Description

Technical Field

[0001] This utility model relates to the field of heating tube technology, and in particular to an ultrasonic induction heating tube. Background Technology

[0002] Ultrasonic heating tubes are a type of equipment component that heats metal workpieces based on the principle of electromagnetic induction.

[0003] However, traditional ultrasonic heating tubes generally adopt a single coil and no inner tube structure. When heating steel wire with traditional ultrasonic heating tubes, the temperature rise of the steel wire can generally only control the final temperature of the steel wire, and cannot control the temperature of the steel wire at various locations. This results in uneven grain growth inside the steel wire, which easily leads to wire breakage during subsequent processing. At the same time, the steel wire is exposed to the air during heating, which will produce a large amount of oxide scale, reducing the output of steel wire. Utility Model Content

[0004] The purpose of this invention is to provide an ultrasonic induction heating tube that solves the problem that existing ultrasonic heating tubes generally adopt a single coil and no inner tube structure. When heating steel wire with traditional ultrasonic heating tubes, the temperature rise of the steel wire can generally only control the final temperature of the steel wire, and cannot control the temperature of the steel wire at various locations. This results in uneven grain growth inside the steel wire, which easily leads to wire breakage during subsequent processing. At the same time, the steel wire is exposed to the air during heating, which produces a large amount of oxide scale, reducing the production of steel wire.

[0005] To achieve the above objectives, this utility model provides an ultrasonic induction heating tube, which includes a housing, a quartz tube, a protective gas input tube, two heating coil units, and two sealing plates. The quartz tube is disposed inside the housing, and the sealing plates are disposed at both ends of the housing. Each sealing plate has a feed port at its center, which corresponds to the quartz tube. The protective gas input tube is disposed through the middle of the quartz tube, and a protective gas input port is disposed at one end of the protective gas input tube extending to the outside of the housing. The heating coil units are disposed on both sides of the protective gas input tube, and the two heating coil units are disposed between the inside of the housing and the outside of the quartz tube.

[0006] Each heating coil unit is composed of multiple induction coils. Each induction coil is disposed outside the quartz tube, and both ends of each induction coil extend to the outside of the housing. One end of the induction coil is provided with a cooling water interface, and the other end of the induction coil is provided with a power connector.

[0007] Each of the sealing plates has a thread-passing die at its material inlet.

[0008] The interior of the shell is filled with thermal insulation material.

[0009] This utility model discloses an ultrasonic induction heating tube, comprising a shell, a quartz tube, a protective gas input pipe, two heating coil units, and two sealing plates. By setting two heating coil units and controlling them independently, the temperature of the steel wire at each stage can better match the standard heating curve, which is conducive to the growth and formation of internal grains in the steel wire, resulting in more uniform internal grains, better wire flow, and benefits from subsequent processing of the steel wire. Furthermore, through the protective gas input port and the protective gas input pipe, protective gas is introduced into the interior of the quartz tube, allowing the steel wire to be heated in an oxygen-free environment, reducing oxidation loss of the steel wire. At the same time, the reduction of oxides helps to keep the inside of the quartz tube clean, reducing the frequency and number of cleanings required for the quartz tube. Attached Figure Description

[0013] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0014] Please see Figure 1This utility model provides an ultrasonic induction heating tube, which includes a housing 101, a quartz tube 102, a protective gas input pipe 103, two heating coil units, and two sealing plates 104. The quartz tube 102 is disposed inside the housing 101, and the sealing plates 104 are disposed at both ends of the housing 101. Each sealing plate 104 has a feed port 105 at its center, which corresponds to the quartz tube 102. The protective gas input pipe 103 is disposed through the middle of the quartz tube 102. The protective gas input pipe 103 extends to the outside of the housing 101 and has a protective gas input port 106 at one end. The heating coil units are disposed on both sides of the protective gas input pipe 103, and the two heating coil units are disposed between the inside of the housing 101 and the outside of the quartz tube 102.

[0015] In this embodiment, by setting two heating coil units and controlling them independently, the temperature of the steel wire at each stage can better match the standard heating curve, which is conducive to the growth and formation of internal grains in the steel wire. The internal grains are more uniform, the wire has better flowability, and it is beneficial to the subsequent reprocessing of the steel wire. Furthermore, by cooperating with the protective gas inlet 106 and the protective gas inlet pipe 103, protective gas is introduced into the interior of the quartz tube 102, so that the steel wire is heated in an oxygen-free environment, reducing the oxidation loss of the steel wire. At the same time, the reduction of oxides helps to keep the inside of the quartz tube 102 clean, reducing the frequency and number of cleanings required for the quartz tube 102.

[0016] Furthermore, each of the heating coil units is composed of multiple induction coils 107. Each induction coil 107 is disposed outside the quartz tube 102. Both ends of each induction coil 107 extend to the outside of the housing 101. One end of the induction coil 107 is provided with a cooling water interface 108, and the other end of the induction coil 107 is provided with a power connector 109.

[0017] In this embodiment, since each heating coil unit is composed of multiple induction coils 107, the temperature of the steel wire at each stage can better match the standard heating curve, which is conducive to the growth and formation of internal grains in the steel wire, making the internal grains more uniform and improving the wire's flowability. The cooling water interface 108 is used to cool the induction coil 107, and the power connector 109 is used to supply power to the induction coil 107.

[0018] Furthermore, each of the sealing plates 104 is provided with a wire guide die 110 at the material outlet 105.

[0019] In this embodiment, the wire guide 110 is used to guide the feeding of the steel wire.

[0020] Furthermore, the interior of the housing 101 is filled with thermal insulation material.

[0021] In this embodiment, by filling the interior of the housing 101 with heat-insulating material, heat loss is reduced, and the heating effect is better when heating the steel wire inside the quartz tube 102.

[0022] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
