Isithando sokushisa esiphakathi nendawo izidingo zobuchwepheshe

1. I-inverter ye-Thyristor intermediate frequency :

1.1 Ngomsebenzi wokuqalisa obandayo wesithando somlilo, izinga lempumelelo yokuqala: 100 %; izinto ezishisayo 100%. Isithando somlilo siqala ukushisa into yesithathu ukuze sifinyelele izinga lokushisa lenqubo. Futhi kungenziwa kwakhiwa kuze impahla yokugcina.

1.2 Ukunikezwa kwamandla kufakwe izingxenye ze-500 kw , futhi ukulayishwa ngokweqile kuvunyelwe ukuthi kube ngu – 20 % okwesikhashana .

1.3 amandla okukhiphayo alinganiselwe angu-500 kw agijima isici samandla angaphezu kuka-0.9.

1.4 Izingxenye eziyinhloko ezifana nama-thyristors kukhabhinethi ye-inverter ye-IF kanye nezingxenye eziyinhloko zawo wonke ulayini kungcono zingeniswe zisuka kumadivayisi athuthukile aphesheya noma asekhaya adumile. Zonke izingxenye zokuklama zidinga ukushintshwa ngezinga elilodwa ngenxa yobunzima bokuthengwa kwempahla, ukuqinisekisa ukusebenza okuzinzile nokuthembekile kwemishini.

I-1.5 medium frequency induction heater inomsebenzi wokugcina ukushisa (ukusebenza kwemvamisa ephansi yokunikezwa kwamandla okuvama okuphakathi).

I-1.6 Ngemuva kokushisa, izikhala ezihlukahlukene zifinyelela ekushiseni kwenqubo yezinto ezahlukene ( 1150 ° C ), futhi impahla ayinamathele.

1.7 Isakhiwo sesekhethi: inverter ehambisanayo.

1.8 Esimeni sokuguquguquka kwamandla kagesi wegridi ka-15 %, ukushintshashintsha kwamandla kagesi we-IF akudluli ku-± 1%.

1.9 ukucushwa kwe-brass dual reactor, exhunywe endaweni yangaphakathi ye-cross-sectional yethusi kukhulu ngokwanele ukunciphisa ukushisa.

2.Induction heater:

2.1 Ukufana kwezinga lokushisa: Umehluko wezinga lokushisa lendawo yenhliziyo ye-billet wehliswa ube ubuncane uma ukhishwa.

2.2 Inzwa yenziwe nge-knotting yekhwalithi ephezulu, futhi impilo evamile yekhoyili yezinzwa ingaphezu kweminyaka emi-3. I-sensor lining inokuphila kwesevisi evamile okungaphezu konyaka owodwa.

2.3 Umzila wesitimela wangaphakathi wenzwa unezinto ezingagugi.

2.4 kusetshenziswa idizayini ye-inductor ehambisanayo, okungenalutho kuyanda kancane kancane ukusuka ekugcineni kokuphakelayo kuya kumazinga okushisa okukhipha ukuze kuqinisekiswe ukuthi okungenalutho akukhiqizi imifantu emincane enqubweni yokushisisa, ukushiswa kwezinga lokushisa ngokweqile nokunye ukonakala.

2.5 Ikhoyili ye-inductor, ibha yebhasi nezintambo ezixhuma kunendawo enkulu enqamulelayo ukunciphisa ukukhiqizwa kokushisa.

2.6 Uxhumo lwangaphakathi lwekhoyili ye-inductor luthembekile, i-inductor yakhiwe ngokuqinile ngokuvumelana nezidingo zenqubo, futhi ukuhlolwa kokuvuza komfutho ophezulu kwenziwa ngaphambi kokuhlanganisa.

3. Uhlelo lokulawula izinga lokushisa

3.1 I-thermometer:

3.1.1 Ithemometha ye-Raytheon ye-infrared yaseMelika ingasetshenziselwa ukubamba okuphezulu nokusetha kabusha okuzenzakalelayo. Kububanzi obungu-1150 °C, iphutha lokulinganisa izinga lokushisa alikho ngaphezu kuka-± 0.3% , futhi ukunemba okuphindayo akungaphezu kuka-± 0.1%.

