Product Description:A castable mixture made of lightweight refractory aggregate with powder, binder and admixtures is called a light weight castable.
Product Features:Because of the small volume density and low thermal conductivity of light castable, it is also called light heat insulation refractory castable and light heat preservation refractory castable.
Application:Light weight castables are commonly used in the lining of furnaces, thermal equipment, smokestacks, smokestacks and smokestacks in metallurgical, mechanical, petrochemical, electrical, and building industries as thermal insulation, not in direct contact with flame.It can also be used as the working lining of various heating and heat treatment furnaces.
