Preparation method of guitar string steel wires

Abstract

The present invention discloses a preparation method of the guitar string steel wires. The preparation method comprises the following concrete steps of (1) preparing a raw material, wherein the raw material is a wire rod; (2) peeling, immersing the wire rod in a pickling tank, removing an oxidation film on the surface of the wire rod by the chemical reaction, and then washing to clear the residualattachments at pickling; (3) using a drying case to dry the wire rod and removing the moisture; (4) carrying out the thermoplastic processing on the wire rod in a roller kiln to improve the plasticity of the wire rod; (5) cold-drawing the wire rod into the steel wires having the sizes needed by the strings; (6) coating a film, and immersing the steel wires in the tin to obtain a layer of protection film; (7) air drying the steel wires, and then packaging and storing. By the above mode, the preparation method of the present invention enables the extensibility and the elasticity of the steel wires to be improved effectively, after immersing in the tin, and coating a layer of protection film, the external corrosion is reduced, and the usage time is prolonged. Meanwhile, the steel wires havethe bright appearances and the smooth hand feeling, by a unique thermoplastic technology, the quality and the performances of the steel wires are improved, and when the steel wires are used as the strings, the tuning is fast, the pitch is stable and the tone quality is clear.

Description

technical field [0001] The invention relates to the field of strings, in particular to a method for preparing steel wires for guitar strings. Background technique [0002] There are two types of guitar strings. The alto and the treble are both bare strings (that is, a special steel wire with good strength and toughness. The bass strings are wound strings (copper wires are wrapped around the steel wires, the effect is is to use the shortest strings to achieve the low frequency we need). At present, most of the guitar strings used in the market use medium carbon steel wires as the main body, but medium carbon steel has a lower The loss is large, and the service life is relatively short, and the production cost of high-carbon steel and ultra-high carbon steel is too high as a string because it is difficult to prepare. [0003] How to design a preparation process for high-strength guitar strings, using ultra-high carbon steel, reduce production costs, and improve string strengt...

Problems solved by technology

At present, most of the guitar strings used in the market use medium carbon steel wire as the main body. However, compared with high carbon steel and ultra-high carbon steel, medium carbon steel has greater loss and a relatively shorter service life, while high carbon steel and ultra-high carbon steel have a relatively short service life. Ultra-high carbon steel is too expensive to manufacture as strings due to the difficulty of preparation
