Refractory material is the basis of high temperature industrial maintenance.In many high temperature industry, iron and steel industry is the most important users of refractory materials, using the account of the iron and steel industry accounts for about 65% ~ 70% of the total.Fire-proof material varieties, quality and quantity of iron and steel industry demand, technology development of refractory industry plays a guiding role.
1.Scientific and technological achievements
Refractory industry in China to breed structure adjustment and technology progress is remarkable
Used in combination with modern large-scale iron and steel enterprise important refractory product has been basically completed domestic self-sufficiency, and refractory materials and refractory products are exported every year.Refractory products exports in 1.53 million reached 1.53 million tons.This is a very outstanding achievement, because in the early 1980 s reform and opening up, more than 95% of these important products need to be imported from abroad.
2.Gap and problems
Since China's reform and opening up, after 20 years of efforts, refractory technology got great development in our country, many products have reached or close to international advanced level, has become a great nation in the production of refractory refractory material in the production of the world's first, basically meet the needs of development of iron and steel industry.But the refractory technology compared with international advanced level, there are still a considerable gap, especially the key part of the refractory products also need to import.
