Alkali resistant brick for cement kiln

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.

The Al2O3 content of clay heat Clay insulating refractory bricks is generally more than 40%, and the Fe2O3 content is less than 2.0-2.5%. The clinker in the ingredients is 65-85%, and the combined clay is 35-15%. The crushed bonded clay and the finely ground clinker are mixed and milled, and then mixed with the granular clinker to make semi-dry mud, high pressure molding, and sintering at about 1400 ℃, with good performance.

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.

Corundum bricks are mainly used in iron-making blast furnaces and blast furnace hot blast furnaces, refining furnaces outside steel-making furnaces, sliding water heaters, glass melting furnaces and petrochemical industrial furnaces, etc.

The alumina ball is also called the high aluminum accumulation of heat ball.High alumina refractory ball is based on bauxite as the mainly raw refractory material.Adding powder and additives and anchoring agent.After proportioning, molding and high sintering to make it.The production engineering of high alumina refractory ball is similar to that of high alumina refractory brick.It should be based on the properties of raw materials,high alumina refractory ball requires production conditions and other factors to determine.

Brown Fused Alumia powders are fused wIth premium raw materials and 3500 KVA furnace. It is perfect material specifically manufactured to be used for general abrasive applications in bonded abrasive tools, polishing and sandblasting grit. It has lower hardness and abrasive capacity than diamond, boron carbide, and silicon carbide, it is widely used for grinding ferrous materials, finishing tough and hard materials. It is also be used as high-class refractory materials. Brown Fused Alumia is offered in macro and micro powder form, in both F and P grades. 

Calcined alumina is a product obtained by calcining aluminum hydroxide at high temperature to partially or almost completely convert it into aAl2O2.

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.