3.1.2 Ithuluzi lokulinganisa izinga lokushisa alithintwa isikali se-surface oxide, uthuli, intuthu nomhwamuko wamanzi.

3.1.3 Setha ithemometha endaweni yokukhipha amanzi ukuze uqinisekise amandla okulawula iluphu;

3.2 Ithuluzi lokulawula: Isistimu yokulawula izinga lokushisa inomsebenzi wokulungisa we-“PID” kanye nokulawula okuyiluphu evaliwe kwezinga lokushisa lesithando somlilo.

Isimiso sokulawula isistimu:

Ukulawula ukulawulwa kwamandla ngesikhathi sokushisisa :

Enkambweni yokushisa i-workpiece, ukulungiswa kwamandla kusekelwe ikakhulukazi ezintweni ezimbili.

Izinga lokushisa lilawulwa ku-loop evaliwe ngokuvumelana nezinga lokushisa elibekiwe lokuthepha.

Ngokusho kwemfuneko yebhithi egijimayo ye-workpiece, imfuneko yesivinini ihlangabezana nokulungiswa kwe-loop evaliwe yamandla.

4. Uhlelo lokulawula ugesi:

4.1 Isethi ephelele yemishini ingalawulwa phambi kwekhabhinethi yokulawula noma endaweni yokusebenza.

I-4.2 ingakwazi ukubona imodi yokusebenza ngokuzenzakalelayo ngokuphelele, i-semi-automatic, manual.

4.3 Ingxenye yokulawula Engeza i-PLC kusixhumi esibonakalayo somshini womuntu, setha imingcele ngesikhathi sangempela, amandla okubonisa, i-voltage, yamanje, izinga lokushisa kanye neminye imingcele, enembile futhi enokwethenjelwa.

5. Izinyathelo zokuphepha:

5.1 Izingxenye zokuxhuma zikagesi ezisetshenziswayo zifakwe izexwayiso ezidingekayo (izimpawu zombani, izexwayiso, ama-partitions, njll.), ukuvikelwa nokuvikela ukuvikela ukugcinwa nokuphepha komqhubi.

5.2 Ukusebenza okuxhumene nokuvikela kwayo yonke isethi; ukumisa izimo eziphuthumayo, i-voltage engaphezu kwamandla, phezu kwamanje, ukulahleka kwesigaba, ukwehluleka kwe-inverter, ukunqanyulwa kwe-voltage, ukunqamuka kwamanje, izinga lokushisa elingaphezulu kwezingxenye nangaphansi kwengcindezi nokupholisa uhlelo lokupholisa, izinga lokushisa eliphezulu lamanzi (amanzi abuyayo ngalinye) Wonke amagatsha ahlonyiswe ukuthola izinga lokushisa. ), kanye nenqubo elandelayo (imizuzu engaphansi kwe-15 yokunciphisa amandla wephutha, imizuzu engaphezu kwe-15 yokuvala iphutha) nokunye okuhlanganisiwe, i-alamu yephutha, ukuxilongwa kwephutha, njll, ukusebenza okuphelele, okuthembekile. Kuqinisekisiwe ukuthi imishini ngeke yonakaliswe, futhi ukwehluleka kwezinto ezibonakalayo ku-heater yokungeniswa nokuphepha komuntu kuzokwenzeka.

5.3 Isethi yonke yezinto ezisetshenziswayo ithembekile futhi inesikhathi esiphusile, engagwema ngempumelelo umonakalo odalwe ukusetshenziswa kabi kwemishini nomzimba womuntu.

5.4 Ukukhiqiza nokufaka kwenziwa ngokuvumelana Namazinga Okuhlola Ukuphepha Kwemboni Yemishini Yomnyango Wemboni Yemishini.

5.5 Ikhiqizwa ngokwezinga likazwelonke lokushisisa isithando somlilo futhi ihlangabezana namazinga kazwelonke okuvikelwa kwemvelo kanye nokuphepha.
