Product Description

Andalusite bricks use corundum, andalusite as the main raw materials and strictly control the granularity of the raw materials. We apply new techniques and adopt multi-stage batching, matrix homogenization, determination of the best calcination temperature and other process measures. So, we have excellent andalusite bricks, which can fully meet the requirements of different parts and working environments of blast stoves and hot blast stoves.
