Rerefractory materials used in iron and steel, non-ferrous metals, glass, cement, ceramics, petrochemical, machinery, boilers, light industry, power, military industry and other areas of the national economy, is to ensure the operation of the above industry consumption and technology essential basic materials, in high temperature industrial consumption development plays an irreplaceable role.
Since 2001, under the strong pull of high-speed expansion 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 consumer and exporter of refractory materials in the world. In 2011, China's output of refractories accounted for about 65% of the world's total, ranking first in the world in production and sales.
The output of refractory raw materials and products increased steadily from 2001 to 2010, which was about twice that of 2001 at the end of the Tenth Five-Year Plan. In 2010, China's output of refractory products reached 280,80,600 tons, about three times that of the end of the Tenth Five-Year Plan. By 2011, there were 1,917 enterprises above designated size in the refractory industry in China, with more than 300,000 employees, achieving sales revenue of 337.679 billion yuan and sales profit of 47.737 billion yuan.
However, due to the disordered mining, low level of processing technology, low level of comprehensive use of resources and serious erosion, the above-mentioned mineral resources, especially high level refractory raw materials resources have become less and less, waste resources and comprehensive use of resources are urgent.
The development of refractory industry is closely related to the quantity of international mineral resources. Bauxite, magnesite and graphite are three refractory raw materials. China is one of the world's top three exporters of bauxite, with the world's largest reserves of magnesite and a major exporter of graphite. Rich resources have supported China's refractories through a decade of rapid development.
At the same time, China has a large number of refractory enterprises, the scale of enterprises, technology, control technology, equipment level of good and bad, advanced consumption mode and backward consumption mode coexist. The level of clean consumption of the whole industry is not high, and it is difficult to fulfill the obligation of energy conservation and emission reduction.
During the 12th Five-Year Plan period, China will speed up the elimination of outdated and high-energy production capacity. The industry will focus on the development and implementation of new energy-saving furnaces, the development of comprehensive energy-saving technologies, power management, emission control of "three wastes" and the recycling of "three wastes". Efforts are made to reuse and reuse refractory materials after use, add and reinforce waste emissions, improve the comprehensive utilization rate of resources, one-sided promotion of energy conservation and emission reduction.
According to the Refractory Industry Development Policy, the single consumption of refractories in China's iron and steel industry is about 25 kilograms per ton of steel, which will drop to less than 15 kilograms by 2020. In 2020, there will be a large increase in the short-life, energy-saving, pollution-free and functional products of refractories in China, which will meet the needs of the national economy such as metallurgy, building materials, chemical industry and emerging industries, and improve the technical content of export commodities.
