| description | Disclosed is a method and an apparatus for rolling control of a thick steel plate. The method for rolling control of a thick steel plate according to the present invention comprises: a step where a control unit determines whether an asymmetry has occurred on a pass line; a step where the control unit calculates a roll gap control quantity when an asymmetry has occurred; a step where the control unit calculates a compensation velocity of top and bottom work rolls in accordance with the roll gap control quantity; and a step where the control unit controls the driving speed of the top and bottom work rolls in accordance with the compensation velocity of the top and bottom work rolls.
본 발명은 후판 압연 제어방법 및 장치가 개시된다. 본 발명의 후판 압연 제어방법은, 제어부가 패스라인의 비대칭성의 발생여부를 판단하는 단계; 제어부가 비대칭성이 발생한 경우 롤갭 조정량을 산출하는 단계; 제어부가 롤갭 조정량에 따른 상하부 워크롤의 보상속도를 산출하는 단계; 및 제어부가 상하부 워크롤의 보상속도에 따라 상하부 워크롤의 구동속도를 조정하는 단계를 포함하는 것을 특징으로 한다. |
