Fire Clay Brick

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.

Fire clay brick is made from clinker clay by mixing, forming, drying, sintering and matching characterized by good resistance to corrosion and abrasion, good thermal shock resistance, good spelling resistance, high mechanical strength, good volume stability under high temperature.
