Ukusetyenziswa ngokufanelekileyo kunye nokugcinwa kweiicrucibles ze-silicon carbidezidlala indima ebalulekileyo kubomi obude nokusebenza kwazo.Nazi iindlela ezicetyiswayo zokufakela, ukufudumala, ukutshaja, ukususwa kwe-slag, kunye nokugcinwa kokusetyenziswa emva kokusetyenziswa kwezi crucibles.
Ukufakelwa kweCrucible:
Ngaphambi kokufakela, jonga isithando somlilo kwaye ulungise nayiphi na imiba yesakhiwo.
Sula nayiphi na intsalela kwiindonga zesithando somlilo kunye nezantsi.
Qinisekisa ukusebenza ngokufanelekileyo kwemingxuma yokuvuza kwaye ucime nayiphi na imiqobo.
Coca isitshisi kwaye uqinisekise indawo ekuso echanekileyo.
Emva kokuba zonke iitshekhi ezingentla zigqityiwe, faka i-crucible embindini wesiseko sesithando somlilo, uvumele i-gap ye-2 ukuya kwi-3-intshi phakathi kwe-crucible kunye neendonga zesithando somlilo.Izinto ezisezantsi kufuneka zifane nezixhobo ezinqamlekileyo.
Umlilo ovuthayo kufuneka uthinte ngqo i-crucible kwindawo edibeneyo kunye nesiseko.
I-Crucible Preheating: Ukushisa kwangaphambili kubalulekile ukwandisa ubomi be-crucible.Iziganeko ezininzi zomonakalo we-crucible zenzeka ngexesha lesigaba sokufudumeza, esinokuthi singabonakali de kube inkqubo yokunyibilika kwesinyithi iqala.Landela la manyathelo ukulungiselela ukufudumeza kwangaphambili:
Kwiicrucibles ezitsha, ngokuthe ngcembe wandise ubushushu nge-100-150 degrees celsius ngeyure de bufikelele kuma-200°C.Gcina obu bushushu imizuzu engama-30, uze unyuse kancinane ukuya kuma-500°C ukususa nakuphi na ukufuma okufunliweyo.
Emva koko, fudumeza i-crucible ukuya kwi-800-900 ° C ngokukhawuleza kwaye uyihlise kwiqondo lokushisa lokusebenza.
Emva kokuba ubushushu be-crucible bufikelele kuluhlu lokusebenza, yongeza izinto ezincinci zezinto ezomileyo kwi-crucible.
Ukutshaja i-Crucible: Iindlela ezifanelekileyo zokutshaja zinegalelo kubomi obude be-crucible.Gwema ukubeka iingots zetsimbi ezibandayo ngokuthe tye okanye uziphose kwi-crucible phantsi kwayo nayiphi na imeko.Landela ezi zikhokelo zokubiza:
Yomisa ii-ingots zetsimbi kunye neziqwenga ezinkulu ngaphambi kokuba uzifake kwi-crucible.
Beka izinto zetsimbi ngokukhululekileyo kwi-crucible, ngokuqala ngamaqhekeza amancinci njenge-cushion kwaye ungeze iinqununu ezinkulu.
Kuphephe ukongeza i-ingots ezinkulu zesinyithi kwisixa esincinci sesinyithi esingamanzi, njengoko kunokubangela ukupholisa okukhawulezileyo, okukhokelela ekuqinisweni kwesinyithi kunye nokuqhekeka okunokwenzeka kokuqhekeka.
Coca i-crucible yazo zonke isinyithi zamanzi ngaphambi kokuvala okanye ngexesha lokuphumla okwandisiweyo, njengoko i-coefficients yokwandiswa eyahlukileyo ye-crucible kunye nesinyithi inokukhokelela ekuqhekekeni ngexesha lokufudumala.
Gcina inqanaba lentsimbi etyhidiweyo kwi-crucible ubuncinane ubuncinane be-4 cm ngaphantsi phezulu ukukhusela ukuphuphuma.
Ukususwa kweSlag:
Yongeza i-slag-removing agents ngqo kwintsimbi etyhidiweyo kwaye ugweme ukuzisa kwi-crucible engenanto okanye ukuxuba kunye nentlawulo yetsimbi.
Gxuma isinyithi esityhidiweyo ukuze kuqinisekiswe ngokusasazwa kwe-slag-removing agents kunye nokuthintela ukuba bangaphenduli ngeendonga ezinqamlekileyo, njengoko oku kunokubangela ukubola kunye nomonakalo.
Coca iindonga zangaphakathi ze-crucible ekupheleni kosuku ngalunye lomsebenzi.
ULondolozo lwasemva kokusetyenziswa kweCrucible:
Khulula isinyithi esinyibilikisiweyo kwi-crucible phambi kokuvala iziko.
Ngelixa isithando somlilo sisatshisa, sebenzisa izixhobo ezifanelekileyo zokukrazula nayiphi na i-slag ebambelele kwiindonga ezinqamlekileyo, uqaphele ukuba ungonakalisi i-crucible.
Gcina imingxuma yokuvuza ivaliwe kwaye icocekile.
Vumela i-crucible ukuba iphole ngokwemvelo kwiqondo lokushisa.
Kwii-crucibles ezisetyenzisiweyo ngamaxesha, zigcine kwindawo eyomileyo kwaye ekhuselweyo apho kungenakwenzeka ukuba ziphazamiseke.
Phatha ii-crucibles ngobunono ukuze ugweme ukuphuka.
Gwema ukuveza i-crucible emoyeni ngokukhawuleza emva kokufudumeza, njengoko oku kunokubangela
