Take-up step after step, unwrapping wire step implement coating step after coiled steel wire inner core 11 is unfolded, is tensioned；Take-up step
It is wound after the steel wire for coating and curing is tensioned.
Wherein, the production equipment degree steel wire inner core 11 that coating procedure is provided by embodiment two is implemented, and steel wire inner core 11 passes through
The mold base 41 of applicator assembly is implemented after realizing coating operation using the ultraviolet radiation-curable formation of ultraviolet light generating apparatus
The steel wire that example one provides.
Steel wire inner core 11 to be coated is wound payoff reel 21,11 unwrapping wire of steel wire inner core of payoff reel 21 by coating,
Become steel wire winding after curing and form take-up volume 31.Unwrapping wire tensioning apparatus 22 is provided between 21 applicator assembly of payoff reel,
Take-up tensioning apparatus 32 is provided between take-up volume 31 and ultraviolet light generating apparatus 10.
Batch mixing step at least one embodiment of the present invention includes mixing, preheating and defoaming, and wherein preheating temperature is 40
℃。
It should be noted that in batch mixing step, there is a mixer in mixing tank for coating colors 9, ceaselessly move, be on the one hand batch mixing,
On the other hand the bubble in material is blended and discharged.Meanwhile batch mixing step plays an important role of defoaming.
The production technology of steel wire is mainly coated and cured in the embodiment of the present invention, and rust-proof coating 12 is by applicator assembly
Made of coating, solidification temperature can adjust according to speed of production, therefore the factor that speed of production is restricted is smaller, substantially
On can reach solidification temperature can be promoted how much, speed of production can be promoted how much.And existing steel wire phosphorization process needs
Steel wire keeps the regular hour to ensure the thickness of phosphate coating in phosphating pond.Therefore, the production of steel wire provided in this embodiment
Speed is higher than phosphating steel wire
As can be seen that the method for production steel wire provided in an embodiment of the present invention, does not generate in production process any harmful
The substance that pollutes the environment such as gas, powder, residue or liquid, and in process of production except ultraviolet light cure expend compared with
Few electric energy is outer (DC frequency-changing control UV lamp may be employed, direct current can more effectively control the brightness of lamp), other are all
The air pressure of process use, the energy consumption of mechanical tensioning are very low.On the whole, the method for this production steel wire is in each process of above-mentioned steel wire
The energy consumption of middle generation belongs to energy saving and environment friendly infant industry production far below the energy consumption that production phosphating steel wire generates.
It should be noted that above-mentioned whole production process should be waterproof and dampproof, applied because the invasion of moisture will cure ultraviolet light
The substances such as the photoinitiator in material generate hydrolysis, so as to reduce solidification effect of the rust-proof coating 12 on steel wire inner core 11.Also,
Line speed can be promoted to 200-350m/min, but solidification temperature should be promoted with the promotion of speed of production.
Finally it should be noted that：The above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe is described in detail the present invention with reference to foregoing embodiments, it will be understood by those of ordinary skill in the art that：Its according to
Can so modify to the technical solution recorded in foregoing embodiments either to which part or all technical characteristic into
Row equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is not made to depart from various embodiments of the present invention technology
The scope of scheme.
