The method comprises the following process steps of: physically removing mill scale of a welding wire to be drawn in a husking machine; and performing an electrolytic pickling process under the condition that the movement speed of the welding wire to be drawn is 0.3 to 0.5 meter/second, the surface current density of the welding wire to be drawn is 150 to 350A/dm<2> and the temperature of an electrolyte solution is controlled to 15-60 DEG C, wherein the electrolyte solution consists of sulfuric acid, hydrochloric acid, sodium sulfate and an additive, and the additive consists of sodium dodecyl benzene sulfonate and alkylphenol polyoxyethylene ether. By the method, the problems of long pickling time, low production efficiency, non-ideal mill scale removing effect, environmental pollution and the like existing in the surface treatment process before the wiredrawing of the welding wire are solved.
Description
Technical field
The present invention relates to the welding wire production technical field, the continuous surface treatment process of carrying out before especially a kind of welding wire wire drawing.
Background technology
The welding wire of rolling uses very generally in the production line of mechanical industry, and usage quantity is very big.And mostly the processing of welding wire at present is to wait to draw welding wire after a series of drawing and other treatment process, to process the welding wire of all size rolling with thicker special of diameter.In electric welding wire product line, before drawing procedure,, require to remove its surface scale, foreign material such as greasy dirt for the raw material welding wire to be drawn of processing welding wire; At present raw material is waited that slightly drawing the oxide debris removal of welding wire is the traditional technology that adopts chemical pickling; Promptly directly carry out pickling with acids solution such as hydrochloric acid; Reach the purpose of removing oxide debris through the chemical reaction in the pickling; And this pickling is just to get into after accomplishing separately to draw the preface of exchanging work directly on the whole piece electric welding wire product line, not carry out continuously, therefore exists long, problems such as production efficiency is low, the scale removal effect is undesirable, environmental pollution of pickling time.
Summary of the invention
Technical problem to be solved by this invention provides the surface treatment process method before a kind of welding wire wire drawing; It can solve in the electric welding wire product line waits to draw the welding wire surface processing to exist the pickling time long to raw material; Production efficiency is low, the scale removal effect undesirable with problem such as environmental pollution.
In order to address the above problem, technical scheme of the present invention is: the surface treatment process method before this welding wire wire drawing, and its process step is successively: ⑴ removes the oxide debris of waiting to draw welding wire; ⑵ washing before the pickling; ⑶ electrolytic pickling; ⑷ pickling after washing; ⑸ oven dry; What said removal waited to draw welding wire waits that drawing the step of welding wire oxide debris is to carry out oxide debris at a decorticator to peel off; This decorticator includes at least one group by three axis arranged transverselys; Relative position is horizontal folding that horizontal sheave that " article " font arranges constitutes around wheels; Vertically be provided with by three axis with at least one group, relative position is vertical folding that vertical sheave that " article " font arranges constitutes around wheels; It is said that to wait to draw welding wire be around wheels its surperficial oxide debris to be broken away from around wheels and vertical folding through walking around said horizontal folding in said decorticator; Said electrolytic pickling step is that welding wire to be drawn is placed the electrolyzer that fills electrolytic solution is anode with welding wire to be drawn; With the stereotype is that negative electrode carries out electrolytic pickling; Its processing condition are: wait that drawing the translational speed of welding wire is the 0.3-0.5 meter per second, wait that drawing the surface current density of welding wire is 150-350A/d ㎡; Electrolyte temperature is controlled at 15-60 ℃; Electrolytic solution is made up of sulfuric acid, hydrochloric acid, sodium sulfate and additive, and its weight ratio is: sulfuric acid 1%-3.8%, and hydrochloric acid 1-2%, sodium sulfate 4-5%, additive 0.002-0.005%, surplus is a water; Said additive is made up of X 2073, TX10, and its weight ratio is: X 2073 50-80%, TX10 5-20%.
The more concrete scheme of surface treatment process method before the above-mentioned welding wire wire drawing is: the processing condition of said electrolytic pickling step are to wait that drawing the translational speed of welding wire is 0.5 meter per second; Wait that drawing the surface current density of welding wire is 350A/d ㎡; The temperature of said electrolytic solution is controlled at 25-35 ℃, and the weight ratio of the component in the said electrolytic solution is sulfuric acid 1%, hydrochloric acid 2%, sodium sulfate 5%; Additive 0.005%; The weight ratio of the component of its additive is an X 2073 80%, TX10 5%, and surplus is a water.
Because adopt technique scheme, the present invention compares with existing processes has following beneficial effect:
1, waiting to draw welding wire in decorticator, to roll over earlier around the wheels folding among the present invention compares the removal of oxide debris chemical reaction with existing acid solution around most of oxide debris of sloughing the surface; Not only can prevent to cause the matrix generation excessive erosion of not being with oxide debris or having a little oxide debris for treating the kickback that draws welding wire to remove the peel fast; And what is more important can also obtain the fast technique effect of decortication, is specially adapted to add in the welding wire wire-drawing production line and uses;
2, because to wait to draw the oxide debris of welding wire to remove be to adopt the mechanical-physical method to accomplish, therefore, comparable chemical corrosion decortication has reduced the consumption of acid solution greatly, has also exempted the processing of waste water and the pollution that environment is brought thereof.
