Acid resistant bricks for coke ovens

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.

Acid resistant refractory gunning material is used for spraying of blast furnaces, hot blast stoves, hot blast pipes, flue protection layers, working layers, etc.

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

The high-alumina bricks are mainly used in the regenerator of the hot blast stove. The lattice bricks with a certain structure are arranged in an orderly manner, and the upper and lower through holes of the lattice bricks can allow the gas to pass through.

Corundum refractory castable has the characteristics of high strength and good fluidity, which is convenient for construction. It is mainly used for the parts that are easy to be washed and worn, such as the combustion chamber, separator and flue of circulating fluidized bed boiler.
