Mag-Calcium Brick

Magnesia Calcium Brick (Magnesia Dolomite Brick)

　　Magnesia-Calcium bricks are made of high-purity and dense magnesia sand and dolomite sand as raw materials.According to different usage environments,suitable magnesium and calcium ratios are designed,using anhydrous binders,formed at appropriate temperatures and sintered at high temperature.Magnesia-calcium bricks are resistant to refining slag outside the furnace with low iron and low alkalinity and have good high-temperature performance.They also have the functions of desulfurization,dephosphorization,removal of impurities in steel and purification of molten steel.Products are widely used in smelting stainless steel AOD,VOD,GOR,LF-VD and other refining devices.
