New Development of Refractory Technology

Refractory material is the base material servicing for high temperature industry. In many high temperatureindustry, iron and steel industry is the most important users of refractory material, the usage account in the ironand steel industry accounts for about 65% ~ 70% of the total. Iron and steel industry to the refractory material ofthe varieties, quality and quantity of demand, in the refractory industry technology development plays a guidingrole.1. Scientific and technological achievementsRefractory industry in China conducts breed structure adjustment, technological progress is remarkableModern large joint use of iron and steel enterprise important refractory product has been basically donedomestic self-sufficiency, and each year there is refractory material and refractory productsexports. Refractory products exports amounted to 1.53 million tons in 2005.This is a very outstandingachievement, because early in the 1980 s reform and opening up, more than 95% these important productsneed to be imported from abroad.
2. Gap and problemsSince China's reform and opening up, go through 20 years of efforts, refractory technology got greatdevelopment in our country, many products have reached or close to international advanced level, has becomea great production nation of refractory material, the total output of refractory material accounted for first in theworld, basically meet the demand of iron and steel industry development. But the whole refractory technologylevel compared with international advanced level, there is still exsisting quite a big gap, especially is the key partof refractory products still need to be imported.
3. Refractory technology development trendOver the past decade, through scientific research, fused cast AZS block science and technology has madegreat progress in our country, solved the localization problem of the refractory material about the introduction ofnew technology in the iron and steel industry, but mostly research technique which is formed by the track type,namely along the introduce, analyze, digestion and absorption, improve the road of innovation.
