Hequ million of energy-saving materials Co., Ltd. was established in 2004, is a research and development, production, construction and installation of an integrated joint-stock enterprises. The company is located in the provinces of Shanxi, Shaanxi and Inner Mongolia at the junction Hequ County, the company covers an area of ??over 26,000 square meters, with a total investment of more than 20 million yuan, and has a high, intermediate researchers and technical staff. In the establishment of casting factory mainly engaged in the production and marketing of high, medium and low-chromium alloy casting ball and wear-resistant materials such as cast products segment. Bauxite (aluminous soil; bauxite), also known as alumina or bauxite, the main ingredient is alumina, alumina hydrate system containing impurities, is an earthy minerals. White or gray, because iron and brownish yellow or reddish. Density of 2.4-2.5g / cm3, hardness of 1 to 3, an opaque, brittle. Extremely difficult to melt. Insoluble in water, soluble *, sodium hydroxide solution. Mainly used for aluminum smelting, manufacture refractories. Refractory bauxite industry term usually refers to calcined Al2O3> = 48%, while containing low Fe2O3 bauxite, bauxite clinker is calcined bauxite. Clinker for gray and dark gray, light yellow, it is mainly used for high alumina refractories, can also be used to produce fused corundum. High bauxite is based AL2O3 content and Fe2O3, TiO2, CaO + MgO, K2O + Na2O and other impurities and clinker bulk density and water absorption and other indexes to classification
