一、十年来我国水平连铸技术取得重大进展 “六五”期间共有4个单位同时开发水平连铸技术,首钢钢研究所和山西冶金研究所合作,最早生产出我国第一支水平连铸无缝管坯;北京钢研总院和大连钢厂合作,按国家重点节能科研项目要求,先在总院进行特殊纲管坯一流中间试验(以下称中试),成功后迁去现场再加一流进行工业性试验(以厂称工试);上海钢铁工艺研究所在黄山基地进行不锈钢管坯中试;以马钢钢研所为首的国家科技攻关组先在马
In the last ten years, great progress has been made in horizontal continuous casting technology in our country. During the “Sixth Five-Year Plan” period, a total of four units developed horizontal continuous casting technology at the same time. Shougang Institute of Steel cooperated with Shanxi Institute of Metallurgy to produce the first horizontal continuous casting Seamless Steel Tube Billet; Beijing Steel Research Institute and Dalian Steel Works, according to the national key energy-saving scientific research project requirements, first in the General Assembly for special tube billet first-class intermediate test (hereinafter referred to as pilot), after the success of moving to the scene plus first-class Industrial test (factory workers test); Shanghai Institute of Iron and Steel Technology in the base of Huangshan stainless steel tube Pilot; Maanshan Iron and Steel Institute headed by the national science and technology research group first horse
