Product Description
The bottom pour bricks are dry pressed in the manufactuing, which contributes to the dimension with a very tight tolerance among the joints. We offer fireclay, high alumina and adalusite quality. The alumina ranges from 40% to 70%.
The bottom pour bricks meet the various metallurgical needs (such as ultra low carbon tolerances), steel grades & ingot casting practices of the customers.
