Magnesia calcium brick

Using high-purity and dense magnesia and sintered magnesia dolomite sand or dolomite sand as raw materials, according to different use environments, select the appropriate ratio of MgO and CaO, use anhydrous binder, mold at an appropriate temperature, and burn at high temperature. to make. The product has strong resistance to low iron and low alkalinity refining slag outside the furnace, and is beneficial to desulfurization and dephosphorization to remove impurities in steel, and has the effect of purifying molten steel. Used in cement kilns, magnesia-calcium bricks have a great affinity with cement clinker, are easy to hang on the kiln, and have uniform thickness. Magnesium-calcium products are suitable for stainless steel refining furnaces. For example, the AOD and VOD furnaces outside the furnace are used as substitutes for magnesia-chrome bricks in the firing zone of cement kilns, and their applications are becoming more and more extensive. And LF-VD ladle, etc. Electric furnace magnesia carbon brick
