glass furnace, sodium silicate furnace, frit furnace, metallurgical furnace, ceramic shuttle kiln, cement rotary kiln, tunnel kiln, pizza oven etc.
Classification & Difference
1. Classification
Phosphate brick high alumina bricks are divided into phosphate bricks and phosphate wear bricks.
2. Difference
❉ Phosphate brick is used as a binder for phosphate, and phosphate wear-resistant brick is a binder of diammonium phosphate.
❉ Generally divided into resistant phosphate and high temperature phosphate. These two bricks are not much different because phosphates have better wear resistance.
❉ High-grade phosphate bricks are high-load soft phosphate bricks. Because phosphate bricks are combined with phosphoric acid, the load is generally low. Above 1300 ℃ ~ 1450℃.
