Magnesia Ramming Mass
1.The magnesia ramming mass adopts high purity synthetic dolomite sand and high purity magnesia sand as the main raw materials, while adding a certain amount of binding agent, by mixing.
2.Its features are high density,high strength,good slag resistance,high corrosion resistance,high thermal resistance and volume stability.
3.It is widely used in ramming the furnace bottom of high power electric arc furnace,and ferro alloy electric arc furnace.
