Insulating Fire Brick
The low creep high aluminum brick with mullite and andalusite as the main raw materials .Its formed by high pressure and fired at high temperature. It has the advantages of low impurity content, low porosity, small volume density, high temperature strength, stable volume under high temperature conditions, good thermal shock resistance and low creep rate. Suitable for large and medium-sized blast furnace supporting hot blast furnace.
▌FEATURES
1. Low creep rate；
2. High mechanical strength；
3. Good abrasive resistance；
