Its products can be divided into metallurgy magnesite and magnesia products into two categories. Depending on the chemical composition and use can be divided metallurgical magnesia brick, brick magnesium, Mg-Al brick, brick, magnesium, calcium, carbon brick, and other varieties. Its performance is greatly affected by CaO / SiO2 ratio and impurities. High Purity Magnesia load softening point and thermal shock resistance are much higher than the general brick as well. Refractoriness high alkaline slag and iron slag has good resistance, is an important high-grade refractory (Refractory material). Multi-sintered magnesia products production, the firing temperature is generally between 1500 ~ 1800 ℃ Which monolithic refractories do good, in addition, you can also add a chemical binder made of unfired brick and monolithic refractories (Refractory material ). Mainly used for open-hearth, electric furnace, oxidation converter, nonferrous metal smelting furnaces, kilns, and basic refractories (basic refractory) calcining kiln. Exploitation of siliceous following problems compared with foreign: A, narrow the scope of application of the limitations in the vast majority of applications siliceous materials, the other in agriculture, there is a small amount of mechanical and electrical, chemical and environmental applications. In addition to these four foreign industrial sector, but also used in machinery, electronics, metallurgy industry stereotypes refractories, its apparent broad application areas. B, less product variety for a particular application area, the variety of siliceous patented product is significantly less than in other countries, to agricultural applications, for example, China's only medium soilless cultivation of flowers, fruit and vegetable fertilizer and three types of proprietary products . And foreign siliceous patented products, including animal washers, soil improvement, many bacteria culture carrier material, pesticides carrier, feed additives and other species, more fully utilize siliceous adsorption, cation exchange properties. Gap in building materials, petroleum chemical industry is also great. C, simple processing method for the direct use of general of siliceous ore and calcined use expansion after use, simple processing method. Abroad is often used for different applications in different processing methods to produce specific grain size, density or expanded to meet the needs of different multiples of siliceous products, their method is relatively advanced processing technology, innovative, diverse monolithic refractories Which do best corresponding more to promote and develop new products to broaden its use areas. D, fine-grained siliceous low utilization rate of the coarse-grained siliceous application has a good foundation, but fine (-0.3mm) silicon utilization is low, resulting in a waste of resources. What kind of monolithic refractories have, shangzhuang Refractories, Xiangtan monolithic refractories by shangzhuang Refractories Co., Ltd., Zhengzhou City. Zhengzhou City shangzhuang Refractories Co.
