Abstract

The invention relates to a textile fuzzing flexible card clothing steel wire rod and belongs to the technical field of the special steel wire rods. The wire rod meets the conditions that the tensile strength is 1000-1200 Mpa, and the reduction of area is greater than 45%; a microstructure of the steel wire rod meeting the tensile property comprises 85% or more of the sorbite content and the balance ferrite; the sorbite interlamellar spacing is uniformly controlled, wherein the interlamellar spacing is stable at 0.08-0.20 [mu]m; nonmetallic inclusions in the wire rod are evaluated according toGB / T10561; Ds type inclusions are stable at 0.5 level or less, and the deep drawing of the wire rod can be met; and the wire rod with the diameter of 5.5 mm can be drawn into a thin steel wire with the diameter of 0.2 mm, and then quenched and tempered into a flexible card clothing.

Description

technical field

[0001] The invention relates to an iron-based special wire rod, in particular to a steel wire rod for wet-raised elastic card clothing in the textile field and a production method thereof. Background technique

[0002] In recent years, the demand for textile fleece products has been increasing, resulting in a shortage of fleece elastic card clothing. High-grade fleece elastic wire steel wires are mainly imported from Japan and Germany. Imported card clothing cannot be established for a long time due to factors such as long delivery cycle and high cost. The domestic urgent need Develop high-grade raised elastic card clothing wire rod.

[0003] Raised elastic card clothing steel wire processing technology: 5.5mm wire rod—drawing—heat treatment—drawing until the final product diameter is as thin as about 0.2mm—steel wire quenching and tempering—finished product. In order to avoid brittle fracture of the material during needle bending and use, higher requirement...
