Embodiment 1

[0008] A surface treatment method for the steel ring of a worsted spinning machine, comprising the following steps: subjecting the gold-processed steel to carbonitriding heat treatment, then polishing and cleaning, and then putting it into a nitriding furnace for ion nitriding treatment, nitriding The treated steel is firstly polished, then cleaned and degreased, and then put into the air furnace for preheating. The preheating temperature is 350℃~400℃, and the preheating time is 20~40 minutes. Oxidation in an oxidation furnace, the oxidation temperature is 350°C to 450°C, and the oxidation time is 30 to 40 minutes. Put the oxidized steel ring in the water tank to desalt and clean it, then dry it, and then get the finished product after oil immersion or oil injection.

[0009] The main function of preheating is to dry the moisture on the surface of the workpiece, so that the cold workpiece can be heated up before entering the oxidation furnace, so as to prevent the salt bath sp...

Abstract

The surface treatment method for steel ring of spinning frame comprises: taking nitridation treatment selected from ion-nitridating, salt-bath nitridating or gas soft nitriding to form a compound layer with high hardness, wear-resist and anti-corrosion and an anti-tire diffused layer on the steel ring; then putting the ring into oxidation furnace for oxidation treatment at 350-450Deg to form a black oxide film benefit to its corrosion and wear resistance.

Description

technical field [0001] The invention relates to the processing field of the steel ring of the worsted spinning machine, in particular to a surface treatment method of the steel ring of the worsted spinning machine. Background technique [0002] Steel ring is one of the wearing parts of worsted spinning machine. The steel ring material in my country generally adopts low-carbon steel, and the surface hardness after conventional carbonitriding can only reach about 850Hv, and the hardness is uneven, and the service life is only about one year. Internationally, low-carbon alloy steel is used as the ring material, the hardness after surface treatment can reach more than 1000Hv, and the service life can reach about 3 years. However, low-carbon alloy steel is expensive and costly, and its manufacture involves a wide range of areas, making it difficult to popularize and implement. In addition, the steel ring in the prior art also has the disadvantages of poor wear resistance, corro...
