China is a big exporter of refractories, with few imports and mainly exports. The total annual export trade of refractory raw materials and products is about 3.5 billion US dollars. In recent years, the price of refractory raw materials fluctuates greatly, so does the export trade volume. In 2019, the export volume of China’s refractory products will be 1.6656 million tons, a year-on-year decrease of 7.74%.
Refractories are widely used in steel, building materials, non-ferrous metals, machinery, chemical industry, electric power, light industry and other basic industries, as well as aviation, naval ships, missiles and other military fields. They are structural materials for high-temperature kilns, furnaces and other thermal equipment, and important supporting materials for high-temperature industrial thermal equipment. The scientific progress and technological development of refractory industry play an irreplaceable role in the development of high temperature industry.
