Fire Clay Brick Introduction
Fireclay bricks refer to clay products with Al2O3 content of 30%~40%. The fire resistance can reach 1690~1730 ℃. Refractory clay brick is made of clinker clay through mixing, molding, drying, sintering and proportioning. It has good corrosion resistance, wear resistance, thermal shock resistance, spelling resistance, high mechanical strength, and good volume stability under high temperature.
Fire Clay Brick Features
1.Good resistance to corrosion and abrasion;
2.Perfect thermal shock resistance;
3.Good spalling resistance;
4.High mechanical strength;
5.Good volume stability under high temperature;
6.Excellent thermal performance, and acid resistance;
