摘 要：
PURPOSE:To uniformly plate the whole surface of a long-sized band steel in
desired amts. by providing a plated metal amt. meter directly above a wiping nozzle and a crosswise plated metal amt. meter on the downstream side, and feedback-controlling the nozzle pressure and the distance from the band steel based on the measured values at the time of plating the band steel with molten metal.
CONSTITUTION:The band steel 1 is passed through the inside of a molten metal plating bath 2, and the molten metal plating amt. is adjusted by the injection of the gases from the wiping nozzles 3 and 3. The plated metal amt. meter 7 is provided above the nozzle 3, the
measured value is inputted to a feedback controller 12 and a feedback
characteristic compensator 15, the measured value from the crosswise plated metal amt. meter 18 is also inputted to the compensator 15, both

摘 要 附 图：
measured values are compared, and the resulting compensated value is inputted to the controller 12. As a result, the
distance between the wiping nozzle 3 and the band steel 1 and the pressure of the gas injected from the nozzle 3 are
controlled by an adjusting valve 4, and the desired amt. of the plating layer is uniformly formed in the lengthwise and cross wise directions of the band steel 1. 主权项：
