Steel Refractories and Technological Progress

Refractories high temperature industrial service base materials to white fused alumina as raw material, in many high-temperature industrial, steel industry is the most important fire-resistant users, fire-resistant materials in the steel industry accounted for 65% to 70% of the total use. For the refractory steel industry varieties, quality and quantity of demand, in the refractory industry technology development has played a guiding role.
The production of our fireproof materials has been ranked first. In 2009, 1359 fire-resistant enterprises above the scale of 2276 statistics, China's manufacturers, has become a real sense of the first million tons of fire-proof material production.
"15" significant progress in China's refractory technology
In the "Tenth Five-Year" period, China's refractory industry structural adjustment, technological progress significantly strains:
Modern large-scale iron and steel enterprises important refractory products in the country has been basically self-sufficient and the annual refractory raw materials and refractory products exports. Refractory products in 2010 the total exports of 153 million tons. This is a very outstanding achievement, since the reform and opening up in the early 1980s, more than 95% of these important products imported from abroad. The service life of important refractory has been greatly improved, such as: Al2O3 - SiC material for iron blast furnace - high - quality C - trough pouring material capacity of more than 15 million tons, large and medium blast furnace life has been more than 10 years, the highest 1400 Years. Of the oxygen top-blow converter life of more than 50 furnace, furnace technology, slag splashing furnace, furnace hundreds of thousands of furnace, large and medium and small ladle life has reached 200 furnace.
Metallurgy refractory materials research and development of new technologies has made gratifying achievements.
Such as: thin slab continuous casting external immersion nozzle,...
