Castable for carbon calcined rotary kiln has the advantages of high strength, high wear resistance, anti-flaking and anti-scouring. Castable for carbon calcined rotary kiln is suitable for rotary kiln kiln mouth, pre-tropical zone, calcination zone, cooling machine, feed nozzle and other parts.
Siliceous refractory repair material has high load-softening point, low temperature creep rate, high strength, low porosity, strong thermal shock resistance, anti-slag and anti-erosion, and will not damage the repaired structure due to expansionof quartz.
Electro-fused AZS refractory ramming mass is monolithic refractories and electro-fused AZS refractory ramming mix is composed of molten corundum aggregate particles and a small amount of additives.
