ZHENJIN REFRACTORIES founded in 1985. It is a manufacturing enterprise integrating research and development, productions, sales, international trade and technical services. Refractory products and services for cement, lime, non-ferrous, glass, building materials and metallurgical industries.
During the production of corundum mullite bricks, a certain thickness of thermal insulation layer material is designed and produced on its non-working surface according to the conditions of use, and special production technology is used to combine two different materials into a whole. Under the premise of keeping the thermal expansion rate close to the same, a piece of product has high temperature resistance, erosion resistance, high strength, erosion resistance and thermal insulation functions, which can effectively solve the problem that the double-layer masonry of the rotary kiln cannot be built with thermal insulation materials.
