Ukufudumeza okuphakathi kwamaza okwenziwa izixhobo zethusi zobhedu annealing

1 , Isishwankathelo:

I-intermediate frequency induction yokufudumeza ityhubhu yobhedu (ityhubhu yobhedu) izixhobo zokufunxa zilungele ukuqhotyoshwa kwe-intanethi yeetyhubhu zobhedu (i-alloy sheath yangaphandle yobhedu). Ubunzulu bokungena kunye nobunzima buhambelana neemfuno ezithile zabathengi ukuphumeza ukususwa koxinzelelo kunye nokuthotywa kwee-alloys zobhedu. Injongo yesingxobo sangaphandle.

Intshayelelo yezixhobo Iseti epheleleyo yezixhobo ziyilwe kwaye zenziwe ngokuhambelana nesakhiwo se-mechatronics. Phakathi kwazo, unikezelo lwamandla ombane oluphakathi luseti ye-6- pulse thyristor KGPS200KW/8KHZ unikezelo lwamandla ombane oluphakathi, umthwalo iseti ye-GTR yochungechunge lokufudumeza isithando somlilo, kunye nesixhobo sixhotyiswe ngeseti ye-capacitor bank yembuyekezo yamandla esebenzayo. . Isixhobo senziwe ngamaqhina okulungelelaniswa okwenziwa ngesandla kunye ngokuzenzekelayo, phakathi kwawo ngokuzenzekelayo yimo yokulawula ubushushu obuvaliweyo. Ikhonsoli yokulawula yangaphandle ithatha i-PLC (i-Siemens) kunye nokulawula isikrini sesikrini. Iiparamitha zokufudumeza zinokufakwa ngokulula kwisikrini sokuchukumisa, njengokucaciswa kwetyhubhu yobhedu, isantya sokufudumeza, ubushushu be-annealing, njl.njl , ngokwenjenjalo Dibana neemfuno zemveliso. Xa inxalenye ethile yemveliso ingaphumeleli, unikezelo lwamandla ombane oluphakathi lunokugqunywa ngokweqondo lobushushu elibekiweyo ukuphepha ukutshisa kakhulu ityhubhu yobhedu. Izixhobo zibekwe ngokweemfuno zomsebenzisi, zijongene nezixhobo ukusuka kwesobunxele ukuya ngasekunene, itafile yokusebenza ibekwe ngokubhekiselele kwisixhobo esiphambili, esilungele umqhubi ukuba aqaphele imeko yokuvelisa kunye nokuququzelela ukulungiswa kweeparitha.

Ukhuseleko lokhuseleko Isixhobo sinemilinganiselo yokhuseleko olupheleleyo, njengokhuseleko lokunqongophala kwamanzi, ukukhuselwa kwesigaba, ukhuseleko lwangoku, ukukhuselwa kwamandla ombane, ukukhuselwa kwamandla ombane, ukhuseleko lwamanzi aphezulu, njl. iimpazamo. Izixhobo ziqwalaselwe ngokwe-200KW, zishiya umda wamandla okwaneleyo ukuqinisekisa ukuveliswa okuqhubekayo kunye nokuzinza kwezixhobo zeeyure ze-24. Zonke ii-conductors eziveziweyo zifakwe kwibhokisi yokulawula yombane kunye nesitshixo, kwaye kukho izikhumbuzo ezikhuselekileyo zokukhusela amehlo, ngoko akukho zingozi zokhuseleko zombane ziya kwenzeka. Isixhobo ngasinye esidibeneyo sinokuphepha umonakalo kwisixhobo okanye umbhobho wobhedu ngenxa ye-misoperation manual.

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.

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 Large-capacity DC smoothing reactor

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 :

2.3. Izixhobo ezi-6 zokufudumeza ityhubhu yobhedu

I-inductor yenziwe ngegobolondo lesithando somlilo, i-coil induction, umqokeleli wamanzi wensimbi engenasici kunye nesithando somlilo. I-coil induction idibene kunye neeparitha zombhobho we-alloy annealed copper ukuze kulungiswe uyilo kunye nesoftware ekhethekileyo yekhompyuter kwaye uyenze idityaniswe namava angempela. Inokuqinisekisa eyona nto isebenzayo yokudibanisa i-electromagnetic phantsi komthamo ofanayo. Iikhoyili zokungeniswa kunye ne-99.99% ye-T2 unxande wobhedu ojikelezayo owenziweyo, i-coil insulating yangaphandle yokukhusela inkqubo yokutshiza i-epoxy resin insulating layer yamandla aphezulu, umaleko wokugquma uxinzelelo mkhulu kune-5000V.

Uluhlu lwangaphakathi lwekhoyili ye-induction yenziwe nge-white corundum lining, kwaye ngaphandle kwe-lining kunye naphakathi kwee-coil ziqiniswe nge-cement refractory (i-American Union Mine), enokudlala indima kwi-insulation kunye nokugcinwa kobushushu. Ngelo xesha, amandla ombane omhlophe we-corundum ayanda ngakumbi, ukuphepha ngokufanelekileyo imibhobho yobhedu ekulimazeni umgca.

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.
