It is made of natural magnesite and calcined by high temperature shaft kiln. It is the raw material for making bricks and producing unshaped refractory materials. The finished products are used for steel making, electric furnace bottom and ramming lining.
Dead-burned magnesium mainly consist of more than 46% of the content of magnesite stone, magnesite stone after high temperature shaft kiln calcined Mg when heated to 1400-1800 ℃ (CO3) complete decomposition, generate periclase, become hard reddish brown dead-burned magnesium, it has the very high refractoriness. It is the ideal raw material for producing refractory refractory materials, which are used in steelmaking, electric furnace bottom and ramming lining.
This kind of heavy - burning magnesium has high refractoriness. Its main components are magnesium oxide, which is made of natural super magnesite by flotation purification, light burning, fine grinding, high pressure ball, and ultra-high temperature oil shaft kiln.
