High Alumina Brick Checker Refractory Products for Steel Industry
The Description:
Checker brick is a heat transfer medium in hot blast furnace, glass kiln and coke oven heat storage room. The brick type is made of orderly arrangement of lattice holes with a certain structure, and cold and hot gas pass freely through the holes above and below the lattice brick to complete heat exchange. Lattice brick features: strong heat exchange capacity, large heat storage area, reduce energy consumption, smooth ventilation, good volume stability, high temperature load creep performance

Product feature:
High Alumina Brick Checker Refractory Products for Steel Industry is produced of high quality bauxite clinker,it is formed by high pressure and sintered by high heat.its main minerals are mullite and corundum phase. The product has good properties o resisting physical high temperature and chemical erosion.It is widely used in different parts of blast furnace lining.
Checker brick features:
Strong heat exchange capacity, large heat storage area, reduce energy consumption, smooth ventilation, good volume stability, high temperature load creep performance, high density, low porosity, etc.
Checker brick classification:
Classification by material: can be divided into clay lattice brick, high aluminum lattice brick, mullite lattice brick, siliceous lattice brick, sillimanite lattice brick and so on.
According to the specification classification: can be divided into 7-hole lattice brick, 19-hole lattice brick, 31-hole lattice brick, 37-hole lattice brick.
Use of checker brick:
It is mainly used for heat transfer in the regenerator of blast furnace and heat transfer operation in the regenerator of flame furnace. In glass regenerator and coke oven regenerator, it plays the role of heat storage, heat exchange, energy saving and consumption reduction.
