Isithando somlilo esiphakathi iimfuno zobugcisa

1. Thyristor intermediate frequency inverter :

1.1 Ngomsebenzi wokuqalisa obandayo wesithando somlilo, qalisa izinga lokuphumelela: 100%; izinto ezishushu 100%. Isithando somlilo siqala ukutshisa into yesithathu ukufikelela kwiqondo lokushisa. Kwaye inokubunjwa ukuya kwimathiriyeli yokugqibela.

1.2 Umbane uxhotyiswe ngamacandelo e-500 kw , kwaye ukugqithiswa kuvunyelwe ukuba kube yi-20 % ixesha elifutshane .

I-1.3 inikwe amandla emveliso ye-500 kw eqhuba amandla angaphezulu kwe-0.9.

1.4 Amacandelo aphambili afana ne-thyristors kwikhabhinethi ye-inverter ye-IF kunye namacandelo aphambili omgca wonke kukhethwa ukuba angeniswe kumazwe angaphandle okanye asekhaya aziwayo aphambili kwizixhobo eziphambili. Zonke iinxalenye zoyilo kufuneka zitshintshwe kwinqanaba elinye ngenxa yobunzima bokuthengwa kwempahla, ukuqinisekisa ukusebenza okuzinzile nokuthembekileyo kwezixhobo.

I-1.5 i-interfrequency induction heater inomsebenzi wokugcina ubushushu (umsebenzi ophantsi oqhelekileyo wonikezelo lwamandla ombane ophakathi).

1.6 Emva kokufudumeza, iindawo ezingenanto ezahlukeneyo zifikelela kwiqondo lokushisa kwenkqubo yezinto ezahlukeneyo ( 1150 ° C ), kwaye izinto eziphathekayo azibambeli.

1.7 Ubume beSekethe: i-inverter ehambelanayo.

1.8 Kwimeko yokuguquguquka kwamandla ombane kwigridi ye-15%, ukuguquguquka kwamandla ombane we-IF akukho ngaphezu kwe- ± 1%.

I-1.9 i-brass dual reactor configuration, exhunywe kwindawo yangaphakathi ye-cross-sectional yobhedu inkulu ngokwaneleyo ukunciphisa umkhuhlane.

2.Induction heater:

2.1 Ubushushu obufanayo: Umahluko weqondo lokushisa kwi-heart surface ye-billet iyancitshiswa ibe yincinci xa ikhutshwa.

2.2 I-sensor yenziwe nge-knotting ephezulu, kwaye ubomi obuqhelekileyo bekhoyili ye-sensor ingaphezulu kweminyaka emi-3. I-sensor lining inobomi benkonzo obuqhelekileyo obungaphezulu konyaka omnye.

2.3 Umzila wesikhokelo sangaphakathi we-sensor unempahla yokunxiba.

2.4 usebenzisa i-inductor design parallel, i-blank inyuka ngokuthe ngcembe ukusuka ekupheleni kwesondlo ukuya kwiqondo lokushisa lokukhutshwa ukuze kuqinisekiswe ukuba i-blank ayivelisi i-micro-cracks kwinkqubo yokufudumeza, ukushisa okugqithiseleyo kunye nezinye iziphene.

2.5 Ikhoyili ye-inductor, ibha yebhasi kunye neengcingo zokudibanisa zinendawo enkulu enqamlezileyo ukunciphisa ukuvelisa ubushushu.

2.6 Uxhulumaniso lwangaphakathi lwekhoyili ye-inductor lunokuthenjwa, i-inductor yenziwe ngokungqongqo ngokweemfuno zenkqubo, kwaye uvavanyo oluvuzayo oluphezulu lwenziwa ngaphambi kokuhlanganisana.

3. Inkqubo yokulawula ubushushu

3.1 Isilinganisi-manzi:

3.1.1 Ithemometha ye-infrared yaseMelika iRaytheon inokusetyenziselwa ukubamba okuphezulu kunye nokusetha ngokutsha okuzenzekelayo. Kuluhlu lwe-1150 °C, impazamo yokulinganisa ubushushu ayikho ngaphezu kwe-± 0.3%, kwaye ukuchaneka okuphindaphindiweyo akukho ngaphezu kwe-± 0.1%.

