Production process

Professional production of corundum mullite bricks

Quasi-shrinkage-free casting


Quasi-shrinkage-free casting is vertical casting, and its casting size is larger than the required size. The shrinkage cavity is mainly concentrated at the upper end. After annealing, the shrinkage cavity part at the upper end is cut off, and the rest is quasi-shrinkage-free brick of the required size. Therefore, the lower part of the brick is very dense and is mostly used for pool wall.
