STEEL PLATE ROLLING DEVICE WITH A WORKING ROLL WITH ELECTROMAGNET CAPABLE OF REINFORCING ROLLING REDUCTION FORCE USING ELECTROMAGNET

摘要

PURPOSE: A steel plate rolling device with a working roll with electromagnet is provided to roll a steel plate with stronger rolling reduction force using magnetic force as well as fluid pressure when the steel plate is rolled.;CONSTITUTION: A steel plate rolling device with working roll with electromagnet comprises a pair of working rolls(210), a pair of backup rolls(220), a plurality of electromagnets(215), and a control unit. The working rolls make contact with both surfaces of a steel plate(10). The backup rolls supply driving force and rolling reduction force to the working rolls. The electromagnets are uniformly arranged on the working rolls and their magnetic force is individually controlled. The control unit controls polarity and operation of the electromagnets depending on the rotation of the working roll.;COPYRIGHT KIPO 2012
