Abstract
The invention relates to a high-performance knitted steel wire and a production process thereof. The steel wire uses high-carbon steel containing vanadium and chromium as raw materials. The specific production process comprises: heating the raw material to obtain the pre-treated steel wire, wherein the heating processing comprises spheroidizing, drawing, crystallizing, drawing and softening; performing pickling for the pre-treated steel wire, coating with boron, putting the coated steel wire on a pay-off stand for drawing, winding the wire to obtain semi-finished steel wire, performing bright annealing for the semi-finished steel wire, and cooling to obtain the finished knitted steel wire. The steel wire provided by the invention is good in toughness, strong in wear resistance, good in elasticity performance, few in production processes and low in energy consumption.

Technical scheme: the knitting steel wire of high-performance of the present invention, it adopts and contains the high-carbon steel of v element and chromium element as the stock wire rod, its production technique be wire raw material wire rods through thermal treatment, be coated with boron processing, drawing, clean annealing to the finished product steel wire, its concrete technology step is:
A. wire raw material wire rods is carried out spheroidizing, be cooled to normal temperature after processing, cooled wire rod is placed in carries out drawing, take-up on pay off rack;
B. the wire rod after step a drawing is carried out crystallization treatment, be cooled to normal temperature after processing, cooled wire rod is placed in carries out drawing, take-up on pay off rack;
C. the wire rod after step b drawing is softened processing, be cooled to normal temperature after processing and get the pre-treatment steel wire;
D. zone of oxidation is removed in the pickling of pre-treatment steel wire, the follow-up boron that is coated with is processed, and processes post-drying, and oven dry is placed on carries out drawing on pay off rack, and take-up gets process wire;
E. process wire is carried out clean annealing, cooling is the finished product steel wire afterwards.
The described boron that is coated with is treated to steel wire is immersed borax, the tri-sodium phosphate that mass ratio is 2.5:1, and volume is in the water mixed liquid of 1.5 cubic metres, liquid temperature 80-90 ℃, to flood and took out drying treatment in 3-5 minutes.
As optimization, described spheroidizing process for wire rod is heated to 740～750 ℃ and be incubated 4～5 hours after furnace cooling to 450～620 air cooling of ℃ coming out of the stove again.
As optimization, described crystallization treatment process for wire rod is heated to 670～680 ℃ and be incubated 3.5～4.5 hours after furnace cooling to 450～600 air cooling of ℃ coming out of the stove again.
As optimization, described softening treating processes for wire rod is heated to 660～670 ℃ and be incubated at 3～4 o'clock after furnace cooling to 450～600 air cooling of ℃ coming out of the stove again.
Beneficial effect: good toughness of the present invention, fastness to rubbing is strong, elastic performance good and production process is few, and energy consumption is low.
