The Role Of Refractory Materials

    Refractoriness of not less than 1580 ℃ of a class of inorganic non-metallic materials. Refractory degree refers to the refractory cone specimen in the absence of load conditions, resistance to high temperature effect without softening the melting of the Celsius temperature. But only to the definition of refractories can not fully describe the refractory, and 1580 ℃ is not absolute. It is defined as materials that are allowed to be used in high temperature environments where physical and chemical properties are called refractory materials. Refractory materials are widely used in the metallurgical, chemical, petroleum, machinery manufacturing, silicate, power and other industrial fields, the largest in the metallurgical industry, accounting for 50% of the total output of 60%.Refractory Materials

    Refractory materials used in iron and steel, nonferrous metals, glass, cement, ceramics, petrochemical, machinery, boilers, light industry, electricity, military and other national economy in all areas, is to ensure that the production and operation of the industry and essential technical development essential materials, In the development of high temperature industrial production plays an irreplaceable important role.Refractory Materials

    Since 2001, in the iron and steel, nonferrous metals, petrochemical, building materials and other high-temperature industrial development of the strong pull, the refractory industry maintained a good growth trend, has become the world's refractory production and export power. China's refractory production in 2011 accounted for about 65% of the world, production and sales ranked first in the world refractories.Refractory Materials

    From 2001 to 2010, the output of refractory raw materials and products increased steadily, of which the "15" was about 2 times of that in 2001; the output of refractory products in China reached 280.080 million tons in 2010, about three times the end of the "fifteen". As of 2011, China's refractory industry, a total of more than 1917 enterprises, employing more than 30 million people, sales revenue 3376.79 billion yuan, the product sales profit of 47.737 billion yuan.

However, due to disorderly mining, the level of processing technology is not high, the level of comprehensive utilization of resources, waste is more serious, the above-mentioned mineral resources, especially high-grade refractory raw material resources have been less and less resources, comprehensive utilization of resources is a matter of urgency The

    Refractory materials industry must guide the raw materials mining organization scientific exploitation, the resources to optimize the comprehensive utilization, especially the different grades of mineralization of the mineralization, to eliminate indiscriminate digging, and gradually promote the rational use of resources, so that the limited resources to maximize Role, to achieve sustainable development.Refractory Materials
