Embodiment 1

[0028] A production method for stainless steel wire rod, comprising the following steps:

[0029] Process 1: Raw material selection and pretreatment

[0030] Select the scrap cut from the stainless steel plate as the raw material, and the scrap meets the following conditions:

[0031] 1) The shape is bar;

[0032] 2) The width is 8mm.

[0033] The stainless steel plate is a 200 series stainless steel plate.

[0034] Process 2: Welding the long strip

[0035] The raw materials with similar thickness and width are welded in seconds by butt joint method, and formed into long strips by leveling and straightening.

[0036] Process three: hole extrusion

[0037] The hole extrusion includes three processes: pre-extrusion, extrusion and fine extrusion;

[0038] The pre-extrusion includes 6 passes of extrusion deformation: the first pass is to process the edges and corners of the raw materials; the second pass is to narrow the raw materials after processing the edges and corners;...

Abstract

The invention relates to the technical field of metal smelting, in particular to a production method of a stainless steel wire rod material. The production method comprises the following steps: raw material selection and pretreatment; welding into a long strip; hole pattern extrusion; flying shear treatment; and taking up the wire. The production method does not involve steel smelting and steel rolling procedures, and is low in energy consumption, small in pollutant discharge amount and environmentally friendly; the used raw material is stainless steel waste, the raw material cost is low, and good economic benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of metal smelting, in particular to a production method of stainless steel wire rod. Background technique [0002] Stainless steel wire rods are used to produce stainless steel wires of various specifications and models. The products are widely used in petroleum, electronics, construction, machinery, military, chemical, precision instruments and other industries, and have broad market prospects and market needs. The existing stainless steel wire rod production process includes smelting stainless steel molten steel, refining the molten steel, producing steel billets, hot rolling or cold rolling to produce steel plates, flattening the steel plates, longitudinally (horizontally) cutting, and coiling to obtain wire rods thread. [0003] Chinese patent application CN106591734A (published on April 26, 2017) discloses a method for producing a high-strength martensitic stainless steel wire rod, which includes a hot...
