Method for removing coil in case of stopped continuous casting and hot rolling process by catching coil and coil cutting apparatus used in the method

摘要

The present invention is a hot-rolled coil coil removal process interruption due to jams and how to coil cutting device used therein It relates. A first step for sensing the rolling speed of the hot-rolled steel coil engaging or passing through the detection part 35 of the hot rolling mill thought process 11 according to the present invention, the control unit is detected by the sensing unit 35, the signal and a second step of determining whether or not the jam is received and whether the hot-rolled coil rolled speed value or less; It is configured to include; the coil jams or when the controller determines that the hot-rolled rolling speed more than the set value to determine the extent and location of the coils to be cut a third step of driving a coil cutting device 20. Since the cutting apparatus according to the present invention, the coil 20 has a run-out table 13 and cooling apparatus 15 is provided so as to be movable between a coil portion configured to cut the coil under the control of the controller when a jam occurs, Since the cooling coil to cool the coil without requiring the cutting operation, so it is possible to reduce the amount of time the equipment is stationary as well as the operator does not need to cut up directly over the coil has the advantage that ensure worker safety.
