Alumina Hollow Ball For Refractory Bricks

Alumina hollow ball is a new type of high temperature insulation material. The alumina hollow sphere is a national standard first-grade industrial alumina powder, which is melted in a three-phase electric arc furnace, and then the molten liquid alumina is blown into a hollow sphere by using compressed air to obtain an alumina hollow ball, and the crystal form is alpha alumina. Microcrystals. The alumina hollow sphere is the main body, which can be made into various shapes. The maximum use temperature is 1800 ℃, the mechanical strength of the product is high, which is several times that of the general lightweight product, and the bulk density is only one-half of the corundum product.

Product Application:

Alumina hollow ball and its products are light refractory materials with high temperature resistance and energy saving. Alumina hollow spheres can be used for high temperature and ultra high temperature insulation fillers, high temperature refractory concrete lightweight aggregates, high temperature castables, etc. Alumina hollow ball refractory bricks 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.
