Ukusebenza okungalungile kwesithando somlilo esincibilikisayo kuzodala izingozi ezimbi

The ukuchithwa kwesithando somlilo ngokwayo iwubunye bezinhlelo ezintathu zikagesi, amanzi, namafutha. Ukuhlinzwa okungajwayelekile kuvame ukuholela ezingozini ezimbi kakhulu. Lokhu okulandelayo kuyimisebenzi enqatshelwe ngokuphelele:

(1) Inkokhelo engafanelekile kanye nokugeleza kwamanzi kwengezwa esithandweni;

(2) Xhuma insimbi encibilikisiwe nelineni elingasebenzi kahle noma elimanzi;

(3) Ulayini lwesithando somlilo lutholakala lonakaliswe kakhulu, futhi ukuncibilika kuyaqhubeka;

(4) Ukushaqeka okunamandla kolwelwesi lwesithando somlilo;

(5) Isithando somlilo sihamba ngaphandle kwamanzi apholisayo;

(6) Insimbi encibilikisiwe noma isakhiwo somzimba wesithando somlilo sisebenza ngaphandle kokuphansi;

(7) Isebenza ngaphansi kokuvikelwa okujwayelekile kokuphepha kukagesi;

(8) Uma isithando somlilo singanikiwe amandla, faka ukushaja, ukushaja okuqinile, ukuthatha amasampula, kanye nokwengeza.

Ingxubevange yenqwaba, ukulinganisa izinga lokushisa, ukususwa kwe-slag, njll. Uma eminye yale misebenzi eshiwo ngenhla kufanele yenziwe ngogesi, kufanele kuthathwe izinyathelo ezifanele zokuphepha, njengokugqoka izicathulo ezivikelayo nokugqoka amagilavu ​​e-asbestos.

Umsebenzi wokulungisa isithando somlilo kanye nemishini kagesi esekelayo kufanele wenziwe esimweni sokuhluleka kwamandla.

Lapho isithando somlilo sisebenza, kuyadingeka ukuqapha ngokucophelela izinga lokushisa lensimbi, isignali yengozi, ukushisa kwamanzi okupholisa kanye nezinga lokugeleza ngesikhathi senqubo yokuncibilika. Isici samandla esithandweni somlilo silungiswa sibe ngaphezu kuka-0.9, futhi isigaba sesithathu noma isigaba sesithupha samanje silingana ngokuyisisekelo. Izinga lokushisa lokuphuma kwamanzi lenzwa, njll. alidluli inani eliphakeme elishiwo kumklamo. Umkhawulo ophansi wezinga lokushisa lamanzi okupholisa ngokuvamile unqunywa esimweni sokuthi akukho ukuminyana okwenzeka odongeni olungaphandle lwenzwa, okungukuthi, izinga lokushisa lamanzi okupholisa liphakeme kancane kunezinga lokushisa lomoya elizungezile. Uma lezi zimo zingahlangatshezwana nazo, ukufiphala kuzokwenzeka ebusweni benzwa, futhi amathuba okuphuka kwezinzwa azokhula kakhulu.

Ngemuva kokuthi ukwakheka kwamakhemikhali kanye nezinga lokushisa kwensimbi encibilikisiwe kuhlangabezana nezidingo, amandla kufanele anqanyulwe futhi insimbi kufanele ithintwe ngesikhathi.

Ekupheleni komsebenzi wokuncibilikisa, insimbi encibilikisiwe iyaphela. Ukuze kuvinjwe ukupholisa ngokushesha ukuthi kungakhi imifantu emikhulu olayini lwesithando somlilo, kufanele kuthathwe izinyathelo ezifanele zokupholisa kancane, njengokwengeza amapuleti e-asbestos embozweni yokubhoboza; imbobo kampompi ivinjwe ngezitini zokufakelwa kanye nesihlabathi sokufanisa; Igebe phakathi kwesembozo sesithando somlilo kanye nomlomo wesithando somlilo livalwe ngobumba oluphikisayo noma isihlabathi esiyimodeli.

