Silica Perforated Checker Refractory Brick Unshaped Silica Brick
The Description:
Checker brick is widely recognized and accepted by the world of ironmaking, a heat-carrying heat storage body with strong heat exchange capacity, large heat storage area, smooth ventilation, low resistance and many other superior thermal characteristics. 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:
Silica brick for coke oven (silica brick for coke oven) refers to the silica refractory products used for laying coke oven with squamous quartz as the main crystal phase. Modern coke oven is a huge thermal equipment built by thousands of brick types and tens of thousands of t refractory materials. Silicon brick is the main material of its masonry, constituting the basic part of the coke oven: regenerator wall, ramp, combustion chamber, carbonization chamber, furnace top, etc., accounting for 60%-70% of the total refractory brick a coke oven furnace service of about 20~30a, some as high as 45a. The quality of silicon brick of coke oven is one of the factors affecting the service length of coke oven. With the large scale of coke oven, the temperature of main fire passage increases, and the quality of silicon brick of coke oven becomes more important.
