Production process

Professional production of corundum mullite bricks

Shrinkage-free casting

Shrinkage-free casting is vertical casting, the casting size is larger than the required size, the shrinkage is concentrated on the upper end, the shrinkage part of the upper end is cut off after annealing, and the rest is shrinkage-free brick of the required size. Therefore, the brick is very dense and is mostly used for pool wall and liquid hole.
