大冶钢厂将横列式轧制 (4 3 0轧机 )改造为半连轧生产线 ,生产线前面的轧机、飞剪、冷床由北京钢铁总院设计 ,大冶钢厂负责横移输送链和堆垛机的改进设计。横移输送链设计成三段 ,每段长7m,由两台功率为 1 5k W的电机驱动 ,移动速度为 4 6～ 1 3 0 mm/s,变频调速。第一段输送链 Daye Steel Mill will be rolling (403 rolling mill) into a semi-continuous rolling production line, rolling mill in front of the production line, flying shear, cold bed designed by the Beijing Iron and Steel Institute, Daye Steel is responsible for the transfer conveyor chain and pile Improved design of crane. The cross conveyor chain is designed in three sections, each 7 m long, driven by two motors of 15kW and moving speeds of 46 to 130 mm / s. The first section of the conveyor chain
