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.

Insulation castables are mainly made up of lightweight refractory aggregates, powders, and binder additives.

Fireclay bricksis suitable for supporting hot blast stoves of large, medium and small blast furnaces

Refractory castable is a kind of refractory material that does not need to be formed and has good fluidity after being fired and stirred with water.

The refractory pre -production is the category of irregular refractory materials, also known as the prefabricated block of the pouring materials, and the irregular refractory prefabricated block.

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

Anhydrous taphole mud/taphole clay refers to taphole mud made of tar, resin, etc. as binders and corundum, bauxite, clay, silicon carbide, coke powder, etc. as raw materials. Anhydrous carbon taphole mud is made by a mud mill. When rolling, oil is added first, then block materials (clay and asphalt), and then powder materials (coke powder and clinker powder) are added after crushing. After pressing and mixing, the mud can be produced when it meets the standards.
