According to incomplete statistics, there are about 2,000 refractory enterprises including collective enterprises in the country. In the past ten years, township and village enterprises have sprung up. There are more than 120 small and medium refractory enterprises in Henan Province, producing various refractory raw materials and refractory bricks. In 1988, the output of township enterprises was 425,700 tons, accounting for 49.96% of the province's output.
The distribution of refractory companies in my country is geographically close to steel production bases and refractory raw materials bases. In East China, Shandong Province, the refractory raw material producing area, has the highest output, accounting for about 46% of this region; Henan and Shanxi are well-known refractory raw material producing areas, and their output accounts for 52 to 55% and more than 60% of the region, respectively.
Aluminum-carbon immersion nozzles are concentrated in Refractory Plant. In 1988, the output of this plant accounted for 80.3% of the country total output. High-quality skateboard bricks were concentrated in Shanghai and the Wuxi Taihu Refractory Plant near Shanghai; magnesia and magnesia bricks were concentrated in Liaoning. In the northwest and southwest regions lacking rhodolite resources, consider the development of dolomite, the development of magnesia dolomite bricks, dolomite bricks, or magnesia resources in salt lakes. In short, Located in the hinterland of the Central Plains, Henan Province is rich in mineral resources, which provides a unique advantage for the production of high-quality refractory materials. According to statistics, from January to December 2014, the output of refractory products in Henan Province was 49.849 million tons, accounting for 42.62% of the country's total output, an increase of 11.88% year-on-year. The refractory industry has become one of the advantageous industries in Henan Province and has a pivotal position in the national economy of Henan Province. The advantages also include the advantages of Henan refractories: abundant resources, low cost, good quality, flexible sales, and convenient transportation.
In addition to resource advantages, Henan also has significant advantages in the research and development of refractory materials. The Luoyang Institute of Refractory Materials and the Institute of High Temperature Materials of Zhengzhou University in the province are the top comprehensive research institutions of refractory materials in China. They have strong scientific research and development capabilities and provide a solid guarantee for the development of the refractory industry in Henan Province.
