Silica brick is an acidic refractory mainly composed of tridymite, cristobalite and a small amount of residual quartz and glass phases
Silica brick: an acidic refractory mainly composed of tridymite, cristobalite and a small amount of residual quartz and glass phases. Its silica content is more than 94%, it has anti-acid slag erosion performance, high high temperature strength, high load softening temperature, long-term use in high temperature flower wells without deformation, but low thermal shock stability (heat exchange in water is 1-4 Second-rate).
Silica bricks for coke ovens are siliceous refractory products used for building coke ovens with tridymite as the main crystal phase. Coke oven silica bricks are used to build regenerator walls, ramps, combustion chambers, carbonization chambers and furnace roofs of coke ovens. Silica brick is an acid refractory material with good resistance to acid slag erosion. The softening temperature under load is as high as 1640-1670 °C, and the volume is relatively stable in long-term use at high temperature.
Coke furnace silicon bricks are mainly used in the heat storage room, oblique road, charcoal room, combustion room, top of the furnace, and bottom of the furnace.

The heavy part of the raw materials for the chrome zirconium corundum composite brick is sintered tabular corundum, high-purity chromium oxide, high-purity zircon, and Guangxi white cement.As the main raw material, the light part of the raw material is made of 47 mullite, kyanite, floating beads and coke gemstones as the main raw materials. During molding, a separator is set in the middle of the mold, and heavy materials and light materials are added at both ends. After high pressure molding , finished products made of high temperature sintering.
The unshaped refractory material used when repairing the lining of thermal equipment by spray construction method is called refractory gunning material. It is made of a refractory set with a certain particle gradation
