Abstract
Abstract The elimination of the conventional pickling and rinse steps following drawing to final gauge in the zinc coating of high carbon steel wire, by the use of water soluble soaps as a drawing lubricant, under controlled conditions, the lubricant and other contaminants being removed as an incident of the final coating operation wherein the drawn wire is passed through a flux bath and then into the zinc coating bath.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
85 words
IN A PROCESS FOR GALVANIZING HIGH CARBON STEEL WIRE WHEREIN THE STEEL WIRE IN NORMALLY CLEAN CONDITION IS SUBJECTED TO A FINAL COLD DRAWING OPERATION PRIOR TO GALVANIZING UTILIZING A WATER-SOLUBLE SOAP, THE IMPROVEMENT WHICH COMPRISES THE STEP OF PASSING THE WIRE DIRECTLY FROM THE FINAL DRAWING OPERATION INTO A ZINC-AMMONIUM CHLORIDE FLUX BATH HAVING A CONCENTRATION OF FROM 8 TO 20 DEGREES BAUME AND THEREAFTER INTO THE ZINC COATING BATH WITH THE ELIMINATION OF A PICKING AND A RINSE STEP FOLLOWING THE FINAL DRAWING.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
15 words
The process claimed in claim 1 wherein the drawing lubricant comprises a water-soluble sodium soap.
Claim 4
Dependent Claim
21 words
The process claimed in claim 2 wherein the flux bath has a normal concentration of from 8 to 12 degrees Baume.
Claim 5
Dependent Claim
43 words
The process claimed in claim 3 wherein the concentration of the flux bath is raised above normal in proportion to the extent of contamination of the wire following drawing, with particular reference to the quantity of residual lubricant carried by the drawn wire.
Claim 6
Dependent Claim
78 words
In a process for galvanizing steel wire in the absence of a heat treatment following the final drawing operation, the final drawing operation utilizing a water-soluble sodium soap as a lubricant, the improvement which comprises the step of introducing the wire into a zinc-ammonium chloride flux bath having a concentration of from 8 to 20 degrees Baume immediately following final drawing and utilizing the fluxing reaction of the bath to clean the wire of contaminants prior to galvanizing.
Claim 7
Dependent Claim
78 words

Claim 8
Dependent Claim
54 words
The process claimed in claim 5 wherein the primary contaminant is residual lubricant, and wherein the normal flux concentration is from 8 to 12 degrees Baume, including the step of adjusting the flux concentration upwardly to as high as 20 degrees Baume in proportion to the quantity of residual lubricant carried by the wire.
