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.
