Intermediate frequency induction heating copper wire annealing equipment

1, mwachidule:

Intermediate frequency induction heating copper wire (copper tube ) annealing equipment is suitable for on-line annealing of copper wire (brass alloy outer sheath). The penetration depth and hardness are according to the specific requirements of customers to achieve stress removal and softening of the brass alloy. The purpose of the outer sheath.

Equipment introduction The complete set of equipment is designed and manufactured according to the mechatronics structure. Among them, the intermediate frequency power supply is a set of 6- pulse thyristor KGPS200KW/8KHZ intermediate frequency power supply, the load is a set of GTR series induction heating furnace, and the equipment is equipped with a set of reactive power compensation capacitor bank. The device is designed with manual and automatic power adjustment knobs, among which automatic is the temperature closed-loop control mode. The external control console is controlled by PLC (Siemens) and touch screen. The touch screen can easily input heating parameters, such as copper wire specifications, heating speed, annealing temperature, etc. After the parameters are input, the closed loop control system of the intermediate frequency power supply temperature will automatically adjust the output power, thereby Meet production needs. When a certain link in the production fails, the intermediate frequency power supply can be insulated according to the set temperature to avoid overburning the copper wire. The equipment is placed according to user requirements, facing the equipment from left to right, the operating table is placed toward the main equipment, which is conducive to the operator to observe the production situation and facilitate the adjustment of parameters.

Safety protection The equipment has complete safety protection measures, such as water shortage protection, phase lack protection, over current protection, over voltage protection, under voltage protection, high water temperature protection, etc., and there is an audible and visual alarm device for faults. The equipment is configured according to 200KW , leaving enough power margin to ensure continuous and stable production of the equipment for 24 hours. All exposed conductors are installed in the electric control box with a lock, and there are eye-catching safety reminders, so no electrical safety accidents will occur. Each interlocking device can avoid damage to equipment or copper wires due to manual misoperation.

Zida dongosolo The wathunthu zida chimakwirira dera pafupifupi 2000 * 1500mm, ndi pakati kutalika kwa 1000mm. Mphamvu yamagetsi imaphatikizidwa ndi thupi la ng’anjo yotentha, ndipo ma bolts owonjezera amagwiritsidwa ntchito kukonza. Zida zimapangidwa ndi cholumikizira chakunja, chomwe chitha kukonzedwa mwakufuna molingana ndi momwe malo alili, omwe ndi abwino kugwira ntchito. Kuyika kwa zida ndi kosavuta komanso kofulumira. Ogwiritsa amangofunika kulumikiza polowera madzi ndi mapaipi otulutsira madzi ndi polowera madzi ndi mapaipi otulutsira zida (nozzle imodzi panjira iliyonse yamadzi ndi potulutsa), ndikulumikiza waya wagawo atatu kumapeto kwa zida.

zolemba zamakono

2 .1 magawo aukadaulo wazinthu

Zida zogwirira ntchito: kudzera pawaya wapansi (mkati mwake ndi kondakitala wamkuwa, ndipo kunja kwake kumakutidwa mwamphamvu ndi mkuwa wa aloyi)

Njira ya Annealing: Kutenthetsa kosalekeza kwapaintaneti

Zofunika: φ 6- φ 13mm, khoma makulidwe 1mm

2 .2 Kutentha zofunika kwambiri luso

kutentha koyamba: 20 ℃;

Annealing kutentha: controllable ndi chosinthika mkati osiyanasiyana 600 ℃; Kuyeza kwa kutentha kwazitsulo zazitsulo zamkuwa ndi ± 5 ℃, ndi kuwongolera kutentha kwa kutentha kwa kutentha ndi ± 20 ℃.

Kutentha kwakuya: 2mm;

Liwiro la mzere wa ndondomeko: mkati mwa 30m / min (liwiro lalikulu la mzere siloposa 30m / min);

Pakati kutalika kwa mzere wopanga: 1m;

2.3 Kusankhidwa kwaukadaulo kwa zida zonse

Zida zonse zikuphatikiza makina owongolera ma frequency apakati, makina oyezera kutentha kwa ma infrared fiber optical, kutentha kotsekeka-loop control system, reactive power compensation capacitor bank, induction heat annealing ng’anjo thupi, etc.

