Ukusebenza ngokungafanelekanga kwesithando sokunyibilikisa i-induction kuya kubangela iingozi ezimandundu

The ukuchithwa kwesithando somlilo ngokwayo lumanyano lweenkqubo ezintathu zombane, amanzi, neoli. Utyando olugwenxa ludla ngokukhokelela kwiingozi ezimandundu. Oku kulandelayo yimisebenzi ethintelwe ngokungqongqo:

(1) Intlawulo engafanelekanga kunye ne-flux yongezwa kwiziko;

(2) Dibanisa intsimbi etyhidiweyo nelinen enesiphene okanye emanzi;

(3) Ilayini yesithando somlilo ifunyaniswa yonakaliswe kakhulu, kwaye ukunyibilikiswa kuyaqhubeka;

(4) Ukutshatyalaliswa komatshini wobundlobongela kwilayini yesithando somlilo;

(5) Iziko libaleka ngaphandle kwamanzi okupholisa;

(6) Isinyithi esinyibilikisiweyo okanye isakhiwo somlilo sisebenza ngaphandle kokumisa;

(7) Ukubaleka phantsi kokhuseleko lombane oluqhelekileyo lokhuselo;

I-Batch alloy, umlinganiselo weqondo lokushisa, ukususwa kwe-slag, njl. Ukuba ezinye zezinto ezikhankanywe ngasentla kufuneka zenziwe ngombane, amanyathelo afanelekileyo okhuseleko kufuneka athathwe, njengokugqoka izicathulo zokukhusela kunye nokugqoka iiglavu ze-asbestos.

Umsebenzi wokulungisa isithando somlilo kunye nezixhobo zayo zombane ezixhasayo kufuneka wenziwe kwimeko yokungaphumeleli kwamandla.

Xa isithando somlilo sisebenza, kuyimfuneko ukubeka iliso ngokucokisekileyo ubushushu besinyithi, umqondiso wengozi, ukushisa kwamanzi okupholisa kunye nesantya sokuhamba ngexesha lenkqubo yokunyibilika. Umbane wamandla wesithando somlilo ulungelelaniswa ukuya ngasentla kwe-0.9, kwaye isigaba sesithathu okanye isigaba sesithandathu sangoku silungelelaniswa ngokusisiseko. Ukushisa kwamanzi okuphuma kwe-sensor, njl. Umda osezantsi wobushushu bamanzi okupholisa ngokubanzi umiselwa kwimeko yokuba akukho ukujiya kwenzeka kudonga lwangaphandle lwenzwa, oko kukuthi, ubushushu bamanzi okupholisa buphezulu kancinane kunobushushu bomoya okhoyo. Ukuba le miqathango ayihlangabezwanga, i-condensation iya kwenzeka kumphezulu we-sensor, kwaye amathuba okuphuka kwenzwa kuya kwanda kakhulu.

Emva kokwakhiwa kweekhemikhali kunye nobushushu bentsimbi etyhidiweyo ihlangabezana neemfuno, amandla kufuneka anqunyulwe kwaye intsimbi kufuneka ifakwe ngexesha.

Ekupheleni komsebenzi wokunyibilikisa, isinyithi esityhidiweyo siphelile. Ukuze kuthintelwe ukupholisa ngokukhawuleza ekwenzeni iintanda ezinkulu kwi-lining yesithando somlilo, amanyathelo afanelekileyo okupholisa acothayo kufuneka athathwe, njengokongeza iipleyiti ze-asbestos kwikhava ye-crucible; umngxuma wempompo uvalwe ngezitena ze-insulation kunye nesanti yemodeli; Umsantsa phakathi kwesigqubuthelo somlilo kunye nomlomo wesithando somlilo uvalwe ngodongwe olukhanyelayo okanye isanti yomfuziselo.

