1. High temperature resistant mullite brick
Mullite lightweight brick has small holes inside it, so it has high apparent porosity.It can decrease heat loss of furnace wall, then save fuel.Meanwhile, lightweight means less heat storage, fast temp-up and temp-down, which can increase cyclic operation.
