Premium Quality Alumina Refractory Bricks Chemical Attack To Provide Long Service Life

 

Description

 

The first-grade high-alumina brick (the aluminum content is not less than 75% refractory brick) is formed by pressing and calcining a high-quality raw material such as high-quality bauxite and alumina. The high-aluminum brick has a refractoriness of over 1790 °C. The load softening temperature is above 1510 °C, the thermal shock stability is good, and the slag resistance is good. 

 

Features

 

1: Low thermal expansion / Low calcining expansion/ Low heat expansion/ Low thermal dilatation
2: The thermal conductivity reduces along with the temperature growth
3: Good thermal shock resistance performance
4: Stable chemical characters
5: Excellent abrasion resistance/ abrasion-ability/ wear resistance/ wearability/
6: High performance of alkaline medium erosion resistance
7: The refractoriness under load can be 1700℃
8: Dense crystal structure
9: High bulk density
10: High mechanical strength at normal and high temperature
11: Low creep and low permanent liner change rate.
