High alumina precast refractory shape fire proof brick
Precast refractory shape fire proof brick is made of refractory aggregates, powders, binders, addictives, water or other liquids, puried into a fixed shape fire proof brick. According to the material the precast refractory shape fire proof brick can be devided into high alumina, crundum, fireclay, mullite fire proof bricks.
Precast refractory shape fire proof brick can be precast into a variety of shapes, it can quickly repair the furnace thus improving the furnace operating rate. We can solve the technical problems in the process of building the furnace and design numbers of construction programs according to the customers' requirements and furnace condition.
Precast refractory shape fire proof brickwith features of:
High strength
Good thermal shock stability
Good spallling resistance
No seams and good air tightness
Less heat loss and energy saving
