Andalusite bricks Introduce:
Andalusite bricks use corundum and andalusite as the main raw materials and strictly control the particle size of the raw materials, apply a new process, adopt multi-stage ingredients, matrix homogenization, determine the best calcination temperature and other process measures, and have excellent performance andalusite bricks , which can fully meet the use of blast furnaces and hot blast stoves in different parts and working environments.
Features of Andalusite bricks:
1. High cold crushing strength
2. High refractoriness under the load
3. Good creep resistance
