一、宽带钢精轧机前切头飞剪的使用情况目前,武钢1700宽带钢连轧机精轧机前的转鼓式切头飞剪,具有结构简单,使用、维护、调整、更换剪刃方便及造价低等优点,所以,以前建成的宽带钢连轧机精轧机组前的切头飞剪绝大部分都采用转鼓型。就是日本広畑制铁所1984年8月建成的最现代化的热轧带钢厂也仍然采用转鼓式切头飞剪。武钢1700连轧精轧机机组前的切头飞剪,从1978年12月开工到1984年11月已运行了6年,它的各活动件均有不同程度的磨损。由于轧件施加给上下剪刃的水平推力,使飞
First, the wide-band mill finishing before the first flying shears at present, Wuhan Iron and Steel 1700 wide strip mill rolling drum before the cut-head flying shear, with simple structure, use, maintenance, adjustment, easy to replace the blade and the cost Low, so, before the completion of the mill before the completion of the first group of high-speed strip mill rolling shear most of the use of rotary drum type. That is, the most modern hot-strip mills built by Japan’s Sakai Iron Works in August 1984 are still using rotary drum shear cutters. The cutting and shearing of the front of WISCO 1700 tandem mill was started from December 1978 to November 1984 and has been running for 6 years. All the moving parts of it have different degrees of wear and tear. Due to the rolling force applied to the upper and lower blade horizontal thrust, so fly
