Problems solved by technology

However, these wires are sometimes corroded during transport or installation
The iron oxides on the surface of the wire present hard particles, as a result of which corroded carding wires may cause the carding wires to fail during the carding process

Embodiment Construction

[0044] The elongated steel wire can be produced as follows.

[0045] First, an oil-quenched and tempered steel monofilament, a metal bath including an organic solvent and metal particles, and a heating device are provided.

[0046] Oil quenched and tempered steel monofilaments can be produced by drawing wire rod while heat treating and have a metallic structure greater than 96% martensitic.

[0047] first by mechanical descaling and / or by 2 SO 4 Or chemical pickling in HCl solution to clean the wire rod in order to remove the oxides present on the surface. The rods are then rinsed in water and dried. The dried wire rod is then subjected to a first series of dry drawing operations in order to reduce the diameter up to a first intermediate diameter.

[0048] At this first intermediate diameter d1, for example at approximately 2.30 mm to 3.50 mm, the dry-drawn steel monofilament is subjected to a first intermediate heat treatment known as lead-bath quenching. Lead bath quenc...

Abstract

An elongated steel wire is provided, the elongated steel wire comprises a steel filament and a metal coating for corrosion resistance upon the steel filament, the steel filament has a microstructure comprising more than 96% tempered martensite. The elongated steel wire is an environment friend product, and it has good corrosion resistance, abrasion resistance, hardness and strength.

Description

technical field [0001] The present invention relates to an elongated steel wire with a metallic coating for corrosion resistance, and a method for its manufacture. The present invention relates to the use of elongated steel wires with a metallic coating for corrosion resistance as carding wires or brushwires. The invention also relates to a resilient card clothing, a stationary carding flat or a wire brush comprising elongated steel wires with a metallic coating for corrosion resistance. Background technique [0002] In general, so-called carding wires are of two types: steel wires for so-called flexible tops or elastic tops, and steel wires to be processed into toothed wires for fixing carding flats. [0003] In the production of textiles, the carding process is to arrange the fibers into a uniform state, that is, uniform density and uniform thickness, and to remove impurities. This can be done by means of elastic card clothings or by means of fixed flats. [0004] The e...
