一炼轧厂是由原三炼钢厂、热轧薄板厂于2007年12月整合而成。原三炼钢厂始建于1975年,原为3座15吨小转炉,经过几代人的艰苦创业和技术改造,现发展壮大为拥有3座100吨级以上顶底复吹转炉、2台6机6流小方坯连铸机的现代化大工厂。原热轧薄板厂是被列为湖南省“十五”期间推进工业化进程十大标志性工程之首的国家重点工程,于2004年2月建成投产,创造了同类型CSP生产线达产达效速度最快等多项世界纪录。
A refining mill is the original three steel mills, hot-rolled sheet mills in December 2007 from integration. The original three steel mill was built in 1975, the original three 15 tons of small converter, after several generations of arduous pioneering and technological transformation, is now developing and expanding to have three more than 100 tons top and bottom blowing converter, 2 6 machine 6 stream billet caster modern large factory. The former hot-rolled sheet mill is the national key project listed as one of the top ten landmark projects for promoting industrialization in Hunan Province during the “Tenth Five-Year Plan” period. The hot rolled sheet mill was put into operation in February 2004 and has reached the production output of the same type of CSP production line Fastest speed and many other world records.
