Product Description
The Fireclay Bricks&High Alumina 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 85%.
The Fireclay Bricks&High Alumina Bricks bricks are mainly used in blast furance, hot blast furance, electric furance, steel bucket, cement furance, glass furance and chemistry furance. Furthermore it can be used in the regenerator, stopper and water gap.
