Hot blast furnace use clayrefractory checker brick
1.Definition:
Clay brick is a kind of refractory material, which ismainly made of high grade chamotte clay and fire clay (soft clay orsemi-soft clay) binding agent, and Al2O3 Content range from30%~48%. It is widely used and largest output.
2.Properties:
1). High refractoriness under load feature.
2).Excellent resistant against middle temperature creepand thermal shock features.
3). Better high temperature bulk, creep and Abrasionresistant stability.
