Converter Tapping-hole Filling Material

Refractory materials are used in various fields of national economy such as steel, non-ferrous metals, glass, cement, ceramics, petrochemicals, machinery, boilers, light industry, electric power, military industry, etc. Electric furnace magnesia carbon bricks are essential to ensure the production and operation of the above-mentioned industries and technological development. The basic materials play an irreplaceable role in the development of high temperature industrial production.

Since 2001, under the strong development of high-temperature development 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 producer and exporter of refractory materials in the world. In 2011, China's refractory production accounted for about 65% of the world's total, and production and sales ranked the world's refractory materials.

From 2001 to 2010, the output of refractory raw materials and products increased steadily, of which the end of the “Tenth Five-Year Plan” was about twice that of 2001; in 2010, the output of refractory products nationwide reached 2,080,600 tons, about three times that of the end of the “Tenth Five-Year Plan”. As of 2011, China's refractory industry has a total of 1917 enterprises above designated size, employing more than 300,000 people, achieving sales income of 337.679 billion yuan and achieving a sales profit of 47.737 billion yuan.
