Equipment and process for the pickling and metallic coating of a metal strip

The present invention describes equipment for the pickling and metallic coating, such as galvanizing, of a continuously running metal strip, successively comprising along the run direction at least a pickling unit, a furnace and a coating unit, and for which the metal strip entering the pickling unit is by default a hot-rolled product. The equipment according to the invention is characterized in that: a rolling mill for elongation/limited reduction of strip thickness, referred to as a skin-pass rolling mill, is positioned between the pickling unit and the furnace; the furnace imposes a heat cycle on the strip that makes it possible to control a restoration of strip structure (that is to say free of strip recrystallization) and imposes, at the outlet of the furnace, a heating of the strip to the temperature that is required at the inlet of the metallic coating unit. A pickling and metallic coating process is also proposed. 本发明描述用于连续行进的金属带的酸洗与例如电镀的金属涂覆的设备，其沿着行进方向依次包括：至少酸洗单元、炉和涂覆单元，并且其中，默认进入所述酸洗单元的金属带是热轧产品。根据本发明
