PRODUCTION OF STEEL WIRE FOR ARC WELDING

摘要

PURPOSE: To prevent the contamination of a water-soluble lubricant and to obtain a process for producing a steel wire for arc welding having good feedability by subjecting this steel wire to dry process drawing with a lubricant prepd. by mixing a wet process lubricant with a dry process lubricant, then to wet process drawing in the water-soluble lubricant and adjusting the deposition of the lubricants sticking thereto. CONSTITUTION: The arc welding wire is drawn with the lubricant prepd. by mixing the wet process lubricant adjusted to 5 to 15wt.% in volatile content of a dispersant of animal and vegetable oils or synthetic oil with the dry process lubricant after a plating stage at the time of producing the arc welding wire. The wet process lubricant is prepd. by mixing one kind or two kinds of molybdenum disulfide and tungsten disulfide at 5 to 50wt.% with one or >=2 kinds of fatty acids having >=50 deg.C m.p., the ester of monohydric or dihydric alcohol of the fatty acids and petroleum wax. Next, the arc welding wire is subjected to the wet process drawing in the water-soluble lubricant and the amt. of the lubricant to be adhered is adjusted to 0.10 to 0.80g per 10kg wire.
