Refractory Ramming Material

Unshaped refractory material is made by the refractory material as aggregate and powder with binder and admixture. The main products are refractory cement, refractory castable, refractory plastic material, refractory ramming material, refractory coating, gunning materials, and prefabricated parts. It is of excellent stability of thermal shocking and good workability, meanwhile it can be used in complicate hot-work equipment. It is widely used in catalytic cracking equipment of petrochemical industry, large generator, large-cement rotary kiln, middle and small blast furnaces, reheating furnaces, the iron notch of blast furnace, and hot-work equipment.
