The development of refractory industry is closely related to the quantity of domestic mineral resources. Bauxite, magnesite and graphite are the three major refractory materials. However, China is one of the three largest bauxite exporters in the world, and the reserve of magnesite is also a major export country of graphite. The rich resources have supported the rapid development of China's refractory materials for ten years. Magnesite manufacturer
At the same time, there are many refractory enterprises in China, and their scale, process technology, control technology and equipment level are uneven. Advanced production methods coexist with backward production methods. The overall level of cleaner production in the industry is not high, and the task of energy conservation and emission reduction is arduous.
With the "12th Five Year Plan" period, China will accelerate the elimination of backward and energy consuming capacity. The industry will focus on developing and promoting new energy-saving furnaces, developing comprehensive energy-saving technologies, carrying out energy management, emission control of "three wastes" and recycling of "three wastes". It is committed to recycling and reusing used refractory materials, reducing solid waste emissions, improving the comprehensive utilization rate of resources, and comprehensively promoting energy conservation and emission reduction.
The Refractory Industry Development Policy points out that the unit consumption of refractory materials in China's steel industry is about 25 kg per ton of steel, and will fall below 15 kg by 2020. In 2020, China's refractory products will be more long-lived, energy-saving, pollution-free and functional, which will meet the needs of national economic development such as metallurgy, building materials, chemicals and emerging industries, and improve the technical content of export products.
Refractory materials are used in steel, nonferrous metals, glass, cement, ceramics, petrochemical, machinery, boilers, light industry, electric power, and other fields of the national economy. They are the basic materials for the production and operation of the above industries and technological development, and play an important role in the production and development of high-temperature industries.
Since 2001, the refractory industry has maintained a good growth trend and has become a major producer and exporter of refractories in the world, driven by the rapid development of high temperature industries such as steel, nonferrous metals, petrochemical and building materials. In 2011, China's refractory production accounted for about 65% of the world's refractory production and sales.
The output of refractory raw materials and products increased steadily from 2001 to 2010, of which the output at the end of the Tenth Five Year Plan was about twice that of 2001; In 2010, the output of refractory products reached 28.0806 million tons, about three times that at the end of the Tenth Five Year Plan. As of 2011, there were 1917 enterprises above designated size in China's refractory industry, with more than 300000 employees, achieving sales revenue of 337.679 billion yuan and product sales profit of 47.737 billion yuan.
However, due to disorderly mining, low level of technology, low level of comprehensive utilization of resources and serious waste, the above mineral resources, especially high-grade refractory raw material resources, have become less and less, and resource conservation and comprehensive utilization of resources have become a top priority.
