Clay refractory bricks for coke oven are widely used in many parts of coke oven because of their unique physical and chemical properties. The following is its specific application:

I. Regenerator

Regenerator is an important part of coke oven, and its working feature is large periodic temperature fluctuation. Clay refractory brick is suitable for sealing wall, single wall, partition wall and checker brick of regenerator because of its good thermal shock resistance and low thermal conductivity. These parts need to withstand the impact of high-temperature exhaust gas and periodic temperature changes, and the thermal shock resistance of clay bricks can effectively reduce the damage caused by temperature fluctuations.

II. Small flue

Small flue is the key channel for coke oven exhaust gas, and its lining needs to withstand the erosion and mechanical impact of high temperature exhaust gas. Clay refractory bricks are widely used in the lining of small flue because of their good acid resistance and slag resistance.

III. Furnace top

The top of the coke oven is the upper structure, which needs to bear high temperature and mechanical load. Clay refractory brick can be used for building the roof of small coke oven, and its good thermal insulation and thermal shock resistance can effectively protect the roof structure.

IV. Around the riser and coal loading hole

The temperature around the riser and coal hole fluctuates greatly, and the thermal shock resistance and thermal insulation of clay refractory brick make it an ideal choice for these parts. These parts need to be opened and closed frequently, and the temperature changes sharply. Clay bricks can effectively reduce the structural damage caused by temperature changes.

V. Furnace door lining brick

The oven door is frequently opened and closed in coke oven operation, and the temperature changes dramatically. The thermal shock resistance and thermal insulation of clay refractory bricks make it an ideal material for oven door lining bricks.

VI. Repair of furnace wall of carbonization chamber

In the long-term operation of coke oven, the wall of carbonization chamber may be cracked and peeled off. Clay refractory brick or clay refractory mud can be used for hot repair of furnace wall, and its good thermal shock resistance and repair performance can effectively prolong the service life of furnace wall.

VII. Other parts

Clay refractory bricks are also used in other secondary parts of coke ovens, such as flue lining and insulation layer. These parts have relatively low requirements for high temperature resistance and corrosion resistance of refractories, but they need good heat insulation and thermal shock resistance.

VIII. Summary

Clay refractory bricks for coke oven are widely used in many key parts of coke oven because of their good thermal shock resistance, acid resistance and thermal insulation performance. Although its load softening temperature and thermal conductivity are not as good as those of silicon brick, clay brick is still an indispensable refractory in parts with large temperature fluctuation or high requirements for.
