  • Hot dip coated steel strip having an improved surface appearance and method for production thereof
    Patent number: 11655531
    Abstract: The present invention relates to a method of hot dip coating of flat steel products, comprising a step of stripping the coated steel strip by means of at least one nozzle that emits a stripping gas having a temperature T3 at an angle ? in the direction of the coated steel strip, wherein the angle ?, the distance h between the surface of the melt bath and the lower edge of the nozzle in mm, the temperature of the stripping gas in ° C. and the differential between the temperature T2 of the melt bath and the temperature T1 of the steel strip are in a particular relationship to one another, and to a correspondingly produced hot dip-coated flat steel product.
