Processing technique of BS (blue sapphire) traveller used for spinning

Abstract

The invention discloses a processing technique of a BS (blue sapphire) traveller used for spinning. The technological process comprises the following steps: (1), selecting material, taking high quality alloy-steel wires containing chemical elements such as W, V, Ni and Co as raw material; (2), tabletting; (3), annealing; (4), forming; (5), quenching and tempering; (6), polishing; (7), surface diffusion treating, melting the chemical compound with transition elements to diffuse and permeate the chemical compound into the base body of the traveller, allowing the surface of the traveller to be blue; and (8), surface curing and treating. The traveller produced by adopting the processing technique has the characters of good wear resistance, anti-friction quality, corrosion resistance and long service life and the like, can obviously reduce the phenomenon of airiness, flying rings and broken ends, can better satisfy the current spinning development requirement of 'high count, high speed and high efficiency', is particularly suitable for compact spinning and common high-speed ring spinning, and also can meet the requirements of novel materials, such as novel fiber, special fiber, carbon fiber, cotton-like fiber and mixed fiber.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a processing technology of a BS (sapphire) traveler. Background technique [0002] my country is a big textile country, and the textile industry has become an important livelihood industry in our country. With the development of the industry, spinning is developing in the direction of high speed, high count, high density, automation, and compact spinning. In addition to traditional cotton spinning, special fibers, new fibers, carbon fibers, and cotton-like fibers have emerged. Various performance indicators, especially in terms of wear resistance, anti-friction, and corrosion resistance, put forward higher requirements. [0003] The existing traveler uses domestic high-quality carbon structural steel such as 90# and T9A as raw materials, and is made through flattening→annealing→pulling→forming→quenching→tempering→polishing→electroplating. The service life of the traveler is ave...

Problems solved by technology

[0003] The existing traveler uses domestic high-quality carbon structural steel such as 90# and T9A as raw materials, and is made through flattening→annealing→pulling→forming→quenching→tempering→polishing→electroplating. The service life of the traveler is average In 3 to 5 days, the wear resistance, friction reduction and corrosion resistance are low, which cannot meet the requirements of compact spinning and high-speed ring spinning
