High alumina brick for coke oven
You may submit your questions by filling the form.
Refractory bricks is dense shaped refractory material.with high
refractoriness and mechanical behavior under high temperature,
refractory bricks is the nacessary material of high-temperature
services, mainly used for industrial furnaces and kinls and several
1. Main Characters: Refractoriness for the high alumina bricks for
coke oven is 1750-1790C, refractoriness under load is normally
above 1420~1550C. The brick has good erosion resistance to acid and
alkali slag but the thermal shock resistance it not good.
2. Applications: High alumina brick for coke oven are used in the
oven head of combustion zone, bottom of carbon zone. They can not
be used in wall bricks of carbon zone.
