Alumina Hollow Sphere Lightweight Refractory Castable
Alumina Hollow Sphere Lightweight Castable and its products are light refractory materials with high temperature resistance and energy saving, and are very stable in various atmospheres.
Alumina hollow sphere lightweight refractory castable is a new type of high temperature insulation material. It is made by melting industrial aluminum oxide in an electric furnace. The crystal form is a-Al2O3 microcrystal. Alumina hollow sphere lightweight refractory castable is the main body, which can be made into various shapes. The maximum use temperature is 1800℃, the mechanical strength of refractory product is high, which is several times that of the general lightweight product, and the bulk density is only one half of the corundum refractory product.
Alumina Hollow Sphere Lightweight Refractory Castable Feature
Alumina hollow sphere lightweight refractory castables are characterized by high load softening temperature, high strength and good thermal insulation performance.
Alumina Hollow Sphere Lightweight Refractory Castable Application
Alumina hollow sphere lightweight refractory castable can be used for high temperature energy saving (>30%) downdraft kiln, shuttle kiln, molybdenum wire furnace, tungsten rod furnace, induction furnace, nitriding furnace, etc. Significant effects will be achieved in reducing the weight of the furnace, transforming the structure, saving materials, and saving energy.
