Abstract
An improved lubricating technology for drawing the steel-in-aluminium wire features that the drawing powder is used as the lubricant for the first several drawing passes and the lubricating oil is used as the lubricant for the last several drawing passes in order to increase the drawing speed and the quality of product.
Description
Technical field
The invention relates to improvement, relate in particular to the wire-drawing lubrication cooling aluminium Baogang drawing process.
Background technology
Existing domestic and international aluminum-clad steel wire drawing process: a class promptly all adopts the wire drawing powder to make lubricant in the wire drawing overall process for adopting the dry wire drawing method; Another kind of for adopting the wet type fiber elongation method, promptly in the wire drawing overall process, all adopt oil to make lubricant.The wire drawing powder is made the dry wire drawing of lubricant, as Chinese patent 92102030.9 disclosed aluminium clad steel wire drawings, adopt the pressed powder lubricant, because wire drawing powder viscosity is bigger, along with continuous wire drawing, silk draws thinner and thinner, speed is also drawn higher and higher, temperature in the mould also raises fast with the raising of its speed, and a part of lubricating grease in the wire drawing powder easily is sintered like this, and it is surperficial and taken out of firmly to be adsorbed on aluminum-clad steel wire, thereby cause aluminium Baogang monofilament surface to be black or grey, do not had brightness, fineness is poor, thereby surface quality is poor.Secondly, make lubricant with the wire drawing powder, in aluminium Baogang cladding process, can't obtain revising to established cladding blank off-centre, the product external diameter easily produces fluctuation, therefore its f value is generally between 0.07-0.1mm, concentricity, performance indications are in the minimum degree of eccentricity edge of national Specification, are difficult to reach high-quality product.All adopt the oil lubrication wire drawing, as described in Chinese patent 03131560.7, utilize lubricating oil to draw aluminum cald steel wire as lubricant medium, however poor because of the lubricating oil cooling effect, add that clad material intensity is low, therefore drawing speed is relatively low, Reduction per draft is little, per pass≤15%, thereby the wire drawing passage need increase 4-6 passage than powder lubrication wiredrawing, production efficiency is lower, and lubricating oil leak pollute heavy, big to the influence of environment, and required auxiliary equipment is more.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned prior art, a kind of surface quality that significantly improves aluminium Baogang finished product monofilament is provided, improve concentricity, can keep higher drawing speed again, and the aluminium Baogang wire-drawing lubrication technology of high production efficiency.
The object of the invention realizes, the main improvement is to adopt powder to lubricate+the composite lubricated drawing process of oil lubrication (oil behind the preceding powder) in aluminium Baogang drawing process, so both kept the advantage of powder lubrication wiredrawing, brought into play the advantage of oily wire drawing simultaneously again, both pluses and minuses complementations reach best of breed.Specifically, aluminium of the present invention Baogang wire-drawing lubrication technology, some roads adopt the wire drawing powder to make lubricant before it is characterized in that, and last or a few road adopt oil lubrication.
The present invention fully coordinates two kinds of wire-drawing lubrications, make it to reach best of breed, through a large amount of tests, use oil lubrication to be best of breed when wherein drawing with last one finishing die especially, can bring into play the lubricated advantage of powder so to greatest extent, simultaneously also can satisfy the object of the invention, reach and improve surface quality, improve concentricity.
For making wire drawing aluminium Baogang that better appearance property be arranged, the present invention is a kind of better to be to be added with polishing agent in lubricating oil again, can make like this monofilament surface that draws out brighter, can reach surface-brightening and fineness behind the stainless steel wire drawing.
The present invention reduces environmental pollution for improving the lubricating oil utilization rate, lubricating oil recirculation after absorbing, filtering can be used.
Aluminum cald steel wire of the present invention draws, because preceding some roads adopt the wire drawing powder lubricated, last several roads (especially together last) adopts oil lubrication, both improved the surface quality of aluminium Baogang finished product monofilament, keep higher drawing speed again, can reach the identical speed of powder wire drawing, the production efficiency height; Oil lubrication, can utilize the pressure mould with the splash ring of trace around aluminium Baogang monofilament surface, produce high pressure by the pressure mould, the aluminium Baogang monofilament of off-centre can be set upright, make its isostasy, concentricity is improved, the f value can be controlled between the 0.02-0.04mm, and the outward appearance no marking does not have greasy dirt yet.Preceding some roads powder is lubricated, and good percentage elongation is difficult for crisp silk, and the silk intensity stabilization does not increase wire drawing road number, and last lubricating oil is very even at the oil film of pressure constant state formation, has effectively overcome powdered lubricant and has easily caused quality fluctuation, and wire drawing yield rate height reduces production costs.Add polishing agent in the lubricating oil again, improved surface quality especially, can reach surface-brightening and fineness behind the stainless steel wire drawing.Lubricating oil absorbs, filters back recirculation to be used, and has not only reduced cost consumption, and can not cause environmental pollution.The present invention has started aluminium Baogang wire-drawing lubrication new technology.
Below in conjunction with a specific embodiment, further specify the present invention, but the embodiment specific embodiment is not a limitation of the invention.
The specific embodiment
Embodiment: with the continuous wire drawing of eight moulds is example, and the wire drawing total draught is controlled in 80%, and the slubbing compression ratio is controlled at about 20-22%, and two road compression ratios are controlled at about 20-22%, and later passage reduces gradually, and last one compression ratio is controlled at 8-12%.Wherein the first seven road wire drawing adopts the wire drawing powder lubricated, and last one finishing die adopts lubricating oil to add polishing agent.Wherein lubricating oil adopts the filtration cycle form to add, to reach repeated use.
For convenience of description, said oil lubrication of the present invention and lubricating oil are synonym.
Claims (5)
1, a kind of aluminium Baogang wire-drawing lubrication technology, some roads adopt the wire drawing powder to make lubricant before it is characterized in that, and last or a few road adopt oil lubrication.
2, according to the described aluminium of claim 1 Baogang drawing process, it is characterized in that said oil lubrication one finishing die in the end.
