Refractory materials are used in various fields of the national economy such as steel, non-ferrous metals, glass, cement, ceramics, petrochemicals, machinery, boilers, light industry, electric power, military, etc., and are essential materials to ensure the production and operation of the above-mentioned industries and technological development. It plays an irreplaceable role in the development of high temperature industrial production.
Since 2001, under the strong development of high-temperature development of high-temperature industries such as iron and steel, non-ferrous metals, petrochemicals and building materials, the refractory industry has maintained a good growth trend and has become a major producer and exporter of refractory materials in the world. In 2011, China's refractory production accounted for about 65% of the world's total, and production and sales ranked first in the world's refractory materials.
From 2001 to 2010, the output of refractory raw materials and products increased steadily. The end of the "Tenth Five-Year Plan" was about twice that of 2001. In 2010, the output of refractory products nationwide reached 2,080,600 tons, about three times that of the end of the "Tenth Five-Year Plan". As of 2011, China's refractory industry has a total of 1917 enterprises above designated size, employing more than 300,000 people, achieving sales income of 337.679 billion yuan and achieving a sales profit of 47.737 billion yuan.
However, due to the disorderly mining and processing technology level, the level of comprehensive utilization of resources is relatively low, and waste is more serious. The above-mentioned mineral resources, especially high-grade refractory raw materials resources, have become less and less, saving resources and comprehensively utilizing resources is a top priority. .
