Reheating furnace Refractories Generality High Alumina Brick & Clay Brick

Introduction:

Clay brick refers to a clay product with an Al2O3 content of 30% to 40% aluminum silicate. Clay bricks are used in secondary parts of coke ovens, such as regenerator wall sealing, small flue lining bricks and regenerator grid bricks, furnace door lining bricks, furnace roofs and riser lining bricks. 

 

Advantages:

Clay bricks are weakly acidic refractory products, which are resistant to the attack of acid slag and acid gas. The clay bricks have good thermal properties and are resistant to rapid cooling and rapid heat.

Introduction:
High alumina bricks are refractory products of aluminum silicate or alumina with Al2O3 content greater than 48%. High alumina bricks are mainly used for laying blast furnaces, hot blast stoves, electric furnace tops, blast furnaces, reverberatory furnaces, and rotary kiln linings. 

Advantages:
The high alumina brick has high density, low porosity, high mechanical strength and wear resistance, high softness of load, and good slag resistance.
