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 |
