Refractories Co., Ltd., Zhengzhou City shangzhuang understand basic refractory magnesium oxide, calcium oxide as the main component insulation brick clay, commonly used is magnesia. Magnesium containing more than 80% to 85% of the brick, for basic slag and iron slag has good resistance, refractoriness higher than the clay and brick. Mainly used for open hearth, basic oxygen furnace, furnace, non-ferrous metal smelting equipment and some high-temperature equipment. Special occasions refractory oxide material are high temperature insulating brick clay, such as alumina, lanthanum oxide, beryllium oxide, calcium oxide, and zirconium, refractory insulation bricks clay compound materials, such as carbides, nitrides, borides, silicides and sulfides; high temperature insulation bricks clay composite materials, mainly metal ceramics, high temperature inorganic coatings and fiber-reinforced ceramics. Refractories Co., Ltd., Zhengzhou City shangzhuang learned refractories industry has been a labor-intensive, resource-intensive industries, energy-intensive, resource dependence. After entering a new economic era, labor, energy costs increased, high-quality non-renewable resources are declining, the state environmental protection and energy yearly stringent requirements. Moreover, the rapid development of science and technology today, the technical level of iron and steel, glass, cement, nonferrous metals and other high-temperature industrial gradually increased, and then put a higher demand for refractories. If refractories enterprises rest on its laurels, it would be difficult to survive, the industry will be difficult to progress.
