Fused cast skid rail block

Introduction:

Zircon-mullite fused cast block is a fused cast refractory product made of mullite and zircon, mainly used for parts that require wear-resistant, high-temperature resistant materials, usually used as skid rail block, also named fused cast skid rail block.

Advantages:

Compact crystal structure, high refractoriness under load, good thermal stability, high mechanical strength, good wear-resistance, good thermal conductivity, excellent resistance to slag erosion

Application:

Metallurgical reheating furnace, soaking furnace, discharge port of calcium carbide furnace, wall of glass melting furnace/kiln
