The product function of refractory magnesia iron brick

The product function of refractory magnesia iron brick

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, magnesia chrome brick prices, military industry, etc. They are the basic materials for the production operation and technological development of the above-mentioned industries. It plays an important role in the development of high-temperature industrial production. Ladle magnesia carbon brick

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%, and the production and sales volume of refractories was the first in the world.

From 2001 to 2010, the output of refractory raw materials and products increased steadily, of which the output of refractory products 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, which was 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, achieving sales revenue of 337.779 billion yuan and 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, which are high-grade refractory raw materials, have become less and less, and resource conservation and comprehensive utilization of resources have become urgent tasks.

Song Zhenyu believes that the refractory industry guides raw material mines to organize scientific mining and optimize and comprehensive utilization of resources. This is the homogenization of minerals of different grades. Indiscriminate mining and digging will gradually promote the more rational use of resources, so that limited resources can play a limited 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, with magnesite reserves and a large exporter of graphite, and its 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 saving and emission reduction is difficult.

With the "Twelfth Five-Year" period, China is speeding up the elimination of backward and consuming capacity. The industry will focus on the development and promotion of new energy-saving furnaces, comprehensive energy-saving technologies, energy management, emission control of "three wastes" and recycling of "three wastes" Use 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 to meet the needs of national economic development such as metallurgy, building materials, chemicals, and emerging industries, and to increase the technical content of export products.
