Coke ovens mainly use bricks

Thread Content

There are 6 main types of bricks used in coke ovens: Silica bricks have strong high-temperature resistance; their main component is silicon dioxide, with a silicon content of over 95%. Clay bricks are primarily used in regenerator chambers and at the top of the oven. Grid bricks are used in regenerator chambers to ensure even distribution of gases inside, thereby achieving uniform heating along the length of the coke oven and facilitating heat exchange. Insulating bricks are placed on the outer layer of the grid bricks, while floating bead bricks are used on the bottom of the oven to reduce heat loss from that area, thus lowering the temperature in the basement and improving the operating conditions at the oven bottom. High-alumina bricks are neutral refractory materials with an alumina content of over 48%. It has advantages such as low high-temperature creep, strong erosion resistance, and good thermal shock stability. Cylinder bricks are mainly used in wet quenching towers and coke cooling platforms ； Steel bricks remain unchanged in extreme heat and cold
