During the use of the converter lining, the structure of the furnace lining is easily damaged due to the long-term high temperature state of the refractory material on the charging side, the steel side and the bottom of the furnace, and the repeated erosion of the mechanical force impact and slag and molten steel, and the loss caused by the rapid temperature change. At the same time, in order to reduce the cost of steelmaking, the steel mills have greatly increased the use of scrap steel in the converter, increasing the mechanical damage to the refractory material of the front large surface furnace lining, and at the same time, the serious peroxide phenomenon in the furnace has accelerated the erosion of the lining brick, making the life of the converter drop sharply.

Refractors Industry Optimization and Reorganization in 2015
Since 2000, China's refractory industry has entered the fastest stage of development, and is now a major producer and exporter of refractory materials in the world. According to the survey results of the European Federation of refractory manufacturers on the global refractory production in 2011, the global refractory production in 2011 was 42.75 million tons, of which China's refractory production was 29.5 million tons, accounting for 69% of the global production. With the obvious improvement of the stock trend of related companies, the innovation ability and process equipment level of Beijing Lear, the advantage and position of China's refractory industry in the international refractory market has also been greatly improved.
