Refractory Brick for Ascension Pipe of Coke Oven
The Description:
The heat-shock resistant high alumina brick for coke oven is specially developed by selecting high quality first grade high alumina clinker and using third grade high alumina clinker and coke as high quality clay as the substrate. Low porosity, compact, good thermal shock resistance, high refractoriness up to 1750-1790ºC.
Coke oven is used to produce coke high temperature kiln, the main refractory materials are silica brick, clay brick and high aluminum refractory brick. The structure of coke oven is relatively complex, and the furnace body is mainly composed of combustion chamber, carbonization chamber, regenerator chamber and inclined flue. The coke oven carbonization chamber is an area where the coal is coked. The coal enters and begins to carbonize from the furnace head. After carbonization, the coke exits through the furnace door. At this time, cold air will enter the furnace door area to reduce the temperature. The function of coke oven is to decompose coke coal by heating, dry distillation and carbonization into coke under the condition of isolating air.

Application of high alumina firebrick in coke oven
The lining of the furnace door of the carbonization chamber and the furnace head at both ends of the carbonization chamber, when the furnace door is opened, the temperature suddenly drops from about 1000 ° C to below 500 ° C, exceeding the limit temperature of the volume stability of the silicon brick (573 ° C), generally using high thermal shock resistance and high load softening temperature of high-aluminum refractory brick or sillimanite brick. The thermal shock resistance of the product is improved by adding a certain proportion of sillimanite into the mixture of high alumina firebrick.
