New Development of Refractory Technology in China

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 common silica brick of the varieties, quality and

quantity of demand, in the refractory industry technology development plays a guiding role.

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 are refractory materials 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, refractory material 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.

To the promotion of high temperature industry, refractory material has important significance of saving energy and reducing consumption. Monolithic refractories possess the

advantages of energy saving from production to use. The usage account of monolithic refractories used in industrialized countries have reached more than 50%, at present it is

only 20% ~ 30% in our country, should vigorously develop high performance, energy-saving monolithic refractories, and play a role in high temperature industry.
