subject: The Innovative Development Of Refractory [print this page] Such as high air temperature of the blast furnaces in the iron and steel enterprises, the operation of the thermal air flow and blast furnace large; in steelmaking and continuous casting, converter and electric furnace steelmaking technology advances, in particular the continuous improvement of high power and ultra-high power electric furnace. In the building materials industry, such as float glass production process of continuous development and the large glass melting pool, and the introduction of foreign advanced pit furnace and so on. All of this prompted the development and application of new refractories. China's Ministry of Industry and the recent official release issued in the new materials industry "12th Five-Year" development plan ", the refractories will pay more attention to the green of basic refractories, high-grade oxides and cast refractories, refractory chrome-free or low-chromium materials, energy saving kiln furniture, garbage incinerators, unshaped refractories, and other aspects of development, high-tech enterprise mainly to the high-tech, high value-added products will have a better chance.
Acid refractory silicon oxide as the main ingredient commonly used silica brick and clay brick. Neutral refractory aluminum oxide, chromium oxide, or carbon as the main ingredient. Containing more than 95% of alumina corundum products is a wider use high-quality refractories. Basic refractories, magnesium oxide, calcium oxide as the main ingredient, the common magnesia brick. A large number of refractory pre raw materials are required after mining by the crusher depending on the application processing to the industry's need for particle size, can be successfully applied for the processing of refractory raw materials, production of domestic well-known brands Zhengzhou East Granville Machinery Manufacturing Co., Ltd. various gravel crushing equipment, such as: crushing, jaw crusher, adjustable crushing crusher, impact crusher series of the broken, the gangue crusher, river gravel crusher, PE jaw crusher the PF counterattack crusher, high efficiency sand making for a variety of refractories demand applications, chippings.The following hardness minerals, rocks and refractories. Especially in refractory and mining industries than the average stone crushing machinery excellent results. In recent years, is widely used in crushing steel grit and other industries. Various types of crushers have different specifications, different use.
