High alumina poly light ball insulation brick

High alumina poly light ball insulation bricks, also known as high quality high alumina pol -light bricks, are produced by using the blast furnace charge as the main raw material, supplemented by appropriate admixtures, and using the poly-light loss-on-fire method. The product has the advantages of high strength, good thermal stability, little change in returned fiber, and small thermal conductivity. High quality high alumina poly light ball bricks are used in furnace linings (not corroded by solutions) and thermal insulation layers in metallurgy, machinery, ceramics, chemical, and other industries, and are an ideal energy-saving product. The operating temperature is below 1350°C.

High alumina poly light ball insulation bricks have high porosity, good thermal insulation performance, and high-temperature resistance, and are suitable for the thermal insulation layer and thermal insulation layer of masonry industrial kilns, which can reduce the weight of the furnace body, shorten the kiln time, reduce heat diffusion, and protect the furnace. temperature uniformity and so on.
