Abstract
An installation for the hardened galvanization of a continuously-moving rolled steel strip, includes a coating tank receiving a liquid metal mixture containing, for example, zinc and aluminum to be deposited on the strip which is immersed in the mixture. The liquid mixture is permanently circulated between the coating tank and a preparation device, in which the temperature of the liquid mixture is deliberately lowered in order to reduce an iron solubility threshold and is sufficiently high for initiating fusion of at least one ingot containing a zinc-aluminum Zn—Al alloy in a so-called fusion zone of the preparation device, in an amount necessary to compensate for the liquid mixture used for deposition on the strip. The installation includes a loop for circulating the liquid mixture that is thermally optimized.
