The role of refractory materials

Refractory materials are used in all 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 materials for ensuring the operation and technological development of these industries. In the high temperature industrial production plays an irreplaceable important role.
Since 2001, the refractory industry has maintained a good growth momentum with the rapid development of high-temperature industries such as iron and steel, nonferrous metals, petrochemicals and building materials, and has become the world's largest producer and exporter of refractory materials. China's refractory output in 2011 accounted for about 65% of the world, production and sales ranking the world's refractory materials first.
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" period was about twice that of 2001; the output of refractory products in China reached 28.0806 million tons in 2010, about three times that at the end of the "Tenth Five-Year Plan" period. As of 2011, China's refractory industry a total of 1917 above-scale enterprises, employing more than 30 million people, to achieve sales revenue of 337679000000 yuan, realize product sales profit 47737000000 yuan.
However, due to the disorderly exploitation, the processing technology level is not high, the level of comprehensive utilization of resources is low and the waste is more serious. The resources of the above mineral resources, especially the high-grade refractory raw materials have become fewer and fewer, resource conservation and comprehensive utilization of resources have become urgent tasks .
Song Zhen Yu believes that the refractory industry must guide the mining of raw materials scientific scientific exploitation of resources to optimize the comprehensive utilization of resources in particular, different grades of homogenization treatment to eliminate indiscriminate mining indiscriminate digging, and gradually promote the more rational use of resources, the limited resources to play Maximize the role of sustainable development.
The development of the refractory industry is closely related to the domestic holdings of mineral resources. Bauxite, magnesite and graphite are the three major refractory raw materials. China is one of the three largest exporters of bauxite in the world. Magnesite reserves rank first in the world and it is also a major exporter of graphite. The abundant resources support the rapid development of refractory materials in China for the past ten years.
At the same time, there are many refractories enterprises in China, and the scale, technology, control technology and equipment level of enterprises in China are uneven. The advanced mode of production coexists with the backward mode of production. The overall clean production industry is not high, energy-saving emission reduction task arduous.
With the acceleration of the elimination of backward and energy-intensive production capacity during the 12th FYP period, 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 and so on. Committed to the use of refractories after the resource and reuse, reduce solid waste emissions, improve the comprehensive utilization of resources, and comprehensively promote energy-saving emission reduction.
Refractories Industry Development Policy states that the unit consumption of refractories in China's steel industry is about 25 kg per ton of steel consumed and will drop below 15 kg by 2020. In 2020, China's refractory materials will have longer life, more energy saving, no pollution and more functional products. The products meet the needs of the national economy such as metallurgy, building materials, chemical industry and emerging industries, and increase the technological content of export products.
