Title:
めっき付着量制御装置および制御方法
Document Type and Number:
Japanese Patent JP7168444
Kind Code:
B2
Abstract:
To perform a control by reflecting various guarantee standards determined for every steel plate, prevent adhesion of excessive plating, improve a yield and secure a quality of a raw material by performing a control such that plating adhesion amount lower limit shortage does not occur in a range that the standard is satisfied.SOLUTION: A plating adhesion amount control device 100 calculates a lower limit cracking risk of a plating adhesion amount corresponding to a guarantee standard of a steel plate by a preset control performed prior to processing the steel plate, and a feedback control performed during the steel plate processing. In the preset control, a plating adhesion amount target value is corrected using a value corresponding to a risk. In the feedback control, a control is performed so that the plating adhesion amount becomes lower than the lower limit by correcting an adhesion amount deviation. A risk that the plating adhesion amount becomes lower than the lower limit is calculated for every guarantee standard. Therefore, plating is not excessively adhered due to unnecessary correction, so that a plating raw material can be saved.SELECTED DRAWING: Figure 17
