摘要： A process and apparatus for coating only one side of a metal strip with a molten metal, by continuously conveying a cleaned and heated strip of metal through a protective gas atmosphere above the level of a melting bath of the molten metal. The metal strip is supported on a reverse side thereof in the area of contact with the molten metal, and with the obverse side of the strip out of contact with the bath itself. The molten metal is conveyed by means of a scoop roller towards the supported area of the strip and only the scoop roller is immersed in the melting bath and only for a part of its surface area. The apparatus includes a container adapted to be filled with the molten metal to form the melting bath, a protective hood with a sluice type of inlet and outlet covering the container to maintain an atmosphere of protective gas thereover, and a supporting and deflection roller arranged under the hood above the level of the melting bath which cooperates with the scoop roller arranged below the supporting and deflection roller for together therewith conveying the metal strip through the melting bath. The scoop roller together with the supporting and deflection roller form an adjustable slot for the passage therethrough of the metal strip to be coated.
