Ukusetshenziswa nokugcinwa ngendlela efanelei-silicon carbide crucibleszidlala indima ebalulekile ekuphileni kwabo isikhathi eside nempumelelo. Nazi izinyathelo ezinconyiwe zokufaka, ukushisa kuqala, ukushaja, ukususwa kwe-slag, nokugcinwa kwangemuva kokusetshenziswa kwalezi zinsimbi.
Ukufakwa kwe-Crucible:
Ngaphambi kokufaka, hlola isithando somlilo futhi ubhekane nanoma yiziphi izinkinga zesakhiwo.
Sula noma yiziphi izinsalela ezindongeni zesithando somlilo naphansi.
Qinisekisa ukusebenza kahle kwezimbobo zokuvuza futhi usule noma yikuphi ukuvimba.
Hlanza isishishi futhi uqinisekise ukuma kwaso okulungile.
Uma konke ukuhlola okungenhla sekuqediwe, beka i-crucible phakathi nendawo yesisekelo sesithando somlilo, uvumele igebe elingu-2 kuya ku-3-intshi phakathi kwe-crucible nezindonga zesithando somlilo. Impahla engezansi kufanele ifane ne-crucible material.
Ilangabi lokushisa kufanele lithinte ngokuqondile i-crucible endaweni ehlangene nesisekelo.
I-Crucible Preheating: Ukushisa kwangaphambili kubalulekile ukuze kunwetshwe isikhathi sempilo ye-crucible. Izigameko eziningi zokulimala kwe-crucible zenzeka phakathi nesigaba sokushisa, okungenzeka kungabonakali kuze kube yilapho inqubo yokuncibilika kwensimbi iqala. Landela lezi zinyathelo zokushisisa kwangaphambilini okufanele:
Ukuze uthole ama-crucible amasha, kancane kancane wandise izinga lokushisa ngo-100-150 degrees Celsius ngehora lize lifinyelele cishe ku-200 ° C. Gcina lokhu kushisa imizuzu engu-30, bese ukunyusa kancane kancane ku-500 ° C ukuze ususe noma yikuphi umswakama omuncwe.
Okulandelayo, shisisa i-crucible ibe ngu-800-900 ° C ngokushesha ngangokunokwenzeka bese wehlisela ezingeni lokushisa elisebenzayo.
Uma izinga lokushisa le-crucible lifinyelela ebangeni lokusebenza, engeza inani elincane lempahla eyomile ku-crucible.
Ukushaja I-Crucible: Izindlela zokushaja ezifanele zifaka isandla ekuphileni isikhathi eside kwe-crucible. Gwema ukubeka ama-ingots ensimbi abandayo ngokuvundlile noma ukuwaphonsa ku-crucible ngaphansi kwanoma yiziphi izimo. Landela le mihlahlandlela yokushaja:
Sula ama-ingots ensimbi namaqatha amakhulu ngaphambi kokuwangeza ku-crucible.
Beka izinto zensimbi ngokukhululekile ku-crucible, uqale ngezingcezu ezincane njenge-cushion bese wengeza izingcezu ezinkulu.
Gwema ukungeza ama-ingots amakhulu ensimbi enanini elincane lensimbi ewuketshezi, njengoba kungase kubangele ukupholisa okusheshayo, kuphumele ekuqinisweni kwensimbi kanye nokuqhekeka okungahle kube nokuqhekeka.
Hlanza i-crucible yayo yonke insimbi ewuketshezi ngaphambi kokuvala noma phakathi nekhefu elinwetshiwe, njengoba ama-coefficients ahlukene okunweba we-crucible nensimbi angase aholele ekuqhekekeni ngesikhathi sokushisisa kabusha.
Gcina izinga lensimbi encibilikisiwe ku-crucible okungenani u-4 cm ngaphansi kwaphezulu ukuze uvimbele ukuchichima.
Ukususwa kwe-Slag:
Engeza ama-ejenti asusa i-slag ngokuqondile ensimbi encibilikisiwe futhi ugweme ukuwethula ku-crucible engenalutho noma ukuwaxuba neshaje yensimbi.
Gcoba insimbi encibilikisiwe ukuze uqinisekise ngisho nokusatshalaliswa kwama-ejenti asusa i-slag futhi uwavimbele ekuphenduleni ngezindonga ze-crucible, njengoba lokhu kungabangela ukugqwala nokulimala.
Hlanza izindonga zangaphakathi eziqinile ekupheleni kosuku ngalunye lomsebenzi.
Ukugcinwa Kwangemuva Kokusetshenziswa Kwe-Crucible:
Thulula insimbi encibilikisiwe ku-crucible ngaphambi kokuvala isithando somlilo.
Ngenkathi isithando somlilo sisashisa, sebenzisa amathuluzi afanelekile ukuze usule noma iyiphi i-slag enamathela ezindongeni eziboshiwe, uqaphele ukuthi ungalimazi i-crucible.
Gcina izimbobo zokuvuza zivaliwe futhi zihlanzekile.
Vumela i-crucible ukuthi iphole ngokwemvelo ekamelweni lokushisa.
Ezikhiqizweni ezisetshenziswa ngezikhathi ezithile, zigcine endaweni eyomile futhi evikelekile lapho mancane amathuba okuthi ziphazamiseke.
Bamba ama-crucibles ngobumnene ukuze ugweme ukuphuka.
Gwema ukubeka i-crucible emoyeni ngokushesha ngemva kokushisa, njengoba lokhu kungase kubangele
