The refractory ramming material is prepared from a high proportion of granular and powdery materials and a very low proportion of binders and other components, even all of which are composed of granules and powders, and are subject to strong ramming. Bulk materials for construction.
Anti stripping high alumina bricks are referred to as anti-stripping bricks or anti-stripping refractory bricks. Anti-stripping high-alumina bricks are widely used in my country's new dry process kiln, Libore kiln and wet process kiln, including kiln door cover, rising flue, cooling zone, decomposition zone, safety belt, transition zone, coolant rear Walls and side walls and beams with curved ceilings.
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.
It is widely used in the lining of the kiln working face which is in direct contact with the flame, and has become one of the research hotspots in recent years.
silicon mullite brick is a kind of refractory brick product made of super high alumina bauxite and silicon carbide as raw materials through a special sintering process. It has the characteristics of continuously forming a protective layer and reducing ring formation, and its heat resistance is also very good. The softening temperature under load can reach 1600 ℃, and the service life is long. Mainly used in the transition zone, decomposition zone and cooler of small and medium-sized cement kilns.

White corundum is made from industrial alumina powder, which is smelted in an arc at a high temperature above 2000 ℃ and then cooled. After crushing and shaping, magnetic separation to remove iron, it is divided into various particle sizes.
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.
