Abstract: The large-volume are fumace 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 mmx130 mm and 350 mm×470 mm and alloy steel slab size was between 1030 mm x160 mm and 1900 mm×300 mm. The continuous casting production in percent of domestic special steel inereased 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.
