Product Overview

Where can i buy insulation refractory castable? And what is insulation refractory castable?

Henan is the most famous refractory raw material basis in China. SIJIHUO REFRACTORY has manufactured unshaped refractories for more than 20years. We can help to solve your problems of refractory castable.

Insulation castable is the widely used thermal insualtion refractory material for industrial furnace insulation linings. It's made of light weight refractory aggregates and fine powder, binders and additives. Refractory aggregate varies including high alumina, porus clay, hollow ball, expanded perlite, and mullite materials etc, which decided the different insulation castable chemical and physical properties.

Characters

  • Small volume density
  • low thermal conductivity
  • Good thermal insulating

Application

This kind of insulation castable is suitable for insulation linings of cement rotary kiln.

Professional Suggestions

As per different furnace lining design,  and client’s demand on insulation castable specification should also be adjusted. Bulk density varies from 0.5~1.8g/cm3, thermal conductivity will be changed accordingly.
