The silica brick for coke oven is a silicon refractory product used for building a coke oven with a quartz crystal as the main crystal phase.

 

Advantage:

  1. Good thermal conductivity.
  2. High refractoriness under load.
  3. Good creep resistance.
  4. High refractoriness.

 

Application:

Coke oven silica bricks are used to build regenerator walls, chutes, combustion chambers, carbonization chambers and furnace roofs of coke ovens.
