Abstract (en)
[origin: WO9627464A1] The invention concerns a process and a device for the continuous production of sheet metal strips, in particular of steel. A mother strip (1) with a metallically pure surface is drawn through a metal melt bath (14) and the resulting coating is smoothed by rolling immediately after leaving the melt bath. In order to design a process and device for carrying out this operation and facilitating controlled pre-heating of the mother strip to a temperature well above ambient temperature (more specifically, above 200 DEG C) without complex apparatus and without any risk of re-oxidation of the mother strip surface, it is proposed that the mother strip should be introduced into the metal melt bath (14) after being pre-heated to a temperature well above ambient temperature (more specifically, above 200 DEG C); the pre-heating should be done by indirect heat exchange with the melt bath in an oxygen-free environment, and the melt freshly introduced into the melt bath should be at a raised temperature corresponding to the heat loss involved in the pre-heating.
