Fire 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, and military industry. They are essential basic materials to ensure the production and operation of the above-mentioned industries and technological development. It plays an irreplaceable important role in the development of high-temperature industrial production.

Since 2001, driven by the rapid development of high-temperature industries such as steel, nonferrous metals, petrochemicals, and building materials, the refractory industry has maintained a good growth momentum and has become the world's largest producer and exporter of refractory materials. In 2011, China's refractory production accounted for about 65% of the world's total, and its production and sales volume steadily ranked first in the world.

From 2001 to 2010, the output of refractory raw materials and products increased steadily. Among them, the output of refractory products at the end of the "Tenth Five-Year Plan" was about twice that of 2001; in 2010, the national output of refractory products reached 28.0806 million tons, about three times that of the end of the Tenth Five-Year Plan. As of 2011, China's refractory materials industry had 1,917 above-scale enterprises with more than 300,000 employees, and realized sales revenue of 337.79 billion yuan and realized product sales profits of 47.737 billion yuan.

However, due to the low level of disorderly mining and processing technology, the low level of comprehensive utilization of resources, and the more serious waste, the above-mentioned mineral resources, especially high-grade refractory raw materials resources, have become less and less, and resource conservation and comprehensive utilization of resources are urgent tasks. .

Song Zhenyu believes that the refractory industry must guide raw material mines to organize scientific mining, optimize and comprehensive use of resources, especially the homogenization of minerals of different grades, prevent excessive mining and digging, and gradually promote more rational use of resources, so that limited resources can be used. Maximize the role to achieve sustainable development.

The development of the refractory industry is closely related to the retention of domestic mineral resources. Bauxite, magnesite and graphite are the three major refractory materials. China is one of the world's three largest exporters of bauxite, the world's largest reserves of magnesite, and a large exporter of graphite. The rich resources have supported China's refractory materials for a decade of rapid development.

At the same time, there are a large number of refractory companies in China, with varying scales, process technology, control technology, and equipment levels. Advanced production methods coexist with backward production methods. The overall clean production level of the industry is not high, and the task of energy conservation and emission reduction is arduous.

With the "Twelfth Five-Year" period, China is speeding up the elimination of backward and high energy consumption capacity, the industry will focus on the development and promotion of new energy-saving furnaces, development of comprehensive energy-saving technologies, energy management, emission control of "three wastes" and resource utilization of "three wastes" Recycling, etc. Committed to resource recycling and reuse of refractory materials after use, reduce solid waste emissions, improve the comprehensive utilization of resources, and comprehensively promote energy conservation and emission reduction.

The "Refractory Industry Development Policy" pointed out that the unit consumption of refractory materials in China's iron and steel industry is about 25 kg per ton of steel, and it will fall below 15 kg by 2020. In 2020, China's refractory products will have longer life, more energy-saving, pollution-free, and functional products. Products will meet the needs of national economic development such as metallurgy, building materials, chemicals, and emerging industries, and will increase the technical content of export products.
