    • A system for controlling a bar cutter in a steel bar line comprising a rolling length predicting circuit for calculating, on the basis of a scale loss coefficient, a predicted rolling length of a rolling bar material conveyed to the steel bar line, a flying shear cut instructing circuit responsive to the predicted length for determining a cutting length and for operating a flying shear to cut the rolling bar material in accordance therewith, a rolling length measuring circuit for determining an actual rolling length from the cut bar material, and a scale loss coefficient determining circuit for determining the scale loss coefficient based on the actual rolling length so as to correct the predicted rolling length and thereby reduce a cutting error.

    • The wire rolling mill has a plurality of roughing stands, a cropping shears, a finishing block, a coiler with a coiler pipe and a coiler drive including a coiler motor and a coiler gear unit and a delivery conveyor for the finished wire deposited in coils. The wire rolling mill also has a controller with a computer which controls the cropping shears with a predetermined rolling program by a computer shear command. The cropping shears cuts away a cropped length from the rolled wire rod workpiece prior to entry in the finishing block defined in the computer shear command thus producing a wire head to be deposited in coils. The cropped length of the wire is put in line with the position of the coiler. The coiler is provided with a rotation angle position transmitter operating with digital pulses which is connected with the controller and whose angular position corresponds to the coiler pipe positions. The controller combines the computer shear command and the digital pulses by an electronic AND-circuit into a shear positioning command and the cropping shears responds to the shear positioning command.
    • 线材轧机具有多个粗轧机,裁剪机,精整机组,具有卷取机的卷取机和卷取机驱动,其包括卷取机马达和卷取机齿轮组,以及用于卷绕成品的成品丝的输送机。 钢丝轧机还具有带有计算机的控制器,该计算机通过计算机剪切命令以预定的滚动程序控制剪切剪。 裁剪剪切机在进入计算机剪切指令中定义的精加工块之前,从轧制的线材工件上切下一段剪切长度,从而产生一个待卷绕的线头。 线的裁剪长度与卷取机的位置一致。 卷取机设置有旋转角度位置传送器,其与数字脉冲一起操作,数字脉冲与控制器连接,其角位置对应于卷取机管位置。 控制器通过电子AND电路将计算机剪切指令和数字脉冲组合成剪切定位命令,裁剪剪刀响应剪切定位命令。
