Magnesia Ramming Mass

Magnesia ramming material is an alkaline amorphous refractory material made of high-purity fused magnesia/sintered magnesia as raw material, plus ultra-fine powder and additives. It has corrosion resistance, erosion resistance, good volume stability, load softening High temperature, convenient construction, etc., and is mainly used for new lining, repair, and caulking of iron and steel metallurgical furnaces.
