Silica Refactory Bricks for Coke Oven

Description of Silicon Brick for Coke Oven

Silicon Brick for Coke Oven is a kind of silicon refractory products used for masonry of coke oven, it is a kind of acid resistant brick. Silicon bricks for coke ovens are the main material for masonry coke ovens, and can be used for masonry coke ovens’ heat storage chamber wall, ramp, combustion chamber, and furnace roof.

Fireramo, as a manufacturer of silicon bricks for coke ovens, we have two kinds of silicon bricks for coke ovens for you to choose from: common silicon bricks for coke ovens and dense silicon bricks for coke ovens.

Dense coke oven bricks are more thermally conductive than ordinary coke oven bricks. Please refer to the table below or contact us for more details.

Characteristics of Coke Oven Bricks

High Purity & High Strength

Coke oven bricks are characterized by high purity, high density, high strength and low residual quartz content.

Resistant to slag and chemical corrosion

Silica bricks for coke ovens are acid refractory materials with strong resistance to attack by acid slag or acidic solution.

High load softening temperature

Silicon bricks for coke oven can withstand the dynamic load of coal loading car on the roof at high temperature and can be used for a long time without deformation;

High thermal conductivity

Silicon bricks for coke ovens have good thermal conductivity, which increases as the working temperature rises.

The use of silicon brick masonry coke oven can increase the temperature of the combustion chamber, shorten the coking time, increase the production capacity of the coke oven, prolong the age of the coke oven.

In the temperature range of the combustion chamber of the coke oven, the thermal conductivity of silicon bricks is higher than that of clay bricks and high aluminum bricks. And dense coke oven silica bricks can increase the thermal conductivity by 10%~20% than ordinary coke oven silica bricks;

Good thermal shock resistance at high temperature

Above 600℃, coke oven silica bricks have good thermal shock resistance;

Due to the periodic loading and discharging of coal and coke in the coke oven, which cause the temperature of silicon bricks on both sides of the wall of the combustion chamber to change drastically, it will not cause serious cracks and spalling of silicon bricks for coke ovens.

High-temperature volume stability

The residual quartz is not more than 1% in the silicon bricks with good crystal transformation. The expansion of silicon brick for coke oven when heated is concentrated before 600℃, and the expansion slows down significantly after 600℃.

In normal operation of coke oven, the temperature does not drop below 600℃, the change of masonry will not be big, and the stability and tightness of masonry can be maintained for a long time.

Application of silicon brick for coke oven

Silicon bricks for coke ovens are the main part of masonry coke ovens, accounting for 60%-70% of the overall refractory bricks for coke ovens.

Silicon bricks for coke ovens can be used for masonry of heat storage room wall, ramp, combustion room, carbonization room, roof and partition wall of coke ovens.

Because the coke oven with silicon brick has good thermal conductivity, thermal shock resistance and load softening temperature is high, it can also be used for glass pool kiln and kiln roof, pool wall, hot air furnace high temperature load-bearing parts, glass pool kiln, pool wall, high temperature load-bearing parts of hot air furnace, charcoal roaster and other thermal kilns .
