New Development of Refractory Technology

Refractory material is the base material servicing for high temperature industry. In many high temperature

industry, iron and steel industry is the most important users of refractory material, the usage account in the iron

and steel industry accounts for about 65% ~ 70% of the total. Iron and steel industry to the refractory material of

the varieties, quality and quantity of demand, in the refractory industry technology development plays a guiding


1. Scientific and technological achievements

Refractory industry in China conducts breed structure adjustment, technological progress is remarkable

Modern large joint use of iron and steel enterprise important refractory product has been basically done

domestic self-sufficiency, and each year there is refractory material and refractory products

exports. Refractory products exports amounted to 1.53 million tons in 2005.This is a very outstanding

achievement, because early in the 1980 s reform and opening up, more than 95% these important products

need to be imported from abroad.
2. Gap and problems

Since China's reform and opening up, go through 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 production nation of refractory material, the total output of refractory material accounted for first in the

world, basically meet the demand of iron and steel industry development. But the whole refractory technology

level compared with international advanced level, there is still exsisting quite a big gap, especially is the key part

of refractory products still need to be imported.

3. Refractory technology development trend

Over the past decade, through scientific research, fused cast AZS block science and technology has made

great progress in our country, solved the localization problem of the refractory material about the introduction of

new 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.
