The body of the carbon rotary kiln is made of rolled steel plates, with refractory bricks and castable refractory lining built inside. The operating temperature ranges from 1200 to 1350 ° C. The commonly used refractory ca stables for the lining of the carbon rotary kiln include lightweight insulating ca stables , refractory cl ay castables, and high-alumina refractory castables, resulting in a composite lining that offers good integrity, high strength, and excellent wear resistance.
