The high strength castable refractory steel fiber reinforced wear-resistant castable is prepared by adding special grade aluminum bauxite clinker or corundum as aggregate and powder, adding binder, admixture and heat-resistant stainless steel fiber.
The high strength castable refractory steel fiber reinforced wear-resistant castable is prepared by adding special grade aluminum bauxite clinker or corundum as aggregate and powder, adding binder, admixture and heat-resistant stainless steel fiber. It has the characteristics of high compressive strength, high flexural strength, thermal shock resistance, wear resistance and volume stability. Such high strength castable refractory is suitable for furnace wall, furnace roof, furnace of cemented bed boiler, kiln mouth, cooling machine and feed tank of cement kiln. And other parts.
Applications of Steel Fiber Castable:
• Steel casting furnaces
• Iron making furnaces
• Glass kiln
• Cement kiln
• Ceramic tunnel kiln
Advantages of Steel Fiber Castable:
•High strength,
•Long service life
•Good wear resistance
•Thermal shock resistance,

The heat resistant refractory cement also well known as calcium aluminate cements, and high alumina castable refractory cement. Generally there are 4 grades of refractory cement according to Al2O3 content, A600, A700，A900 and CA-70.
Zirconium corundum brick is also named AZS brick. It is based on three chemical components of the Al2O3-ZrO2-SiO2 ternary phase diagram and widely used for glass kiln. The glass kiln brick is arranged according to the order of its contents.
Mag carbon bricks are made of fused magnesia, high-purity magnesia and graphite, and are formed by high pressure molding and low temperature treatment. Different grades of mag carbon bricks can be selected according to different smelting conditions , service life in heats and smelting steel grades.
