Abstract: The annual output of steel melted by converter was nearly up to 190 million tons in China in 2003, which was 85.2% of annual output of steel in China and was 25% of world converter steel output in that year. The number of 50 ~ 300 t converters increased to 134 sets in 2003 from 75 sets in 2001, and the process and technology of converter steelmaking further optimized. the new grade steel and quality steel melted by converter increased very fast including lo w alloy steel, atmospheric corrosion resistant steel, TRIP(transformation induced plasticity steel, and special steel such as alloy structure steel, gear steel, bearing steel and steel for boiler. In the future the converter steel production mainly depended on potential- tapping and revamping of excellent iron and steel producers to further improve technology and equipment, expend ·steel grade range, increase quality of steel, reduce consumption and improve environment.

摘要： 2003年我国转炉钢产量已接近1.9亿t,占我国钢产量的85.2%,约占世界转炉钢的25%。50～300t转炉由2001年的75座增至2003年的134座,工艺技术进一步优化。我国转炉冶炼新钢种和优质钢种增长迅速,其中包括低合金、耐候钢、TRIP(相变诱发塑性)钢以及合金结构钢、齿轮钢、轴承钢、锅炉用钢等特殊钢。今后转炉钢的增长主要是对条件较好转炉钢厂挖潜改造,进一步提高装备水平、扩大品种、提高质量以及降低消耗,改善环境。