Ezithandweni zokuncibilika ze-crucible induction ezinomthamo omkhulu, ngemva kokusebenza kokuncibilikisa, zama ukugwema ukupholisa okuphelele kolwelwesi lwesithando somlilo. Kungasetshenziswa izindlela ezilandelayo:

(1) Gcina ingxenye yensimbi encibilikisiwe esithandweni futhi unikeze amandla ku-voltage ephansi ukuze ugcine izinga lokushisa lensimbi encibilikisiwe licishe libe ngu-1300 ℃;

(2) Faka i-heater kagesi noma usebenzise isishisi segesi ku-crucible ukuze ugcine izinga lokushisa lolwelwesi lwama-crucible liku-900～1100℃;

(3) Ngemuva kokumisa isithando somlilo, vala ikhava yesithando somlilo, futhi unciphise ngokufanelekile ukugeleza kwamanzi okupholisa kwe-inductor, ukuze ulwelwesi lwesithando somlilo lupholiswe kancane kancane lufinyelele cishe ku-1000 ℃, bese kuba i-cast cast iron block enesimo esifanayo. njenge-crucible kodwa encane ngosayizi Ngena esithandweni, futhi unikeze amandla ekushiseni ukugcina izinga lokushisa licishe libe ngu-1000 ℃. Lapho isithando somlilo esilandelayo siqala umsebenzi wokuncibilikisa, ingot isetshenziswa njenge-frit.

Uma isithando somlilo sidinga ukuvalwa isikhathi eside, asikho isidingo sokugcina i-crucible ifudumele. Ukuze ugcine kangcono ulayini lwesithando somlilo ngaphansi kwesimo samanzi apholisa ngokuphelele, ngemuva kokuthi insimbi encibilikisiwe e-crucible isiphelile, i-frit iphakanyiselwe ngaphakathi futhi izinga lokushisa likhuphukela ku-800 ~ 1000 ℃, khona-ke ikhava yesithando somlilo ivaliwe, amandla. iyanqunywa, futhi isithando somlilo Sifudumele futhi sipholile kancane. Imifantu izovela nakanjani kulwelwesi lwe-crucible ngemva kokuba isithando somlilo sivaliwe isikhathi eside. Uma iphinde yancibilika futhi isetshenziswa, kufanele ihlolwe ngokucophelela futhi ilungiswe. Lapho kuncibilika, izinga lokushisa kufanele liphakanyiswe kancane ukuze imifantu emincane eyenziwe olayini besithando somlilo ivaleke ngokwayo.

Ngesikhathi sokusebenza kwesithando somlilo, isimo sesithando somlilo kufanele sihlolwe njalo ukuze kuqinisekiswe ukukhiqizwa okuphephile nokuthuthukisa impilo yomlilo wesithando somlilo. Izindlela zokusebenza ezingalungile zivame ukuholela ekunciphiseni ukuphila kolayini lwesithando somlilo, ngakho-ke amaphutha alandelayo avamile kufanele agwenywe:

(1) Ulayini lwesithando somlilo alufindo, lubhakwa futhi lushiswe ngokuhambisana nenqubo enqunyiwe;

(2) Ukwakheka kanye nohlobo lwekristalu lwento yolwelwesi olungahlangabezani nezimfuneko, futhi luqukethe ukungcola okwengeziwe

(3) Izinga lokushisa elishisisa ngokweqile lensimbi encibilikisiwe esigabeni sakamuva sokuncibilika lingaphezu kwebanga elivumelekile;

(4) Ukusebenza okungalungile kanye nokushaqeka komshini okunobudlova kwasetshenziswa lapho kulayishwa izinto eziqinile noma ibhuloho ngenxa yokukhipha izinto zesithando somlilo, okubangela umonakalo omkhulu kulwelwesi olucibilikayo;

(5) Ngemva kokuba isithando somlilo sivaliwe, ulwelwesi lwesithando somlilo luyacishwa futhi kube nemifantu emikhulu.

Uma isithando somlilo siphazamiseka, inani lamanzi okupholisa inzwa lingancishiswa ngokufanele, kodwa akuvunyelwe ukuvala amanzi okupholisa, ngaphandle kwalokho ukushisa okusalayo komugqa wesithando somlilo kungashisa isendlalelo sokufakelwa kwenzwa. Kuphela lapho izinga lokushisa elingaphezulu lendwangu yesithando somlilo lehla ngaphansi kwe-100 ° C, amanzi okupholisa we-inductor angavalwa.
