Silica Bricks For Coke Oven Introduction
Silica Brick for Coke Oven is a siliceous refractory product used for building a coke oven with a quartz crystal as the main phase. The modern silicate brick coke oven is a large-scale thermal equipment built by tens of thousands of tons of nearly 2,000 kinds of brick-type refractory materials, in which the amount of silicon brick used in coke oven accounts for 60% to 70%. Coke oven silica bricks are used to build regenerator walls, chutes, combustion chambers, carbonization chambers and furnace roofs of coke ovens.
Silica Bricks For Coke Oven Application
1.Coke oven silica bricks are used to build chutes
2.Coke oven silica bricks are used to build regenerator walls.
3.Coke oven silica bricks are used to build combustion chamber
4.Coke oven silica bricks are used to build carbonization chambers
5.Coke oven silica bricks are used to build furnace roofs of coke ovens.
Silica Bricks For Coke Oven Chracteristics
1.The load softening temperature is high.Silica refractory brick for coke oven must withstand the dynamic load of the coal loading vehicle on the top of the furnace at high temperature,require long-term use without deformation.Therefore, the softening temperature of the coke oven silicon brick is required to be high.
2. High thermal conductivity. Coke is made by coking coal in the carbonization chamber by the wall of the combustion chamber, so the silica refractory bricks for Silicate bricks coke oven that build the combustion chamber wall should have a high thermal conductivity.
3. Good thermal shock resistance. Since the coke oven is periodically loaded with coal and coke, causing the temperature of the on both silicon firebricks used in coke oven sides of the combustion chamber wall to change drastically, the coke oven silicon brick is required to have good thermal shock resistance.
4. The high temperature volume is stable.
