PRODUCTION OF FLUX CORED WIRE FOR STAINLESS STEEL

摘要

PURPOSE: To obtain a process for producing a flux cored wire for stainless steels which is good in productivity and uniform in flux filling rate in production of the flux cored wire for stainless steels in which drawing and heat treatment are repeated. CONSTITUTION: This flux cared wire for stainless steels is produced by filling a flux contg. >=50% metallic powder in a stainless steel pipe at 10 to 30% by the weight of the wire, then subjecting this pipe to drawing and rolling at a reduction of area of >=10% with a roll rolling and drawing machine after the heat treatment. The reduction of area is expressed by the following equation: reduction of area (%)=[1-(the sectional area of the wire after drawing/the sectional area of the wire before drawing)]×100.
