Magnesia Hercynite Brick

Introduction

Magnesia hercynite brick is a basic refractory brick working in cement rotary kiln, the key difference between it and traditional spinel brick lies in its excellent kiln coating capability. This brick is environment friendly product without chrome be concluded and have better toughness than magnesia chrome brick.

Characteristic

1. Good thermal shock resistance
2. Excellent toughness
3. Well corrosion resistance
4. High slag penetration resistance
