Abstract
A uniform plating treatment is carried out on one-side of a steel strip in that the strip is travelled horizontally over a still surface of a plating bath while the plating bath is jetted onto the one-side of the strip, and the one-side is positively given on its edges a plating flow running in width of the strip outwardly from the edges and the other part except the edges is given the plating flow running in length of the strip.
Claims22
In an apparatus for dip plating one side of a steel strip, comprising a bath for holding plating material with a surface, said steel strip being horizontally movable over said surface of said bath, the improvement wherein said bath has a substantially still surface and wherein comprising a plurality of jetting nozzles disposed with their ends above said still surface and with a space between said ends of said nozzles and said one side of said strip, and pump means for pumping plating material through said nozzle ends onto said one side of said strip;
- and wherein said jetting nozzles comprise a center nozzle disposed in the width dimension of said strip, and at least one edge nozzle disposed in the length dimension of said strip, and wherein said center nozzle and said at least one edge nozzle are integral and in a T shape.
In an apparatus for dip plating one side of a steel strip, comprising a bath for holding plating material with a surface, said steel strip being horizontally movable over said surface of said bath, the improvement wherein said bath surface is a substantially still surface, and wherein comprising a plurality of jetting nozzles disposed with their ends above said still surface of said bath and with a space between said ends of said nozzles and said one side of said strip, and pump means for pumping said plating material through said nozzle ends onto said one side of said strip, and wherein said jetting nozzles comprise a center nozzle disposed in the width dimension of said strip and at least one edge nozzle disposed in the length dimension of said strip, and wherein said center nozzle and said at least one edge nozzle are integral and in a L shape.
In an apparatus for dip plating one side of a steel strip, comprising a bath for holding plating material with a surface, said steel strip being horizontally movable over said surface, the improvement wherein said surface is a substantially still surface, and wherein comprising a plurality of jetting nozzles disposed with their ends above said still surface of said bath with a space between said nozzle ends and said one side of said strip, elongated plates on said jetting nozzles for guiding said plating material, and pump means for pumping plating material through each of said nozzles onto said one side of said strip, and wherein said jetting nozzles comprise a center nozzle and at least one edge nozzle, said center nozzle provided with said plates elongated in length dimension of said strip, and said edge nozzle provided with said plates elongated outwardly in the width dimension of said strip, and wherein further comprising a weir plate disposed on a circumferential edge without any exit of said plates elongated on said edge nozzle.
In an apparatus for dip plating one side of a steel strip comprising a bath for holding plating material, and said steel strip being horizontally movable over the surface of said bath, the improvement wherein said surface is substantially a still surface, and wherein comprising a plurality of jetting nozzles disposed with their nozzle ends a predetermined distance above said still surface of said bath, elongated plates on said jetting nozzles for guiding said plating material, with a space between said plates on said nozzles and said one side of said strip, and pump means for pumping plating material through each of said nozzles onto said one side of said strip, and wherein said jetting nozzles comprise a center nozzle and at least one edge nozzle, said center nozzle being provided with said plates elongated in the length dimension of said strip, and nozzle mask slidable in the width dimension of said strip on both sides of an end of said nozzles.
An apparatus for dip plating of one side of a steel strip, comprising a bath of plating material with a substantially still surface, a plurality of jetting nozzles having their ends positioned at a predetermined distance above said still surface of said plating bath, wherein said strip is horizontally movable above said still surface and at a predetermined distance from said ends of said nozzles, and pump means for pumping said plating material onto said one side of said strip, wherein said jetting nozzles comprise a center nozzle disposed in the width dimension of said strip, and at least one edge nozzle disposed in the length dimension of said strip.
An apparatus for dip plating one side of a steel strip, comprising a plating bath having a substantially still surface, a plurality of jetting nozzles having ends positioned at a predetermined distance above said still surface of said bath, elongated plates on said jetting nozzles for guiding said plating material, wherein said strip is horizontally movable above said still surface of said bath at a predetermined distance between said one side of said strip and said plates on said nozzles, and pump means for pumping said plating material onto said one side of said strip, wherein said jetting nozzles comprise a center nozzle and at least one edge nozzle, said center nozzle being provided with said plates elongated in the length dimension of said strip, and said edge nozzle being provided with said plates elongated outwardly along the width dimension of said strip.
