Detailed Description

Zibo JUNXU TECHNOLOGY CO.,LTD is a professional ceramic fiber manufacturer located in Zibo, the ceramic fiber and refractory production base of China. We can guarantee the quality of our products. Moreover, we can offer professional and complete services to you, such as stable quality, fast delivery time and professional exporting service. Brown corundum is made mainly from bauxite, carbon materials and iron filings, smelting by high tempetures in electric spark furances. Brown fused aumina is the main chemical ingredient Al2O3, its content is between 94.5% and 97%, and the other containing a small amount of Fe, Si, Ti and so on. Its micro-hardness is HV 1800-2200. Its tenacity is higher than that SiC. The abrasive tools made of it are fit grind materials of all kinds, such as universal steel and gerveral alloy stell. It can be used to forge rough iron and hard bronze and make advanced refactory. Main functions: (1) As there is high temperature, corrosion resistance, high strength properties, it poured with steel sliding gate, smelting rare metals, special alloys, ceramics, iron-smelting furnace of the lining (walls and tubes); physical and chemical containers , spark plugs, heat-resistant anti-oxidation coating. (2) Due to high hardness, wear resistance, high strength characteristics, in the chemical system, used for a variety of reaction vessels and pipelines, chemical pump parts; to do mechanical parts, various molds, such as the Roberts mold, extrusion die nozzle pencil lead, etc.; do tool, die grinding, bullet-proof material, the human body joints, sealing ring mold. (3) Corundum heat preservation material , such as lightweight corundum brick, corundum hollow ball and fiber products, widely used in a variety of high-temperature kiln furnace walls and roof, both high temperature-resistantance and heat-preservation.
