Production process:


The production methods of high heat Alumina Checker Brick​ ​​and clay bricks are basically the same.

 

Only some process parameters are different. There are also processes such as crushing → mixing → molding → drying → firing → inspection → packaging.

 

The compressive stress is better at low temperature, but slightly reduced at high temperature, so the stack in the kiln is less than 1 meter. The production process of high-alumina refractory bricks and multi-clinker clay bricks is similar.

 

The difference is that the proportion of clinker in the ingredients is higher, which can be as high as 90%-9%. The clinker needs to be sorted and sieved before crushing. The firing temperature is higher. For example, high heat Alumina Checker Brick such as Ⅰ and Ⅱ are generally 1500~1600℃ when fired in tunnel kiln.


Production practice proves that high heat Alumina Checker Brick is strictly selected and classified before crushing, and is stored in tiers. The co-fine grinding method of bauxite clinker and combined clay can improve the quality of high heat Alumina Checker Brick.

 

Aluminum oxide (Al2O3) content is higher than 48% high heat Alumina Checker Brick

A neutral refractory with an alumina content of more than 48%.Made of bauxite or other raw materials of high alumina content after molding and calcining.High thermal stability, refractoriness in 1770℃ above.Good slag resistance, used for lining steelmaking electric furnace, glass furnace, cement converter, etc.
