Silica bricks are highly resistant to burning and are classified as refractory products. They are fired at high temperatures. What characteristics do silica bricks possess under high temperatures? Next, we will provide a detailed explanation.

Excellent resistance to thermal shock is achieved at high temperatures. Due to the periodic charging and coke production in the coking furnace, it causes drastic temperature changes on both sides of the combustion chamber walls. Within the range of normal operating temperatures, there will be no severe cracking and spalling of the silicon bricks; however, above 600°C, the coke oven silicon bricks exhibit excellent resistance to thermal shock.

High temperature volume stability. In the silicon bricks with excellent crystal transformation, the residual quartz does not exceed 1%, and the expansion during heating is concentrated at around 600°C, after which the expansion slows down significantly.

During normal coke oven operation, the temperature does not drop below 600°C, and the modifications to the lining will not be significant, allowing for long-term stability and tightness of the lining.
