magnesite chrome brick,
insulating refractory brick
Magnesium-calcium brick/Used for side - blowing converter, oxygen - blowing converter/Resistance to basic slag
Dolomitic sand, magnesia dolomitic sand and magnesia are used as raw materials, mixed with anhydrous binder, high-pressure forming and fired at high temperature.
Category of Refractory Brick/Fire Brick:
magnesium-calcium brick/Magnesium-dolomite brick
Magnesia dolomite brick and magnesia calcium brick main composition are MgO and CaO, just have a few distinction, magnesia calcium brick that magnesia dolomite brick is MgO content is tall, exceeded the magnesia calcium ratio of dolomite brick kind, dolomite brick is the brick that the magnesia calcium ratio in normal dolomite (1:1), main chemical composition is MgO and CaO are collectively referred to as magnesia calcium brick.
Magnesia dolomite brick is more stable than magnesia brick and magnesia chrome brick under vacuum, it has good high temperature performance, strong corrosion resistance, high softening temperature under load (above 1700℃), and has the function of purifying molten steel.Mainly used in stainless steel converter, smelting, AOD,VOD.
