Describe

Technical instructions

The precast brick with advantages of good thermal stability, excellent resistance to abrasion and erosion, as well as long work life, insure the long time stable production, life can reach 5 – 6 years .

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
