Description
Technical field
The utility model relates to a kind of flux-cored wire production system, especially relates to the Drawing-anneal system in a kind of flux-cored wire production process.
Background technology
Flux-cored wire is a kind of Novel welding material developed rapidly in recent years, obtains widespread use in developed country.Flux-cored wire has obvious advantage compared with manual electrode, mainly interrupted welding process is become continuous print welding process.Thus decrease the number of welding joint, improve welding quality.Also improve production efficiency, save the energy.
Flux-cored wire is also referred to as tubular wire, can by the kind of Correctional tube Chinese medicine core additive and ratio, design the welding material of various different purposes easily, because its alloying constituent can be flexible adjustment, cannot smelt and roll so many kinds of flux-cored wire are solid welding wires.
Flux-cored wire is divided into again seamed and seamless two kinds, and are all the tubular wires be rolled into by strip metal, medicine core is all wrapped in pipe.Difference is: seamed cored wire closes seam by mechanical hook volume mode, is enclosed in pipe crimping by medicine core; Seamless flux-cored wire closes seam by welding process, is sealed in completely in pipe crimping by medicine core.
No matter be seamed or seamless flux-cored wire, package medicine core is all that Ф 10 about ㎜ carries out when the diameter of tubular wire is thicker.No matter machinery closes and is sewed with or welds that to close seam seamless, and flux-cored wire all will through repeatedly: mechanical pull---annealing---drawing---annealing---drawing.Flux-cored wire could be elongated, drawing-down, reach diameter Ф 1.5-Ф 3 about ㎜ of needs.
The technological problems run into is, when during annealing, flux-cored wire is heated to annealing temperature and is incubated in electrical heater, metal welding wire undergoes no deterioration, but the medicine core in pipe cannot stand long high temperature, can go bad, medicine core performance declines, and can affect flux-cored wire welding quality thereafter.And stress relief annealing is the technical process therefore existing heating system urgent need improvement that mechanical pull welding wire is not walked around together.
Utility model content
The purpose of this utility model easily makes the inner medicine core of flux-cored wire go bad in traditional heating mode to affect the problem of performance, provide the Drawing-anneal system in a kind of flux-cored wire production process for solving existing flux-cored wire.
The utility model is the deficiency solved the problems of the technologies described above, and the technical scheme adopted is:
Drawing-anneal system in a kind of flux-cored wire production process, comprise direct supply, voltmeter, reometer, slide rheostat and temperature sensor, the tubular wire of flux-cored wire to be processed and slide rheostat are connected to the two ends of direct supply after connecting, so that changed by the electric current of flux-cored wire to be processed by the resistance of adjustment slide rheostat with control temperature, voltmeter and reometer are connected on tubular wire so that survey the voltage and current on tubular wire, the arranged outside of described tubular wire has temperature sensor, so that the temperature on detection tubular wire.
Described temperature sensor is provided with a plurality of two ends and the middle part that lay respectively at tubular wire.
The beneficial effects of the utility model are: the utility model changes traditional heating mode, adopt electrically heated, tubular wire two ends are added electric current, at flux-cored wire two ends and central set temperature sensor, according to the temperature value that sensor shows, adjustment varistor, changes the size of electric current, thus controls the temperature of heating.According to annealing process, make flux-cored wire surface temperature reach heat treated temperature, keep certain hour.Reach to the object of tubular wire annealing.Simultaneously due to the skin effect of electric current, the welding wire in pipe can not be added thermal metamorphism, doing so avoids medicine core performance and declines, ensure that flux-cored wire welding quality in use.
Accompanying drawing explanation
Fig. 1 is principle schematic of the present utility model.
Graphical indicia: 1, flux-cored wire to be processed; 2, temperature sensor.
Embodiment
Shown in figure, embodiment is as follows:
Drawing-anneal system in a kind of flux-cored wire production process, comprise direct supply, voltmeter, reometer, slide rheostat and temperature sensor 2, the tubular wire of flux-cored wire 1 to be processed and slide rheostat are connected to the two ends of direct supply after connecting, so that changed by the electric current of flux-cored wire 1 to be processed by the resistance of adjustment slide rheostat with control temperature, voltmeter and reometer are connected on tubular wire so that survey the voltage and current on tubular wire, the arranged outside of described tubular wire has temperature sensor 2, so that the temperature on detection tubular wire.
Described temperature sensor 2 is provided with a plurality of two ends and the middle part that lay respectively at tubular wire.
In order to solve the problem that the heating of existing type of heating easily makes medicine core rotten, and reach and can anneal to welding wire, do not make again the object that medicine core is rotten, heat treatment mode in the past must be changed, only heat welding wire and do not heat core wire.
According to joule lenzs law: Q=0.24I2Rt(Q---heat card, I---amps, R---resistance value ohm, t---second conduction time) and the skin effect (electric current is only in conductive line surfaces flowing) of conductor conduction, thus propose the heating system in the utility model.
Tubular wire two ends are added electric current, and at flux-cored wire two ends and central set temperature sensor, according to the temperature value that sensor shows, adjustment varistor, changes the size of electric current.According to annealing process, make flux-cored wire surface temperature reach heat treated temperature, keep certain hour.Reach to the object of tubular wire annealing.Simultaneously due to the skin effect of electric current, the welding wire in pipe can not be added thermal metamorphism.
The principle of this heat-treatment of annealing technology utilization joule lenzs law: Q=0.24I2Rt and electric current skin effect, has made the electric heater unit of tubular wire, has solved heating by electric cooker flux-cored wire dexterously, can cause the problem that medicine core is rotten.
Technical scheme cited by the utility model and embodiment be not restriction, be equal to the technical scheme cited by the utility model and embodiment or effect same approach all in the scope that the utility model is protected.
