High-strength mullite castable with high temperature, can be used as working lining in direct contact with flame to achieve high temperature energy saving;

The product has two types of heavy and light weight, light weight products, light weight, structure weight reduction of 40 ~ 60%, eliminate the occurrence of the furnace roof hanging brick broken brick;

Low thermal conductivity, high strength porous mullite aggregate ingredients, low thermal conductivity, good insulation performance;

Can be quickly oven, shorten the oven duration;

High-strength mullite castable is suitable for petrochemical industrial tubular heating furnace, light diesel oil, ethane cracking furnace lining, atmospheric and vacuum furnace, sulfur recovery device, steam boiler, tortoise shell net insulation layer, two cylinder and pipeline insulation single layer, other industrial furnace furnace door, fire hole, observation hole door lining, etc.
