The service temperature range of clay refractory bricks for coke oven mainly depends on its material properties and the specific parts of coke oven. The following is a summary of relevant information:

I. Fire resistance:

The fire resistance of clay refractory bricks for coke ovens is generally between 1690℃ and 1730℃. This means that in practical use, the highest temperature that clay refractory bricks can withstand is close to or reaches this range.

II. Load softening temperature:

The load softening temperature of clay refractory brick is usually between 1200℃ and 1400℃. This shows that the structural stability of clay refractory bricks will gradually decrease with the increase of temperature under high temperature load.

III. Actual temperature range:

In the regenerator and small flue of coke oven, clay refractory bricks can adapt to a wide temperature range, usually between 300℃ and 1000℃.

Clay refractory bricks can be used in areas with temperature ranging from 500℃ to 1100℃ for areas with large temperature fluctuations such as the furnace wall of the carbonization chamber.

The service temperature of clay refractory brick is generally 600℃~1000℃ in the parts with relatively low temperature such as furnace door and furnace top.

IV. Adaptability to temperature change:

Clay refractory bricks have good thermal shock resistance, can remain stable in the environment of rapid temperature change, and are suitable for parts with large temperature fluctuation in coke ovens.

To sum up, clay firebrick for coke oven is suitable for medium and low temperature environment, and its actual use temperature range is generally between 300℃ and 1100℃, and the specific use temperature needs to be selected according to different parts and working conditions of coke oven.
