Abstract
A method produces a hardened galvanization of a continuously-running rolled steel strip. The strip is immersed in a coating tank containing a bath of a liquid metal mixture, e.g. zinc and aluminum, to be deposited on the strip, and permanently circulated between the coating tank and a preparation device. The temperature of the liquid mixture is deliberately lowered in order to reduce the iron solubility threshold and sufficiently high for initiating, in the preparation device, the fusion of at least one Zn—Al ingot in an amount necessary for compensating for the liquid mixture used for deposition on the strip. The device is implemented so that the circuit for circulating the liquid mixture is thermally optimized.
