Abstract

The present invention relates to a sawtooth metal wire for producing all-steel sawtooth card clothing of a roller or carding element of a spinning device. The sawtooth metal wire has an elongated base part area and an adjacent tooth part area. Teeth are formed by cutting, and each tooth comprises a tooth face, a tooth back, and two side faces. A tooth gap is arranged between the tooth back and the tooth face of every two teeth arranged adjacently in the front-back direction. The sawtooth metal wire is made of alloy steel composed of carbon, silicon, manganese, and chromium and is characterized in that the teeth of the sawtooth metal wire is produced by processing a shaped metal wire and at least partially curing the metal wire. The alloy steel is composed of, by weight ratio, 0.93-1.10% of carbon, 0.15-0.35% of silicon, 0.20-0.45% of manganese, and 1.35-1.60% of chromium; and the alloy steel do not contain vanadium or tungsten. Therefore, the sawtooth metal wire is highly tolerant to wearing and is smooth in surface.

Description

[0001] This application is a divisional application of an invention patent application named "serrated metal wire for producing all-steel sawtooth card clothing" with an application date of June 11, 2008 and an application number of 200810109952.1. Technical field: [0002] The invention relates to serrated wires for the production of all-steel serrated clothings for flat or roller cards, made of alloy steel containing carbon, silicon, manganese or chromium. Background technique: [0003] A known card clothing (DE2222918A) is made of an alloy with the following composition: [0004] 0.3-2.0% carbon by weight, [0005] 0.05-2.5% silicon by weight, [0006] 0.05-2.0% manganese by weight, and [0007] 0.01-2.0% by weight vanadium, [0008] The alloy is a vanadium steel in which vanadium is an essential element. Vanadium raises the transformation point and thus the hardness and annealing temperature and suppresses the susceptibility to overheating. Vanadium can be replaced ...