Njira yowongolera mphamvu yapakati:

2.3.1 Mphamvu yapakatikati yamagetsi ndi chipangizo chamtundu wa thyristor, voliyumu yolowera ndi 380V, 50Hz, ndi mphamvu yotulutsa ndi 200KW. Mphamvu zimatha kusinthidwa pamanja kapena zokha malinga ndi kutentha komwe kumayikidwa. Ma frequency otulutsa ndi 8KHz (kutsata pafupipafupi). Mtundu wa nduna umatsimikiziridwa malinga ndi zomwe wogwiritsa ntchito akufuna, kukula kwa autilaini ndi 2000 × 1500 × 1300mm, ndipo kutalika kwapakati ndi 1000mm.

2.3.2 Mtundu wa cartridge wophatikizira silicon rack

Gawo la rectifier ndi inverter la thyristor limatenga mawonekedwe aposachedwa a silicon ophatikizika okhala ndi patent application. Njira yoyika iyi imapangitsa kuti disassembly ndi msonkhano wa thyristor ukhale wosavuta komanso wasayansi. Mukalowa m’malo mwa thyristor, ingomasulani Bawuti yolimbitsa imatha m’malo mwa chinthu chilichonse cha thyristor pamsonkhano. Kuphatikiza apo, njira yoyikayi imachepetsa kwathunthu kuchuluka kwa gawo la SCR, lomwe silimangowonjezera malo ogwirira ntchito mu kabati yamagetsi, komanso kumachepetsa kwambiri kutayika kwa mzere.

2.3.3 Mphamvu yayikulu ya DC yosalala yamagetsi

Smoothing riyakitala n’kofunika kwambiri olimba magetsi, ali ndi ntchito ziwiri. Choyamba, pangani zotulukapo za rectifier kukhala zosalala komanso zokhazikika. Chachiwiri, pamene inverter thyristor ndi yochepa-yozungulira, chiwerengero cha kukula kwa nthawi yachidule chamakono ndi kukula kwazomwe zimakhala zochepa kwambiri. Ngati makonzedwe a parameter a fyuluta riyakitala ndi osamveka, mfundo yaikulu si yabwino kapena njira yopangira si yabwino, idzakhudza kwambiri kudalirika kwa ntchito yamagetsi apakati.

2.3.4 SCR yokhala ndi mphamvu zazikulu

Pofuna kuwonetsetsa kudalirika kwa magwiridwe antchito a zida, onse okonzanso ndi inverter thyristors amagwiritsa ntchito Xiangfan station-based KP yayikulu ndi silicon ya KK kuwonetsetsa kuti zidazo zikugwira ntchito mokhazikika.

2.3.5 Gwiritsani ntchito zingwe zolipirira zotsatizana ndi zofananira kuti muchepetse kutayika kwa zingwe zotumizira

Kuti muchepetse kutayika pa mzere wapakatikati wotumizira ma frequency, capacitor ya inverter imalumikizidwa mndandanda ndi mawonekedwe ofananirako voteji.

2.3.6 Main dera magawo ndi chigawo kusankha maziko

Magawo ovoteledwa agawo lalikulu lamagetsi apakatikati akuwonetsedwa patebulo ili:

The inductor is composed of a furnace shell, an induction coil, a stainless steel water collector and a furnace lining. The induction coil is combined with the parameters of the annealed copper alloy tube to optimize the design with special computer software and make it in combination with actual experience. It can ensure the best electromagnetic coupling efficiency under the same capacity. Induction coils with 99.99% of T2 rectangular copper wire made, the induction coil outer insulating electrostatic spray process the epoxy resin insulating layer of high strength, pressure-resistant insulating layer is greater than 5000V .

The inner layer of the induction coil is made of white corundum lining, and the outside of the lining and between the coils are fixed with refractory cement (American Union Mine), which can play a role in insulation and heat preservation. At the same time, the strength of the white corundum lining is further increased, effectively avoiding copper wire damage to the lining.

Madzi onse mkati ndi kunja kwa sensa amasonkhanitsidwa muzitsulo ziwiri zosapanga dzimbiri zosapanga dzimbiri, zomwe zimagwirizanitsidwa ndi madzi akuluakulu olowera madzi ndi mapaipi otuluka. Madzi osungira madzi osapanga dzimbiri ndi okongola komanso othandiza, omwe amatha kupeŵa mogwira mtima chikoka cha kutentha kwa coil induction chifukwa cha kuwonongeka kwa chitoliro cha madzi ndi kutsekeka kwa njira yamadzi.
