Embodiment 1

[0009] Example 1: (1) Send the high-carbon steel wire rod into the wire drawing machine for one-time drawing, heat and quench the steel wire after one-time drawing to obtain sorbite quenched steel wire, and draw once The heating temperature is 900°C; (2) Send the quenched steel wire that has undergone surface pretreatment into the furnace for heating at a heating temperature of 800°C. The surface pretreatment is drum polishing for 30 minutes, and the drum is filled with polishing solution. Described polishing solution is the chromium oxide micropowder of W0.5 and the paraffin wax solution of 20wt%, sprinkles auxiliary agent to quenched steel wire surface during, and described auxiliary agent comprises the nylon fiber of 15 parts by weight and the titanium dioxide of 5 parts by weight; (3) Take out the quenched steel wire for secondary drawing, and then put it into deionized water at 0°C for quenching.

Embodiment 2

[0010] Example 2: (1) Send the high carbon steel wire rod into the wire drawing machine for one drawing, heat and quench the steel wire after the first drawing to obtain the sorbite quenched steel wire, and draw it once The heating temperature is 950°C; (2), the quenched steel wire that has undergone surface pretreatment is sent into the furnace for heating, and the heating temperature is 900°C. The surface pretreatment is drum polishing for 40 minutes, and the drum is filled with polishing solution. Said polishing solution is the chromium oxide micropowder of W5 and the paraffin wax solution of 20wt%, during which auxiliary agent is sprinkled on the surface of quenched steel wire, said auxiliary agent includes 20 parts by weight of nylon fiber and 15 parts of titanium dioxide; (3 ), take out the quenched steel wire for secondary drawing, and then put it into deionized water at 5°C for quenching.

Embodiment 3

[0011] Example 3: (1) Send the high-carbon steel wire into the wire drawing machine for one-time drawing, heat and quench the steel wire after one-time drawing to obtain sorbite quenched steel wire, and draw once The heating temperature is 920°C; (2), the quenched steel wire that has undergone surface pretreatment is sent into the furnace for heating, and the heating temperature is 850°C. The surface pretreatment is drum polishing for 35 minutes, and the drum is filled with polishing solution. Described polishing solution is the chromium oxide micropowder of W2.5 and the paraffin wax solution of 20wt%, sprinkles auxiliary agent to quenched steel wire surface during, and described auxiliary agent comprises the nylon fiber of 17 parts by weight and the titanium dioxide of 10 parts; (3) Take out the quenched steel wire for secondary drawing, and then put it into deionized water at 3°C ​​for quenching.

Abstract

The invention discloses a musical string preparation method, and the method comprises the following steps: (1), enabling a high-carbon steel wire rod to be put into a wire drawing machine for primary drawing, carrying out the heating, quenching and surface pre-treating of the steel wire after primary drawing, and obtaining a sorbite quenched steel wire; (2), enabling the quenched steel wire after surface pre-treating to be put into a smelting furnace for heating, and scattering an accessory ingredient on the surface of the quenched steel wire, wherein the heating temperature is from 800 DEG C to 900 DEG C, and the accessory ingredient comprises 15-20 parts, by weight, of nylon fiber, and 5-15 parts, by weight, of titanium dioxide; (3), carrying out the secondary drawing of the quenched steel wire, and then putting the quenched steel wire in deionized water at temperature from 0 DEG C to 5 DEG C for cold quenching. The beneficial effects of the invention are that the hardness and toughness of the steel wire are improved to the values suitable for the musical string; nylon fiber is added to wrap the steel wire, so as to shield the interference from the external environment; the method gives consideration to the hand feeling of a user, and prolongs the service life of the musical string.

Description

technical field [0001] The invention relates to the field of musical instrument manufacturing, in particular to a method for preparing strings. Background technique [0002] The string that excites the sound on the stringed instrument, under a certain tension, excites the string to vibrate through friction, flicking, etc., and is amplified by the resonant cavity to obtain the musical tone, which is the most important part of the stringed instrument. Usually made of silk, sheep gut, metal, or filament plastic fibers. Strings are easily corroded and rusted by humid air, or worn out due to long-term use. Generally, if the strings are used for more than 2 hours a day, they need to be replaced every 3 months. Contents of the invention [0003] The technical problem to be solved by the present invention is that the existing strings are prone to rust and wear, and have a short service life. Therefore, a preparation method for strings with a long service life and not easy to rust...
