There are more than 1100 refractory raw materials and refractory products enterprises in Henan, with about 250000 employees.
There are more than 1100 refractory raw materials and refractory products enterprises in Henan, with about 250000 employees. In 2013, the output of refractory raw materials and products is about 26.5 million tons, accounting for 48% of the national total, which has become a large production base of refractory materials. Relying on the technical support of colleges and universities, scientific research institutions, academicians, professors, etc. inside and outside the province, relying on the R & D platform of the enterprise, the province has established its unique resources and talent advantages, especially through the cooperation of production, learning and research this year, a large number of scientific and technological innovation achievements have been achieved, more than 100 achievements have been awarded the national, provincial or municipal science and technology progress award, or more than 1000 national inventions and utility models. In the past 10 years, remarkable achievements have been made in the structural adjustment of refractory varieties in Henan Province. A large number of high-tech products have been developed and 41 high-tech enterprises have been established.
Alumina silica refractories are the leading products in Henan Province. Current situation of aluminum silicon raw materials in Henan Province: up to now, 72 refractory clay mining areas have been identified with a total storage capacity of 2677.21 million tons, with a total storage capacity of 30883000 tons. Among them, 16 high aluminum clay mining areas have been identified with a total storage capacity of 51.871 million tons, with a total storage capacity of 72.299 million tons. There are 31 hard clay mining areas identified, with a total storage capacity of 190.711 million tons and 207.347 million tons; 6 soft clay mining areas identified, with a total storage capacity of 25.1339 million tons and 29.247 million tons. Among the identified resources of refractory clay, high alumina clay accounts for 19%, soft clay for 9% and hard clay for 72%. In the identified high alumina clay mining area, 70% of the ore quality belongs to the middle and low grade, and only the grade Al2O3 content in the four mining areas of JIAJIAWA, DUJIAGOU, Baofeng bianzhuang and Dengfeng Zhuangtou is more than 65%
