Embodiment Construction

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below, obviously, the described embodiments are only some of the embodiments of the present invention, not all of the embodiments.

[0017] A method for preparing wear-resistant and anti-fouling knitting needles, comprising the following steps;

[0018] Step 1: Melting and casting steel ingots; use a certain proportion of metal elements to melt and cast steel ingots, and use the steel ingots cast after melting in an induction furnace as consumable electrodes and place them in the electroslag remelting device for electroslag remelting, and the liquid metal passes through the slag The slag layer of the pool falls into the water-cooled crystallizer below, and then re-solidifies into steel ingots; the specific material ratio of steel ingots is as follows: the mass percentage of C element is 0.8-1.2%, the mass percentage of Si element is 0.1-0.5%, The mass percentage ...

Abstract

The invention relates to the technical field of knitting needle manufacturing, in particular to a production method for an abrasion-resistant anti-fouling knitting needle. A knitting needle steel material is produced through the following steps of steel ingot casting, furnace annealing, steel material quenching and steel material tempering. By controlling the furnace temperature and the temperature rise speed of a steel ingot, the steel ingot can be prevented from generating thermal stress cracks in the heating process, and the temperature of the whole surface of the steel ingot to the core part can be kept uniform through heating and heat preservation, so that the forging shape of the steel ingot can be improved, the cracking tendency of the steel in the forging process is prevented, thestrength and toughness of the steel are improved, and meanwhile, the wear resistance of the knitting needle is improved.

Description

technical field [0001] The invention relates to the technical field of knitting needle manufacturing, in particular to a preparation method for wear-resistant and anti-fouling knitting needles. Background technique [0002] Knitting needles are important working parts of various knitting machines, and their quality level and level are reflected in both performance and life. As we all know, there has always been a big gap between domestic knitting needles and foreign advanced levels. In addition to low manufacturing precision, the raw materials used for knitting needles, heat treatment and surface treatment equipment, and various technologies are also important influencing factors. Relatively weak. With the rapid development of the knitting industry, many domestic knitting manufacturers have successively imported some knitting machines such as circular weft knitting machines, warp biasing machines, computerized flat knitting machines, and automatic hosiery machines; The str...
