某钢厂从国外引进一套4流连铸机和一条小型连轧生产线,它们呈垂直布置。按传统的转运方式,须先将热钢坯送入冷床,再经推钢机用弧形辊道或转盘送入轧制线。由于这种转运方式的移动路线长,钢坯温降较大,表面生成的氧化铁皮较多,不仅增加了材料的消耗量,而且在进入轧机前还须进行补偿加热,使能耗增加。 为了消化、改造这条生产线,我们承担了“七五”国家科技攻关项目“连铸连轧技术”中的子课题——连铸坯的快速输送及补偿加热技术。为了探索在连铸连轧线间采用专用机械手,实现坯料快速 A steel mill imported a set of 4-strand caster and a small continuous rolling line from abroad, which were arranged vertically. According to the traditional mode of transport, the hot billet must first be sent to the cooling bed, and then sent by rolling machine with arc roller or turntable into the rolling line. Due to the long moving route of this transport mode, the temperature drop of the billet is large and there is more oxide scale on the surface, which not only increases the material consumption, but also compensates heating before entering the rolling mill so as to increase the energy consumption. In order to digest and transform this production line, we undertook the sub-project of “Continuous Casting and Rolling Technology” in the “Seventh Five-Year” national scientific and technological project - rapid conveyance of continuous casting slab and compensation heating technology. In order to explore the use of special robots in the continuous casting and rolling lines to achieve rapid billet
