Abstract
The present invention relates to a method for manufacturing stainless steel wires by utilizing the boundary material of stainless steel bands, which belongs to the technical field of cold processing of metal. The present invention is mainly characterized in that the boundary material of stainless steel bands whose thickness is from 0.5 to 6.0mm is used as raw material, and then, the raw material is longitudinally cut into a plurality of narrow steel bands whose width is from 0.5 to 18mm by a rotary cutter; the needed ratio of the thickness to the width of each narrow steel band is 1:1 to 1:3; the narrow steel bands are rolled into cold rolling coil elements whose diameter is from 0.5 to 10mm by a cold rolling mill with circular holes, and then, the cold rolling coil elements are used for carrying out cool wire drawing production. The method of the present invention has the advantages of simplified manufacturing processes, simple production technology, low production cost and improved rate of finished products.
Description
The invention belongs to metal cold working apparatus and technology field, be specially adapted to the stainless steel band rim charge and make stainless steel wire.
Stainless steel wire is the quite big metal material of a kind of consumption, accounts for 10% of stainless steel total amount, and is of many uses at decoration, wire netting, welding wire, piano wire, bolt, nut, spring, rope and surgical implant steel wire etc.Countries in 1984 issue the stainless steel wire standard of eight different purposes.Several special steel plants and research institute's produced in small quantities.Because of stainless steel manufacturing process complexity, equipment investment is big, will adopt AOD or VOD method as smelting, or use electroslag remelting process, billet continuous casting etc.At present, domestic stainless steel wire is with its steel ingot or steel billet, is rolled into φ 8mm Production for Steel Wire by the cross-arranging type rod-rolling mill.Because stainless steel hot machining deformation drag is big, the high-speed rod-rolling mill examination is rolled the stainless steel wire rod production technology and is not passed a test, and can not supply the big volume of φ 6.5mm and heavily coil unit, is restricting the production of silk material, still fails to form the large-scale production ability.Investigation statistics shows, in stainless steel band production and application process, about 5% the limit of cutting can occur and consume, and these rim charges melted down and made steel it the past, and the sapwood material is good in fact, can be processed into a material raw material and be used.
The object of the present invention is to provide a kind of method of utilizing the stainless steel band rim charge to make stainless steel wire, this method manufacturing process simplifies, and production technology is simple, and production cost is low, and lumber recovery improves.
Based on above-mentioned purpose, main technical schemes of the present invention is to utilize the cutting edge clout of stainless steel band factory or stainless steel welded pipe factory to make raw material, the dimensional thickness 0.5-6.0mm of described cutting edge clout, width is 10-50mm, becoming width through disk shearing machine slitting again is some narrow steel strips of 0.5-18.0mm, it is 1 that the proportionate relationship of described narrow steel strip thickness and width requires: 1-1: 3, the cross section that is described narrow steel strip is a square or rectangular, above-mentioned narrow steel strip is rolled into the cold rolling wire of φ 0.5-φ 10mm by the cold-rolling mill of band round pass, carry out hand-drawn wire production with cold rolling wire then, the narrow steel strip of square section also can directly carry out hand-drawn wire production without round as a ball.
The round pass that is carved with different-diameter more than four pairs or four pairs on the cold roll of the used cold-rolling mill of this method is round as a ball with the stainless steel arrowband that is suitable for different size.
With make stainless steel wire with the hot rolling steel wire in the prior art and compare, the present invention has following advantage:
1, manufacturing process simplifies
Do not need from steel-making, save smelting, ingot casting, hot rolling cogging and hot-rolled steel wire process, replace the throwing of hot rolling steel wire with cold rolling wire, low cost of manufacture, with short production cycle, instant effect.
2, processing technology is simple
As mentioned above, adopt cold working process units and technology, production process is easy to control and management, and product quality is convenient to check and supervision, is formed quality certification system easily.
3, equipment is simple
Equipment investment is few, and the cycle of founding the factory is short, is convenient to form the large-scale production ability.
4, production cost is low
The conventional need from φ 8mm stainless steel steel wire to φ 1mm stainless steel wire pulled out journey with 9, about 9000 yuan/ton of producing cost, and the present invention utilizes the different-diameter cold rolling wire to make the stainless steel wire of corresponding specification, only needs 2-3 to pull out journey, 2090 yuan/ton of producing costs, manufacturing cost has reduced by 3/4.
5, lumber recovery improves
The enforcement of the inventive method can improve the finished product rate of cold rolled stainless steel band factory and stainless steel welded pipe factory more than 3%, and economic benefit is considerable.
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is a process unit schematic diagram of the present invention.
Fig. 2 is a cold roll garden shape pass configuration schematic diagram.
Among Fig. 1,1 uncoiling, 2 is straight and even, 3 inlet guide and guard, 4 garden disk stripings are cut, 5 outlet guides, 6 coiling machines, 7 uncoilings, 8 preceding guide and guard, 9 duo mills, 10 coiling machines, 11 annealing furnaces, 12 descaling baths, 13 dry powder are lubricated, and 14 drawbenches, arrow are represented activity relation up and down.
Among Fig. 2,15 top rolls, 16 lower rolls, 17 round passes.
Embodiment
Adopt method of the present invention to produce three batches of products respectively, every after tested technical indicator all reaches the GB4242-84 standard, and is supplied to the user on probation, obtains customer acceptance, and three batches of process of producing product are as follows:
1,3.0 * (20-50) * Cmm → be divided into, 3.0 * 6 * Cmm several → be rolled into φ 3.8mm steel wire → annealing → pickling → cold-drawn and become 2.5 of φ.
2,3.0 * (30-50) * Cmm → be divided into, 3.0 * 3.0 * Cmm several → be rolled into φ 2.7mm steel wire → annealing → pickling → cold-drawn and become 1.5 of φ.
3,3.0 * (20-50) * Cmm → be divided into, 3.0 * 3.0 * Cmm several → become φ 3mm steel wire (being similar to) → annealing → pickling → cold-drawn to become φ 2.0mm silk → annealing → pickling → cold-drawn to become φ 1.0mm silk with the reverse cold-drawn.
In addition, utilize above-mentioned three batches of products also can carry out filament and microfilament production.
