At device null specified band speed in order to administer metal plating to method and the band steel which decrease the coefficient of friction of the belt-shaped

摘要

PROBLEM TO BE SOLVED: To provide a method and a device for lowering the coefficient of friction of the surface of metal bands with a coating, especially of tin-plated or chromium-plated steel bands, which are passed through a coating installation at a band speed.;SOLUTION: The invention provides a method for lowering the coefficient of friction of the surface of plated metal strips, especially of tin-plated or chromium-plated steel strip, which are passed through a plating apparatus at a prescribed strip speed. The method is characterized by spraying an aqueous surfactant solution on the metal strip moving at the above strip speed after the plating process to thereby enable reduction of the friction coefficient of the surface of plated metal strips. The invention further provides a device for applying a metal plating onto a steel strip, especially in a strip tin-plating or chromium-plating device.;COPYRIGHT: (C)2007,JPO&INPIT
