Abstract
The invention discloses a preparation method of a low-strength low-hardness steel wire, which uses a hot rolling wire as a raw material and comprises the following steps: drawing the hot rolling wire, carrying out heat treatment, and performing secondary drawing to obtain a finished steel wire, wherein 10 passes are used in the secondary drawing process, the hot rolling wire is a 42A hot rolling wire, and the molding compression ratio from the hot rolling wire to the finished steel wire after the heat treatment is 83-86%. The preparation method of a low-strength low-hardness steel wire breaks through the traditional process: the 42A hot rolling wire is used as a raw material, a semi-finished product is obtained after drawing and heat treatment, and the finished steel wire is obtained after 10-pass drawing. Besides, the prepared finished steel wire has high ductility and good torsional bending performance and prolongs the service life.
Description
Technical field
The present invention relates to a kind of preparation method of steel wire, relate in particular to a kind of Hubbing method of 1320MPA steel wire.
Background technology
Select for use the 45# hot rolling wire as raw material in the prior art,, get the finished product steel wire through Overheating Treatment and 10 passes of drawing, finished product steel wire total draught has only 78-80%, and steel wire drawing under-ageing causes steel wire toughness bad easily, reverse, bending value is not enough, steel wire poker toughness instability.
Summary of the invention
The present invention is intended to overcome above the deficiencies in the prior art, provides a kind of under the prerequisite that guarantees Steel Wire Surface hardness, prepares the method for 1320MPA grade tensile strength steel wire, and steel wire toughness is improved, and the torsional bending performance is good, and prolong service life.
Technical solution problem of the present invention adopts following technical scheme:
A kind of preparation method of low-intensity soft steel wire, with the hot rolling wire is raw material, after the drawing, heat-treat, get the finished product steel wire through redraing again, the number of times of described redraing is 10 passages, is characterized in: described hot rolling wire is selected the 42A hot rolling wire for use, and the hot rolling wire after the heat treatment is 83-86% to the moulding compression ratio of finished product steel wire.
Further, described redraing equipment therefor is a water-tank lorry, and design has wire drawing die on the described water-tank lorry, it is characterized in that described wire drawing die is joined mould according to following formula: d
n 2/ d
(n+1) 2=0.98*D
(n+1)/ D
n, D
nThe diameter on expression water-tank lorry driving cone pulley n rank, d
nThe linear diameter that goes out of representing n wire drawing die of steel wire; The span of n is the integer between 1～9.
Described passage is meant from semi-finished product moves the used wire drawing die quantity of finished product steel wire to.
Beneficial effect of the present invention is as follows:
The preparation method of steel wire thereof of low-intensity soft of the present invention is broken through tradition, and to select model for use be that the hot rolling wire of 42A is a raw material, through getting semi-finished product after drawing, the heat treatment, again through getting the finished product steel wire after 10 passes of drawing, the finished product steel wire that makes, case hardness 360 ± 20HV, the toughness height, the torsional bending performance is good, and prolong service life.
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the present invention is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, and be not used in qualification the present invention.
