(3) clean: the greasy dirt on cleaning rod base surface, dry up bar base surface water mark；
(4) the most continuously extruded of scaling powder is filled by band: the allumen bar base after cleaning is sent in tangential continuous extruder, extruding wheel and groove envelope block, plug squeezing action under, in extrusion die, form pipe；Use filler device by the through hole in powdery scaling powder press-in extrusion die, enter back in allumen pipe, to prepare the seamless allumen pipe of band scaling powder；
(5) swage: the seamless allumen pipe of band fluxing agent is sent into online and swaging apparatus carries out three grades of swagings processing obtains solid wire electrode；In rotary swaging process, the first pass reduction is 16-25%, and the second pass reduction is 12-20%, and following process rate is between 5-12%.
(6) drawing: the allumen welding rod after processing of swaging is sent in draw-off gear and carries out drawing to obtain required welding wire；
Described tangential continuous extruding technology is prepared the extrusion temperature of seamless tube blank and is 210-270 DEG C, and extrusion speed is 1.5-5r/min.
Beneficial effects of the present invention:
(1) can be by online smelting technology to control the composition of allumen in the allumen welding wire preparation method of the present invention；
(2) in the allumen welding wire preparation method of the present invention, horizontal casting can provide online and has preferable surface smoothness, roundness and the tangential continuously extruded bar base compared with low production cost；
(3) in the allumen welding wire preparation method of the present invention, the continuous extruding technology of band filling scaling powder uses a kind of tangential continual extruding technology, have production continuously, energy consumption is low, structure property is uniform, production efficiency is high and easily realizes automatically controlling of overall process, and by the through hole of mold cores to fill scaling powder, Automated condtrol can be realized；
(4) technique of swaging in the allumen welding wire preparation method of the present invention so that the inside and outside footpath of pipe reduces by high speed rotating FMT, is made scaling powder be compacted, and improves the structure property of pipe, it is simple to follow-up drawing process；
(5) combination of tangential continual extruding technology and swaging techniques in the allumen welding wire preparation method of the present invention, can obtain that structure property is excellent, relatively fine rule base almost without limit for length, to improve the efficiency of drawing tube reducing；
In sum, the preparation method of a kind of allumen welding wire of the present invention, there is solder good mechanical properties, scaling powder loses less, production efficiency is high, lumber recovery high and automaticity high.
