Technical Progress of Domestic Iron Steel Industry and Its Influence on the Development of Refractories

摘要

The quick increase of domestic iron and steel output, the great improvement of steel quality and variety, the importation of advanced equipment and the diminution and elimination of some backward technology and facilities have brought about great influence on the development of refractories. In order to meet the technical progress of iron and steel industry, domestic refractories industry has, in the last decades, concentrated its efforts on the development and production of new Sialon bonded SiC bricks and micropore carbon blocks for giant blast furnaces; new refractories for coke oven and non-coke iron making furnaces; MgO-C bricks for converters and electric conductive refractories for UHP EAF; refractories for slag splashing technology; and the highly technology-intensive refractories for continuous casting facilities. The paper reviews the great change occurred in the industries of iron- and steel-making and refractories during the last decades.
