Product overview

Synthetic magnesia, high-iron and high-calcium sand, magnesia-aluminum spinel sand, magnesia dolomite sand. All kinds of synthetic spinel sand are made of high-quality magnesite, dolomite raw materials, iron powder bauxite, industrial alumina powder and other additives into balls and then fired at high temperature. This product uses high-purity raw materials and is formed by high pressure. , Calcined at high temperature. It is characterized by high density, high strength, and high corrosion resistance. It is an ideal raw material for the production of electric furnace bottom dry beaters and hot repair materials.
