory materials, and products are used for steelmaking, electric furnace bottoms, and ramming furnace linings.
