Method for the manufacture of a metal-coated steel strip. |
摘要 |
<p>A method for the manufacture of a metal-coated steel strip with improved surface structure, wherein the strip is electrolytically coated with one or more metal coatings and the last-applied coating is temporarily melted by supplying heat to the strip (melting-on), is characterized in that the heat supplied to the strip for effecting the melting-on is generated at least in part by an electric current which is at all times non-zero. The heat supplied to effect the melting-on substantially continuously compensates heat loss from the strip to the surroundings during the melting-on, and may for example be generated by electrical resistance heating using only a direct current or using an alternating current on which is superimposed a direct current. The strips produced are free of the so-called woodgrain effect.</p> |
