Fire proof refractory brick , Refractory Products For Roller Hearth
Kiln
Description:
Refactory brick in roller kiln must be have a high temperature
resistance ,and a high thermal shock resistance ,because the roller
kiln is away in the running situation ,so this kind of refractory
brick should have a high strength ,and can resistant the wearing
situation .in a quick description,the refractory brick should have
some basic feature in following:
1. Thermal shock resistance;
2. high strength;
3. good wear resistance.
4. a high thermal stability .
Applications:
1. Steel furnaces
2. Iron making furnaces
3. Glass kiln
4. Ceramic tunnel kiln
5. Cement kiln
Specifications:
Andalusite bricks
