Product Description

Product Description

 

The lattice brick of hot blast furnace is a kind of heat storage body, which is characterized by good volume stability, good creep performance under high temperature load, high density and low porosity.
Lattice brick is recognized and accepted by the world ironmaking industry, which has many thermal characteristics, such as strong heat exchange capacity, large heat storage area, smooth ventilation and low resistance. Lattice brick is a kind of heat transfer medium, which is mainly used in the middle and upper part of the regenerator of hot blast furnace. It plays an important role in the process of heating cold air into hot air.

Characteristic & Application

Product features:
Good volume stability
Excellent creep performance under high temperature load
High density and low porosity

Typical applications:
Lattice bricks are mainly used in hot blast furnaces. When the hot air is below 90ºC, clay bricks are generally selected. When the wind temperature is higher than 900ºC, the lattice brick is high aluminum brick, mullite brick, sillimanite brick and silicon brick.
