Abstract
A process method for removing oxide skin on the surface of a metal wire is characterized in that a mechanical physical method is adopted to remove the oxide skin on the surface of the metal wire, namely the metal wire is utilized to generate friction with sand grains in power, and the oxide skin on the surface of the metal wire and wiredrawing oil are removed together through the sand grains. The process method has the advantages that the problem of pollution caused by acid cleaning and alkaline cleaning in the welding wire production process is successfully solved through the mechanical physical technology for removing the oxide skin, the alkaline cleaning and acid cleaning process can be saved when the technology is used for copper plating welding wire, the cost of chemical engineering materials such as alkaline and acid is reduced by over 50 yuan per ton, 2/3 of cleaning water is also saved, the technology can also be used for directly producing a white wire (a welding wire free of copper plating), equipment investment is little, and the cost for producing the welding wire is reduced to the lowest.
Description
Technical field
The present invention relates to a kind of processing method of metal material, be specifically related to a kind of method of removing wire surface oxide skin.Be mainly used in surface treatment wiry.
Background technology
General carbon steel metalloid steel can produce layer of oxide layer at the exocuticle of metal after long-term storage, be commonly called as corrosion; In the process of machining, also often by oil pollution, gas cutting mouth edge also can residual a large amount of oxide skin.Welding wire also can get rusty owing to the humidity that deposits the place in or be surperficial unclean.The moisture that contains volume in these greasy dirts and the iron rust, they are to cause weld seam to produce the principal element of pore.And submerged-arc welding is very responsive to iron rust, and weld seam often occurs by the caused pore of iron rust.Therefore, must carry out processing of rust removing to weldment and welding wire surface before the weldering, just scale removal is handled.Now general said wire rod is carried out the pre-treatment line; Be exactly that the oxide skin that it is surperficial is removed clean; And at its surfaces coated last layer borax; Can reduce lousiness, fracture of wire phenomenon in the wire drawing process like this, prolong the service life of wire-drawing die, make the drawing of back can high speed, carry out smoothly.Handle the technology that various wires are still specially united at present; The technology of oxide skin is on traditional removal metal welding wire epidermis:
Wire drawing → electrolytic alkaline cleaning → washing → pickling → washing → passivation → change plating → washing → polishing → layer around → packing;
Because after wire drawing machine drawing repeatedly, make the remaining a large amount of dirts of wire surface: stay a lot of remnants as handling oxide-film that the back generates, phosphating coat etc. through heat treatment, phosphatization or corroding you through strong acid; The pickling overlong time makes wire can stay graphitic carbon and makes wire produce crisp or fracture of wire phenomenon; Attachment after lubricant (hot candied powder) process high temperature, the extruding etc.These dirts are under the situation of high speed travelling wire, and the strong acid treatment of short time is to be difficult to thoroughly remove.Present unique production technology; Be by concentrated acid pond immersion → high pressure water washing → on put guide frame → anode electrolytic tank or the cleaning → plating of alkaline bath cleaning → rinsing bowl.The technology of this special system is extended down to so far from eighties of last century the fifties, is heavily contaminated environment source, owing to adopt strong acid pickling; And strong acid is separated out a large amount of hydrogen; The hydrogen of separating out can pollute 1000 square metres environment, diminishes bad person's body body official, very influences health Jiankang.Owing to adopt by concentrated acid pond immersion → high pressure water washing and anode electrolytic tank or alkaline bath cleaning → rinsing bowl and clean dual cleaning; Very waste water resource is produced about 5000 kilograms of one ton of silk water consumptions, produces a large amount of sewage; Be the heavily contaminated source, also need build treatment tank.This technology and contaminated environment be the polluted underground water resource again, very consumes wealth again.Be that country orders the heavily contaminated source enterprise that forbids.
But there are some problems that can't avoid in the technology of descale on the existing metal welding wire epidermis:
1, sewage disposal difficulty is big.Traditional handicraft: add thermokalite oil removing → washing → pickling and remove oxide → washing → passivation.The sewage of producing is divided into two, and one is the rinse water after the oil removing, the rinse water after the pickling when producing at ordinary times; Another piece is the replacing waste liquid of oil removing, Acidwash solution.Contain a large amount of iron ions in the sewage.
2, sewage disposal: must precipitate with limewash.
3, the bad welding wire that produces after the copper facing, it is cumbersome to do over again again, so the welding wire that traditional handicraft is produced is useless more, and can only work as scrap iron and sell.
Therefore necessary technology to descale on the existing metal welding wire epidermis is improved.
Through the domestic Searches of Patent Literature, do not have to find document that some patents about metal descale aspect are just arranged relevant for welding wire descale aspect, mainly contain the following:
1, one Chinese patent application number is CN200910048408.5, and name is called " 0.03mm special titanium microfilament processing technology ", and this patent discloses a kind of 0.03mm special titanium microfilament processing technology; Belong to metal fining-off field; Its main flow process is handled three parts by wire drawing, heat treatment, oxide skin and is formed, and mould bases and wire drawing axle two fixed method are all adopted in twice wire drawing, adopt special lubricant; Reduced the frictional force at titanium silk surface and wire drawing die calibrating strap position; Twice heat treatment process adopts different heat treatment temperature or annealing point, and the linear velocity that remains a constant speed, and solves the low and bad problem of percentage elongation of tensile strength of titanium silk; The oxide skin processing procedure adopts the method for single line bull continuous wash, reduces the titanium silk at the resistance in putting each link such as guide frame, rinse bath, rinsing bath, oven dry, take-up.
2, the patent No. is CN200720155600.0, and name is called the Chinese patent of " wire surface processor ", and this patent discloses a kind of wire surface processor; Be characterized on two winding rollers, repeatedly being wound with back and forth wire rod; The upper and lower intersection of deck wire is evenly equipped with the steel wire polishing wheel above that, and following polishing wheel leans on axle, bearing fixing on following polishing wheel support, and the support two ends are provided with slide rail and bolt and nut governor motion; Last polishing wheel leans on axle, bearing fixing on last polishing wheel support; The one of which end is connected on the slide block by axle, and slide block is connected with the frame axle, and slide block is provided with the bolt and nut governor motion; Its other end is provided with chute staking and bolt and nut position-limit mechanism, and polishing wheel leans on sprocket wheel or belt pulley, chain or belt to divide a upper and lower word to connect by motor through the speed change power transmission shaft.
Above-mentioned these patents obviously and welding wire be that it doesn't matter; Therefore how to improve the existing practical problem of welding wire descale; Be a major issue that improves the welding rod product quality, the necessity that still need further study the technology of descale on the metal welding wire epidermis.
Summary of the invention
