Checker Silica Brick For Hot-Blast Furnace
The Description:
Checker brick is widely recognized and accepted by the world ironmaking industry, which has many excellent 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 and plays the role of heat storage. In the process of heating cold air into hot air, it plays an extremely important role.

The Feature:
1. The checker silica brick has vertical conduits, which facilitate the removal of obstructed material.
2. Checker Silica brick should be very strong, especially the upper layer, because it is subjected to the action of high temperature, if the ash containing iron oxides deposited here, it will combine with the brick and melt, causing the brick to lose strength. The strength of brick is related to the thickness of brick; When the brick is thick enough, the center will not heat to the softening temperature.
3. Reduced heat loss.
4. It can ensure that the temperature difference between the inner layer and the outer layer of the furnace top brick is not large.
Application:
The use of the checker brick of the hot blast stove: the checker brick is mainly used in the hot blast stove, when the hot air is below 900ºC, the clay brick is generally selected; When the wind temperature is higher than 900ºC, the checker brick is high aluminum brick, mullite brick, sillimanite brick and silicon brick
