High Strength Wear Resistant Castable Supply

High strength wear resistant castable is mainly corundum or high quality alumina clinker, silicon carbide as aggregate. And introduce a variety of micro powder, superfine powder, corundum powder and additives as admixtures prepared. Mainly used for circulating fluidized bed boiler air plate, slag discharge tube, furnace chamber dense phase area and furnace outlet, cyclone separator, inlet and outlet flue, return device, slag cooler and other structures are complex, can be cast and vibration less parts.

The important indexes of macrostructure of the series wear resistant castable are porosity, water absorption, permeability, pore diameter distribution, volume density, true density, etc. These are important indexes to evaluate the quality of refractories. In addition to the direct expression of their own significance, these indicators can also be closely related to other properties of high strength wear resistant castable, such as thermal shock resistance, slag resistance, mechanical properties, thermal conductivity and so on.

The formation of wear resistant castable is closely related to the raw material and manufacturing process, including the type, ratio, particle size, mixing, molding, drying and firing conditions of the raw material. Because the macroscopic structure of the refractory castable not only reflects the process of the high strength wear resistant castable, but also affects its many important properties, the study of the macroscopic structure of the refractory castable has an important guiding role for improving the process and performance.

Its main characteristics are high strength, erosion resistance, good thermal shock stability and so on, the operating temperature of 900℃ or so. It also has the advantages of small wear loss, high strength, controllable shape, strong integrity, simple construction and good construction performance. Due to the addition of high molecular polymer, the concrete base has a strong bond, which is used in many fields.
