Compare standard size brick & precast brick 

life

Precast brick 3-5 years

Standard size brick 1-1.5 years

Reduce the number of maintenance, improve the utilization rate of coke oven, reduce labor costs, save material costs, prolong the service life. 

 energy conservation

The temp of the coke oven , can be lower 50’C than the standard size brick coke oven brick  

Improve the  temperature, shorten the distillation time, prolong the service life of the door.

environmental protection

 Easy to Control the  coke tar and coke dust come out from the door

To solve the smoke, dust and gas leakage problems; to prolong the service life, reduce maintenance and repair. 

Fast installation

Fast installation and maintain 

To reduce the labor intensity of the maintenance personnel; carbonization rate is greatly improved
