Zirconium refractory concrete

Zirconium refractory concrete ramming mass is a kind of unshaped refractory material, which has the characteristics of high fluidity and easy operation.Zirconium refractory concrete is made of fused corundum aggregate particles and a small amount of additives.Zirconium refractory concrete has the advantages of easy to use, hardening at room temperature, high temperature resistance, high strength, low thermal expansion and shrinkage, strong corrosion resistance and so on.Zirconium refractory concrete ramming mass is made of high quality zirconium mullite sand, powder, aluminum phosphate as binder and additives, according to the best proportion of preparation.Zirconium refractory concrete ramming mass utility model has the advantages of low thermal conductivity at high temperature, good thermal shock resistance, chemical stability, good corrosion resistance to molten glass and liquid metal, stable operation under the oxidizing atmosphere, and no chemical reaction with molten metal.Zirconium refractory concrete is a kind of excellent refractory material.
