Embodiment Construction

[0038] Preferred embodiments of the present invention will be described in detail below.

[0039] Such as figure 1 As shown, the metal surface treatment method of the present invention includes: the step of washing with water after removing the dirt of the metal material; after washing, when the metal material is drawn through a wire drawing die, in order to improve the lubrication effect, protect the surface of the metal material and A step of carrying (carrier (pick-up)) various lubricants to form an alkali metal salt pretreatment film (hereinafter referred to as "alkali metal salt film") on the surface of the metal material; and a drying step.

[0040] The metal material is made of wire. Wire rod refers to a wire rod (Wire Rod) that is used to manufacture various wires through wire drawing. The wire rod is manufactured by hot rolling to have a diameter of 5.5mm-32mm, and is manufactured as steel wire, iron wire, piano wire by drawing through the hole of the wire drawing d...

Abstract

The invention relates to a metal surface treatment method and a metal surface treatment agent. The method includes the steps of washing with water after removing the dirt of the metal material; after the washing, when the metal material is drawn through a wire drawing die, in order to improve the lubricating effect and protect the the surface of the metal material, the step of forming an alkali metal salt film on the surface of the metal material; and the drying step. The present invention does not cause environmental problems, and enables the surface of the wire to have extensibility, corrosion resistance, and wear resistance.

Description

technical field [0001] The present invention relates to a metal surface treatment method and a metal surface treatment agent. More specifically, it relates to forming a film on a metal surface in order to improve lubricity and extensibility during plastic processing, and includes immersion (Batch System) and continuous operation (Inline System) ) metal surface treatment method and metal surface treatment agent. Background technique [0002] Iron in the metal is easily oxidized in the air and is difficult to store. Therefore, gold plating or chemical conversion treatment is performed in order to protect the metal surface. In chemical conversion treatment, phosphate coating treatment is generally used to form a phosphate coating on the surface of a metal material for the purpose of adhesion of paint, abrasion resistance, lubrication during plastic deformation, electrical insulation, and the like. [0003] The principle of phosphate film treatment is as follows. [0004] 3[Z...
