Silica bricks for coke oven is made of natural quartz stone with high SiO2 content (94%). Silica brick is used for coke oven's basic parts such as regenerator, chute, carbonization chamber, combustion chamber, coking chamber, furnace bottom and top, etc. The brick quality is one of the main factor that affect the service period of coke oven. With the enlargement of coke oven, the temperature in the main burning area has been rising, which requires higher quality bricks for oven.

Refractory coke oven bricks are coke oven bricks with tridymite as the main crystalline phase, used for building coke ovens. Modern coke ovens are large-scale heating equipment made of thousands of refractory materials and 10,000 tons of refractory materials. Silica brick for coke oven is a kind of siliceous refractory material, used to build coke oven with quartz crystal as the main phase. The modern silicate brick coke oven is a large-scale thermal equipment built with tens of thousands of tons of nearly 2,000 brick-like refractory materials, of which silica bricks account for 60% to 70% of the coke ovens. Coke oven silica bricks are used to build the regenerator wall, chute, combustion chamber, carbonization chamber and furnace roof of the coke oven.

The service life of coke ovens is about 20-30, some of which can reach 45a. The quality of coke oven bricks is one of the factors that affect the service life of coke ovens. With the expansion of coke ovens, the temperature of the main combustion zone has been rising, which requires coke ovens to use higher quality coke oven bricks.

What refractory materials are used in coke ovens?
Refractories For Coke Oven
Silica is the refractory material of choice, primarily because of its minimal creep at normal coke oven battery operating temperatures.

Advantages for Refractories For Coke Oven

 

1. SiO2≧ 94%.

2. RUL is 1650℃:

High thermal conductivity: Coke is made by coking coal in the coking chamber through the wall of the combustion chamber. Therefore, the silica refractory bricks used to form the wall of the combustion chamber should have high thermal conductivity. . Due to the regular coking and coke discharge of the coke oven, the temperature of the refractory silica bricks on both sides of the heating wall changes rapidly. The normal working temperature change will not cause serious cracking and peeling of the silicon brick. When the temperature exceeds 600°C, coke oven bricks have good thermal conductivity. Since the coke is heated by the conduction between the burner wall and the coking coal in the coking chamber, the coke oven bricks should have a higher thermal conductivity. In the temperature range of the combustion chamber of the coke oven, the thermal conductivity of refractory silica bricks is higher than that of fire clay bricks and high alumina bricks.

3. Good corrosion resistance of acid slag

4. Good stability under the high temperature:

The residual quartz content in silicon bricks with good crystal type conversion is 1% lower. During normal operation of the coke oven, coke oven bricks can maintain overall stability and airtightness.

5. True density 2.33g/cm³

6. High fire resistance under load: coke oven bricks must bear the dynamic load of the top coal wagon at high temperatures and need to be used for a long time without deformation. Requires higher softening temperature of coke oven bricks. The coke oven bricks can withstand the live load of the charging truck on the roof of the furnace and maintain its shape without changing the high temperature.

 

Application for coke oven bricks

Coke oven silica brick is mainly used for oven's regenerator, chute, carbonization chamber, combustion chamber, bottom and top of the oven.

The products can be made according to customers' requirements.