3.1.2 Isixhobo sokulinganisa ubushushu asichatshazelwa sisikali se-oxide engaphezulu, uthuli, umsi kunye nomphunga wamanzi.

3.1.3 Seta ithemometha kwindawo yokukhupha ukuqinisekisa ukuba amandla olawulo oluvaliweyo;

I-3.2 Isixhobo sokulawula: Inkqubo yokulawula ukushisa inomsebenzi wokulungiswa kwe-“PID” kunye nokulawulwa kwe-loop evaliweyo yokushisa kwesithando somlilo.

Umgaqo wolawulo lwenkqubo:

Ulawulo lolawulo lwamandla ngexesha lokufudumeza :

Kwinkqubo yokufudumala i-workpiece, ukulungiswa kwamandla kusekelwe ikakhulu kwizinto ezimbini.

Iqondo lokushisa lilawulwa kwi-loop evaliweyo ngokuhambelana neqondo lokushisa lokucofa.

Ngokwemfuno yokubetha i-workpiece, imfuno yesantya idibene nokulungiswa kwe-loop evaliweyo yamandla.

4. Inkqubo yolawulo lombane:

4.1 Isethi epheleleyo yezixhobo ingalawulwa phambi kwekhabhinethi yokulawula okanye kwindawo yokusebenza.

4.2 inokuqonda imowudi yokusebenza ngokuzenzekela ngokupheleleyo, isemi-automatic, manual.

I-4.3 Inxalenye yokulawula Yongeza i-PLC kwi-interface yomshini womntu, iiparamitha zeseti ngexesha langempela, ukubonisa amandla, i-voltage, yangoku, iqondo lokushisa kunye nezinye iiparitha, enembile kwaye enokwethenjelwa.

5. Amanyathelo okhuseleko:

5.1 Izixhobo zokudibanisa izixhobo zombane zixhotyiswe ngezilumkiso eziyimfuneko (iimpawu zombane, izilumkiso, izahlulo, njl.), ukukhuselwa kunye nokukhusela ukukhusela ukugcinwa kunye nokhuseleko lomsebenzisi.

5.2 Ukusebenza okudibeneyo kunye nokukhuselwa kwayo yonke iseti; Ukumisa okungxamisekileyo, ngaphezulu kwamandla ombane, ngaphezulu kwangoku, ilahleko yesigaba, ukusilela kwe-inverter, ukucinywa kwamandla ombane, ukucinywa kwamandla ombane, ukucuthwa kwangoku, ubushushu obungaphezulu kwamalungu naphantsi koxinzelelo kunye nokupholisa inkqubo yokupholisa, ubushushu bamanzi aphezulu (amanzi abuyayo ngalinye) Onke amasebe axhotyiswe ngophawu lobushushu. ), kunye nenkqubo elandelayo (ngaphantsi kwemizuzu eyi-15 yokunciphisa amandla esiphoso, ngaphezu kwemizuzu eyi-15 yokuvala i-faultdown) kunye nokunye ukudibanisa, i-alarm yephutha, ukuxilongwa kwephutha, njl., ukusebenza okupheleleyo, okuthembekileyo. Kuqinisekisiwe ukuba izixhobo aziyi konakaliswa, kwaye ukungaphumeleli kwezinto ezibonakalayo kwi-heater induction kunye nokhuseleko lomntu luya kwenzeka.

5.3 Iyonke isethi yezixhobo inokuthenjwa kwaye inexesha elifanelekileyo, elinokuthi lithintele ngokufanelekileyo umonakalo obangelwa kukusetyenziswa kakubi kwezixhobo kunye nomzimba womntu.

5.4 Ukwenziwa kunye nofakelo lwenziwa ngokuhambelana neMigangatho yoVavanyo loKhuseleko lweShishini loShishino loMphathiswa woShishino loShishino.

I-5.5 Yenziwe ngokuhambelana nomgangatho wesizwe wokufudumala kwesithando somlilo kwaye ihlangabezana nemigangatho yelizwe yokhuseleko lokusingqongileyo kunye nemigangatho yokhuseleko.
