60% 70% Al2O3 High strength High Alumina Refractory Precast block for kiln masonry
High Alumina Refractory precast block produced by us is made of refractory aggregates, powders, binders, addictives, water or other liquids, puried into a fixed shape fire proof brick. The product can be precast into a variety of shapes, with characters of good thermal shock stability, high strength, good spalling resistance, energy saving and good air tightness.
According to the material the refractory precast block can be devided into high alumina, corundum, fireclay, mullite fire proof bricks.
High Alumina Refractory precast block advantages:
1, Can quickly repair the furnace thus improving the furnace operating rate.
2, 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.
