Xa ufakaiminqamlezo, kungcono silandele iindlela ezichanekileyo zokuqinisekisa ukhuseleko nosetyenziso olusebenzayo.Nanga amanye amacebiso:
Indlela engalunganga: Kuphephe ukushiya indawo encinci phakathi kwezitena ezixhasayo kunye nei-crucible.Indawo engonelanga inokuthintela ukwandiswa kwei-cruciblengexesha lokufudumala, okukhokelela ekuqhekekeni kunye nokusilela okunokwenzeka.
Indlela ecetyiswayo: Faka amaqhekeza amancinci amaplanga phakathi kwe-crucible kunye nezitena ezixhasayo.Ezi ziqwenga zokhuni ziya kutshisa ngexesha lokufudumeza, ukudala indawo eyaneleyo yokwandisa.
Izilumkiso ngexesha lofakelo:
Ngaphambi kokufaka i-crucible, jonga indawo yangaphakathi yesithando somlilo.Iindonga zesithando somlilo kunye nomgangatho kufuneka zihambelane ngaphandle kwesinyithi okanye intsalela ye-slag.Ukuba kukho i-samente okanye i-slag ebambelele kwiindonga okanye umgangatho, kufuneka icocwe.Ngaphandle koko, ukuqhubela phambili kwedangatye kunokuthintela, kubangele ukufudumala kwendawo, i-oxidation, okanye imingxuma emincinci kwiindonga ezinqamlekileyo.
Ukuxhasa isiseko se-crucible:
Xa ufaka i-crucible, sebenzisa isiseko se-cylindrical esikhulu ngokwaneleyo esilingana nesiseko se-crucible.Isiseko kufuneka sibe sikhulu kancinci nge-2-3 cm, kwaye ukuphakama kwayo kufuneka kudlule umngxuma wempompo ukuthintela ukuvezwa ngokuthe ngqo kwesiseko se-crucible kwidangatye.Oku kunceda ukuthintela ukukhukuliseka okukhawulezayo kwezinto ezisisiseko, ezinokukhokelela ekubeni i-crucible ibe yi-conical okanye i-crack ngenxa yoxinzelelo olungalinganiyo kwisiseko.
Ukuthintela ukunamathela phakathi kwe-crucible kunye nesiseko, faka umaleko we-insulation material (njengesanti enqabileyo okanye ikhadibhodi) phakathi kwabo.
Xa usebenzisa i-furnace ethambekileyo enesiseko sohlobo lwe-falcon, qinisekisa ukuba i-protrusions kwisiseko ihambelana ne-grooves ye-crucible.Ukuba iiprotrusions ziphezulu kakhulu okanye zikhulu, zingenza uxinzelelo olugqithiseleyo kwisiseko se-crucible, ekhokelela ekuqhekekeni.Ukongezelela, emva kokuthotywa, i-crucible ayinakulungiswa ngokukhuselekileyo.
Kwii-crucibles ezinama-spouts okugalela ixesha elide, kubalulekile ukubonelela ngesiseko esaneleyo kunye nokukhusela inkxaso ye-crucible.Ukuxhaswa kwesiseko esingafanelekanga kunokubangela ukuba "ukuxhoma" kwe-crucible kuphela nge-spout ngaphakathi kwesithando somlilo, okukhokelela ekuqhekekeni ukusuka kwindawo ephezulu.
Usulelo phakathi kwe-crucible kunye nezitena ezixhasayo:
I-gap phakathi kwe-crucible kunye nezitena ezixhasayo kufuneka zibe zanele ukulungiselela ukwandiswa kwe-crucible ngexesha lokufudumala.Ukubeka izinto ezinokutsha (ezifana neengcezu zokhuni okanye ikhadibhodi) ngokuthe ngqo phakathi kwe-crucible kunye nezitena ezixhasayo eziphezulu kunokudala indawo efunekayo.Ezi zinto ezitshayo ziya kutshisa ngexesha lokufudumeza kwe-crucible, ukushiya ngasemva imvume eyaneleyo.
Kwiziko apho i-gesi yokukhupha ikhutshwa kwicala, ukutywina isithuba phakathi kwe-crucible kunye nodonga lwesithando somlilo kunye noboya be-insulation kunye nokuwulungisa nge-samente yokumelana nokushisa okuphezulu kuyacetyiswa.Oku kuthintela i-oxidation kunye nokuqhekeka komphezulu we-crucible ngenxa yokutywinwa okungafanelekanga kuphahla lwesithando somlilo.Ikwakhusela izinto zokufudumala ngexesha lokwandiswa okuphezulu kwe-crucible.
(Qaphela: Kucetyiswa ukuba kusetyenziswe ikhava ye-crucible ukukhusela i-oxidation, ukuqhekeka okuphezulu, kunye nokubola. Umgca wangaphakathi wesigqubuthelo se-crucible kufuneka ugubungele indawo yangaphakathi ye-crucible ukuya kwi-100mm ukubonelela ngokhuseleko olungcono kwiimpembelelo zangaphandle kunye ne-oxidation.)
Kwiindawo zokushisa, ngaphantsi kwe-spout yokuthululela kunye nesiqingatha sokuphakama kwe-crucible, faka enye okanye ezimbini izitena ezixhasayo ukuze ukhusele i-crucible.Faka ikhadibhodi phakathi kwe-crucible kunye nezitena ezixhasayo ukugcina indawo eyaneleyo kunye nokuthintela umqobo ngexesha lokwandiswa kwe-crucible.
Ngokulandela ezi zikhokelo kunye nokuthobela iindlela ezifanelekileyo zokufakela, ukusebenza kunye nexesha lokuphila kwee-crucibles kunokwandiswa.Ukuqinisekisa ukufakela okukhuselekileyo nokusebenzayo kwe-crucible
