We are a refractory material manufacturer, with four major factories: heavy brick factory, light brick factory, monolithic refractory factory and fused-cast brick factory.
We promise to provide you with high-quality refractory materials.
Lightweight clay insulation brick is made of clay as the main raw material and sintered by high temperature. The product has the advantages of high strength, good thermal shock stability, small change of re-firing line and small thermal conductivity, etc. It is mainly used for various kiln linings and insulation layers in metallurgy, machinery, ceramics, chemical industry, etc.
2. Application of insulation fire clay brick
Lightweight refractory insulating clay bricks are mainly used as thermal insulation lining for high temperature surfaces or insulation for other refractory materials. It is used for refractory lining or insulation of ethylene cracking furnace, tube furnace, ammonia conversion furnace, gas generator, high temperature clinker kiln and other industries.
3. Parameters of insulation fire clay brick
