Intermediate frequency induction heating copper wire annealing equipment

1 , Isishwankathelo:

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.

Ubume bezixhobo Iseti epheleleyo yezixhobo igubungela indawo emalunga ne-2000 * 1500mm, kunye nobude beziko obuyi-1000mm. Ukunikezelwa kwamandla kuhlanganiswe nomzimba wesithando sokufudumala, kwaye iibholiti zokwandisa zisetyenziselwa ukulungisa. Izixhobo zenzelwe i-console yangaphandle, enokuthi ihlelwe ngokuthanda ngokwemiqathango yesayithi, ekulungele ukusebenza. Ukufakwa kwezixhobo kulula kwaye ngokukhawuleza. Abasebenzisi badinga kuphela ukudibanisa i-inlet yamanzi kunye nemibhobho yokuphuma kunye ne-inlet yamanzi kunye nemibhobho yokuphuma yesixhobo (i-nozzle enye kwindawo yokungena kwamanzi kunye nokuphuma), kwaye udibanise izigaba ezithathu zocingo ukuya ekupheleni kwesixhobo.

Ubushushu be-Anealing: bulawuleka kwaye bulungelelaniswe phakathi koluhlu lwe-600 ℃; ukuchaneka kovavanyo lobushushu bomaleko wengxubevange yobhedu yi ± 5 ℃, kunye nokuchaneka kokulawula ubushushu bokufudumala kwe-induction yi-± 20 ℃.

Ubunzulu bokufudumala: 2mm;

Isantya somgca wenkqubo: ngaphakathi kwe-30m / min (isantya esiphezulu somgca asiphezulu kune-30m / min);

Ubude beziko lomgca wemveliso: 1m;

2.3 Ukukhethwa kweteknoloji yezixhobo ezipheleleyo

Iseti epheleleyo yezixhobo ibandakanya inkqubo yolawulo lonikezelo lwamandla ngamaxesha aphakathi, inkqubo yokulinganisa iqondo lobushushu be-infrared optical, inkqubo yokulawula ubushushu obuvaliweyo, i-reactive power compensation capacitor bank, induction heat annealing the furnace body, njl.

Inkqubo yolawulo lwamandla aphakathi:

2.3.1 I-intermediate frequency power supply yi-thyristor variable frequency device, i-input voltage i-380V, i-50Hz, kunye namandla aphumayo yi-200KW. Amandla anokulungiswa ngesandla okanye ngokuzenzekelayo ngokweqondo lokushisa elibekiwe. I-frequency yemveliso yi-8KHz (ukulandelela okuzenzekelayo). Umbala wekhabhinethi unqunywe ngokweemfuno zomsebenzisi, ubungakanani benkcazo yi-2000 × 1500 × 1300mm, kwaye ukuphakama kweziko yi-1000mm.

2.3.2 Uhlobo lwe-Cartridge oludibeneyo lwe-silicon rack

I-rectifier kunye ne-inverter inxalenye ye-thyristor ithatha isakhelo se-silicon yamva nje edibeneyo kunye nesicelo selungelo elilodwa lomenzi wechiza. Le ndlela yokufakela yenza i-disassembly kunye nendibano ye-thyristor ibe lula ngakumbi kunye nesayensi. Xa utshintsha i-thyristor, yikhulule nje I-bolt yokuqinisa ingathatha indawo nayiphi na into ye-thyristor ebandleni. Ngaphezu koko, le ndlela yokufakela iyanciphisa ngokupheleleyo umthamo wecandelo le-SCR, elingagcini nje ukwandisa indawo yokusebenza kwikhabhinethi yombane, kodwa iyancipha kakhulu ukulahleka komgca.

2.3.3 Umthamo omkhulu we-DC yokugudisa ireactor

I-reactor egudileyo ibaluleke kakhulu kunikezelo lwamandla aqinileyo, inemisebenzi emibini. Okokuqala, yenza imveliso yangoku ye-rectifier igudile kwaye izinzile. Okwesibini, xa i-inverter thyristor i-short-circuited, izinga lokukhula kwe-short-circuit current kunye nobukhulu bobuninzi be-short-circuit current. Ukuba uyilo lweparameter yesihluzi sereactor alunangqiqo, eyona nto iphambili ayilunganga okanye inkqubo yokuvelisa ayilunganga ngokwaneleyo, iya kuba nempembelelo enkulu ekuthembekeni kokusebenza kobonelelo lwamandla aphakathi.

2.3.4 I-SCR enomthamo omkhulu

Ukuze kuqinisekiswe ukuthembeka kwezixhobo zokusebenza, zombini i-rectifier kunye ne-inverter thyristors zisebenzisa i-Xiangfan isikhululo esisekelwe kwisikhululo esikhulu se-KP kunye ne-silicon ye-KK ukuqinisekisa ukusebenza okuzinzile kwezixhobo.

2.3.5 Sebenzisa iintambo zembuyekezo ezilandelanayo kunye nochungechunge ukunciphisa ilahleko yeentambo zothumelo

Ukuze kuncitshiswe ilahleko kumgca wothumelo lwamaza ombane ophakathi, imbuyekezo ye-capacitor ye-inverter iqhagamshelwe kuthotho kunye nefomu yokuphinda-phindwe kabini yombane.

2.3.6 Iiparamitha zesekethe eziphambili kunye nesiseko sokukhethwa kwecandelo

Imilinganiselo yeeparamitha zesekethe engundoqo yobonelelo lwamandla ombane ophakathi iboniswe kolu luhlu lulandelayo :

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.

Onke amanzi angaphakathi nangaphandle kwe-sensor aqokelelwa kwimigibe emibini yamanzi ensimbi engenasici, edityaniswe kwindawo ephambili yokungena kwamanzi kunye nemibhobho yokuphuma. Umqokeleli wamanzi wensimbi engenasici uyinto enhle kwaye iyasebenza, enokuthintela ngokufanelekileyo impembelelo yokutshatyalaliswa kobushushu bekhoyili ye-induction ngenxa yokubola kombhobho wamanzi kunye nokuvalwa kwendlela yamanzi.
