Problems solved by technology

[0003] Ordinary pigtail rings are mostly made of low-carbon steel, which has certain strength and hardness, but its oxidation resistance and corrosion resistance are generally poor in humid and hot environments, and its service life is affected; for this reason, people Most of the alloying elements are added to the low-carbon steel treatment, such as nickel, chromium, cobalt, titanium, etc. The process of adding these alloying elements is complicated, and the content is high, and the preparation cost is high, so it is not suitable for mass production of pigtail rings

Embodiment

[0020] Concrete preparation steps are as follows:

[0021] a) Preparation of metal elbows, this step mainly includes preparation, mixing, melting, casting, annealing, grinding, bending, normalizing and other processes; in the preparation process, the ingredients and weight percentages of raw materials are: C 0.15%-0.2 %, Fe 70%-85%, Cr 6%-8.5%, Al 8%-10%, Ni 1.5%-2.4%, Mo 0.8%-1.2%, W 0.6%-0.8% and V 1.2%-1.4% ;In the mixing process, the raw materials are mixed on the ball mill, and the particle size of the mixed material after grinding is 150-250 mesh; in the melting process, the melting temperature is controlled between 1550 ° C and 1600 ° C, and a small amount of metal exists in the form of particles. It can effectively improve the strength and wear resistance of the material; in the casting process, the casting temperature of the alloy is controlled between 1560°C and 1620°C; in the annealing process, the casting is annealed to eliminate casting stress and improve the plas...

Abstract

The invention discloses a production method of a novel pigtail coil. The production method mainly comprises the following steps of: (a) preparing a metal elbow; (b) carbonizing; (c) producing a screw; (d) welding and forming; and (e) carrying out stress relief annealing. The production method is reasonable in work procedure arrangement, simple and convenient in production process and moderate in cost; and according to the pigtail coil produced by using the production method, special efficacies of various alloy elements in the pigtail coil can be fully played and the oxidation resistance and the corrosion resistance of a material can be effectively improved and the application field of the pigtail coil is widened.

Description

technical field [0001] The invention relates to a preparation method of a pigtail ring, in particular to a preparation method of a novel pigtail ring with excellent comprehensive performance, and belongs to the technical field of textile equipment. Background technique [0002] The pigtail ring is a common accessory in textile machinery. Its main function is to lead the thread through the thread to ensure that the fiber thread slides smoothly on its surface. Its main performance requirement is to reduce the resistance of the fiber thread when it slides on its surface and reduce the wear of the fiber thread; At the same time, it must have good strength and impact resistance, and it must have good oxidation resistance and corrosion resistance in humid and hot environments. [0003] Ordinary pigtail rings are mostly made of low-carbon steel, which has certain strength and hardness, but its oxidation resistance and corrosion resistance are generally poor in humid and hot environ...
