Problems solved by technology

However, the lubricant of this invention contains synthetic resin as the main component, and cannot stably exhibit sufficient lubricating properties under severe processing conditions.
In addition, although there are descriptions about the lubricity, there is no sufficient description about the case where the wire rods are treated continuously in-line.

Abstract

The invention provides a method for the inline manufacturing of metal wire rod for use in plastic working with excellent lubricity, thereby providing energy, space and time savings, wherein the surface of metal wire rod cleaned by shot blasting, sand blasting, bending, anodic pickling, and cathodic pickling or the like for 20 seconds or less; contacted with an aqueous, lubricating-coating formation processing liquid containing inorganic salt and at least one kind of lubricant for 5 seconds or less, and then dried immediately to form a lubricant film with a coating weight of 0.5-20 g / m2 on the surface of said metal rod, all in a continuous inline system.

Description

technical field [0001] The present invention relates to a method for producing an inline metal wire for plastic working that imparts excellent lubricity without subjecting the surface of a metal wire such as steel, stainless steel, titanium, or aluminum to a chemical conversion treatment. More specifically, it relates to forming a film with excellent lubricity in-line without performing a chemical conversion treatment on the surface of metal wires such as steel, stainless steel, titanium, and aluminum during cold plastic processing such as header processing. new method. Background technique [0002] Generally, when plastically processing metal materials such as steel and stainless steel, a lubricating film is formed on the metal surface for the purpose of preventing sintering and scratches caused by the contact between the processed material and the metal of the tool. As such a lubricating coating, there is a type in which a lubricant is physically attached to the metal sur...
