摘　　要：20世纪90年代末,国内各主要特殊钢厂先后自建或引进大容量电弧炉和合金钢连铸机,从而推动了我国特殊钢连铸技术的发展。合金钢连铸方坯的规格为1 3 0mm×1 3 0mm至3 50mm×470mm ,板坯为1 0 3 0mm×1 60mm至1 90 0mm×3 0 0mm。国内特殊钢连铸比由1 998年的2 1 .7%增加至2 0 0 3年的61 . 1 7%。根据国外特殊钢企业连铸关键技术和进展,以及对近几年我国特殊钢连铸生产装备、流程、生产量及主要产品质量现状的分析,提出了我国特殊钢连铸技术发展和研究的工作重点。The large-volume arc furnace and continuous caster for alloy steels were built and imported at domestic main special steel works during end of the nineties of 20th century thus to bush the development of continuous casting technology for special steel in China forward. The casting billet size of alloy steel was between 130 mm×130 mm and 350 mm×470 mm and alloy steel slab size was between 1 030 mm×160 mm and 1 900 mm×300 mm. The continuous casting production in percent of domestic special steel increased from 21.7% in 1998 to 61.17% in 2003. According to the key technology and advance of continuous casting at overseas' special steel producer, and based the analysis on production equipment, flow sheet, output of continuous casting billet and quality status of main continuous casting products in china in recent years, the development and research work for special steel continuous casting technology in China are put forward in this paper.