Kwi-crucible induction melting furnaces enomthamo omkhulu, emva komsebenzi wokunyibilikisa, zama ukuphepha ukupholisa okupheleleyo kwesithando somlilo. Ezi ndlela zilandelayo zinokusetyenziswa:

(1) Gcina inxalenye yentsimbi enyibilikisiweyo eziko kwaye unike amandla kumbane ophantsi ukugcina ubushushu bentsimbi etyhidiweyo malunga ne-1300℃;

(2) Fakela i-heater yombane okanye usebenzise isitshizi segesi kwi-crucible ukugcina ubushushu be-crucible lining kwi-900～1100℃;

(3) Emva kokumisa iziko, tywina isigqubuthelo somlilo, kwaye unciphise ngokufanelekileyo ukupholisa kwamanzi okupholisa kwe-inductor, ukuze ucweyo lwesithando somlilo lupholiswe kancinane ukuya kutsho malunga ne-1000 ℃, emva koko ibhloko yentsimbi egalelwe ngokukhethekileyo enemilo efanayo. njengoko i-crucible kodwa incinci ngobukhulu Yixhoma kwiziko, kwaye inike amandla kubushushu ukugcina ubushushu bumalunga ne-1000 ℃. Xa isithando somlilo esilandelayo siqala umsebenzi wokunyibilikisa, ingot isetyenziswa njengefrit.

Ukuba isithando somlilo sidinga ukuvalwa ixesha elide, akukho mfuneko yokugcina i-crucible ifudumele. Ukuze kugcinwe kakuhle i-furnace lining phantsi kweemeko zokupholisa ngokupheleleyo kwamanzi, emva kokuba intsimbi etyhidiweyo kwi-crucible iphelile, i-frit iphakanyisiwe kwaye iqondo lokushisa liyenyuka ukuya kwi-800 ~ 1000 ℃, emva koko isivalo somlilo sivaliwe, amandla. inqunyulwe, kwaye iziko Lifudumele kwaye lipholile ngokucothayo. Ukuqhekeka kuya kubonakala ngokuqinisekileyo kwi-crucible lining emva kokuba isithando somlilo sivaliwe ixesha elide. Xa iphinda inyibilika kwaye isetyenziswa, kufuneka ihlolwe ngononophelo kwaye ilungiswe. Xa unyibilika, iqondo lokushisa kufuneka liphakanyiswe ngokukhawuleza ukwenzela ukuba iincinci ezincinci ezenziwe kwi-lining yesithando somlilo zingavalwa ngokwazo.

Ngethuba lokusebenza kwesithando somlilo, imeko yesithando somlilo kufuneka ihlolwe rhoqo ukuze kuqinisekiswe ukuveliswa okukhuselekileyo kunye nokuphucula ubomi bokukhanya kwesithando somlilo. Iindlela zokusebenza ezingalunganga zihlala zikhokelela ekunciphiseni ubomi bombane wesithando somlilo, ngoko ke ezi mpazamo zilandelayo maziphetshwe:

(1) Ilayini yesithando somlilo ayidityaniswanga, iyabhakwa kwaye itshiswe ngokuhambelana nenkqubo emiselweyo;

(2) Ukuqulunqwa kunye ne-crystal ifom ye-lining material ayifezekisi iimfuno, kwaye iqulethe ukungcola okungakumbi

(3) Ubushushu obugqithisileyo bentsimbi enyibilikisiweyo kwinqanaba lamva lokunyibilikiswa bungaphezulu koluhlu oluvumelekileyo;

(4) Ukusebenza okungachanekanga kunye nokutshatyalaliswa komatshini wobundlobongela kusetyenziswe xa kulayishwa izinto eziqinileyo okanye ibhuloho ngenxa yokukhutshwa kwezinto zokutshisa, okwenza umonakalo omkhulu kwi-crucible lining;

(5) Emva kokuba isithando somlilo sivaliwe, intambo yesithando somlilo iyacinywa kwaye kwenzeka iintanda ezinkulu.

Ukuba isithando somlilo siphazamiseka, inani lamanzi okupholisa inzwa lingancitshiswa ngokufanelekileyo, kodwa akuvumelekanga ukucima amanzi okupholisa, ngaphandle koko ukushisa okushiyekileyo kwesithando somlilo kunokutshisa i-insulation layer ye-sensor. Kuphela xa iqondo lokushisa elingaphezulu kwesithando somlilo liwela ngaphantsi kwe-100 ° C, amanzi okupholisa we-inductor angacinywa.
