Indlela ekhuselekileyo yokusetyenziswa kwesixhobo sokuvuza esivuzayo se-crucible isithanthi somlilo esincibilikiweyo

Isixhobo se-alamu sokuvuza kwe-crucible yesithando sokunyibilikisa isinyithi siyimfuneko ukuze kuqinisekiswe ukuveliswa okukhuselekileyo, ukuthintela ukwenzeka kunye nokwandiswa kweengozi zokuvuza kwesithando somlilo, ukuncedisa ukugweba ukusetyenziswa kwesithando somlilo, kunye nokwandisa ixesha lesithando somlilo. Kuyimfuneko ukuseta inkqubo ye-alarm yokuvuza kwe-crucible. Ngokuqhelekileyo, isixhobo esithe ngqo se-alamu sisetyenziselwa ukufakela i-electrode yensimbi engenasici (i-electrode yokuqala) ekudibaneni nentsimbi etyhidiweyo kunye neplate yensimbi engenasici (i-mesh) ye-electrode yecala (i-electrode yesibini) phakathi kwe-coil induction of the furnace lining. Xhuma i-electrode ikhokelela kwisixhobo se-alamu. Xa isinyithi esityhidiweyo sivuza kwi-electrode yecala, i-current iphakama kwixabiso elimiselweyo, kwaye isixhobo se-alarm siyasebenza. Ngethuba lokufakwa kwesixhobo se-alamu, kuyimfuneko ukujonga ukuba uxhulumaniso phakathi kocingo olukhokelayo kunye ne-electrode lulungile; nokuba ucingo lwelothe lusekelwe phantsi (ukumelana nomhlaba> 5kC). Ngethuba lokusebenza, ngamanye amaxesha ucingo lwensimbi engenasici luyancibilika phantsi kwesithando somlilo. Unokufaka intonga ye-conductive kwintsimbi etyhidiweyo kwaye usebenzise i-multimeter ukuyilinganisa. Ukuba i-stainless steel wire inqanyuliwe kwi-lining ye-furnace, i-alarm system iya kuphumelela kwaye inokubekwa kuphela xa isithando somlilo sakhiwe kwakhona kwixesha elizayo. Emva kokuba i-alamu yenzekile, khangela ukuba i-alam yobuxoki (i-alamu yobuxoki ibandakanya ikakhulu: ukuphazamiseka okunokubakho okubangelwayo, ukubethelwa kwe-wire lead, kunye ne-furnace lining emanzi). Ukuba i-alamu yobuxoki iyapheliswa, i-furnace lining inokumiselwa ukuba yonakaliswe.

Uluhlu olutsha lwesithando somlilo sesinyithi sikwinqanaba lokuqala lokunyibilika kwe-oven ye-lining. Ngenxa ye-adsorption yamanzi kunye nemvula ye-boric acid crystal yamanzi ebusweni bomgca, ukuchasana kwe-lining kunciphisa, kwaye ukufundwa kwe-ammeter ye-alarm kuphakama. Xa iphezulu, ixabiso le-alarm linokufikelelwa, kodwa ngoku ngokubanzi likhuphuka ngokuthe ngcembe ngeli xesha. Emva kokuba ii-furnaces ezimbalwa ziyancibilika, ziya kuncipha ngokuthe ngcembe kwaye zibuyele kuluhlu oluqhelekileyo, olunokuthi luhluke kwi-alamu yokuvuza ngokubanzi. Ngamanye amaxesha i-alarm current, ebisoloko ihla ngexesha lokumisa, iqalise ukunyuka kwakhona. Ngeli xesha, isithando somlilo sahlolwa kwaye kwafunyaniswa ukuba ngenxa yokusebenza ngokungakhathali, i-scaffolding yentsimbi eyongeziweyo yabangela ukuba ubushushu obuphantsi obunyibilikayo bentsimbi bunyuke ngokukhawuleza kwaye budlule ubushushu be-sintering. (Ngaphezu kwe-1600 ° C), yonke i-furnace lining ifakwe i-sintered phantse kuphela i-vitrified enzima kunye ne-hard sintered layer, ngaphandle kwe-transition layer kunye ne-loose layer, ngaloo ndlela ibangela ingozi yokuvuza kwesithando somlilo. Ngeli xesha, i-alamu yokuvuza kwesithando somlilo ngexesha le-oven ichanekile. I-3t intermediate intermediate smelting furnace isebenzisa esinye isixhobo se-alam, esinye ngesinye isixhobo sokubona ukuvuza. Isixhobo sibandakanya imodyuli yokufumanisa umhlaba oxhunywe kumandla ombane kunye neprobe yokuvuza komhlaba efumaneka kwisithando somlilo. Ukuba i-alloy liquid idibanisa i-coil, i-probe yokuvuza komhlaba iya kukhokelela i-coil yangoku emhlabeni, kwaye imodyuli ye-grounding probe iya kuyibona kwaye iyinqumle. Ukunikezelwa kwamandla ukumisa ukuphuka kwe-arc yekhoyili kunye nokuthintela ulwelo lwe-alloy ekuthwaleni i-voltage ephezulu. Isixhobo esibanjwa ngesandla sokuvavanya ukuvuza okuvuzayo sinokusetyenziswa rhoqo kwaye rhoqo ukujonga ukuba inkqubo yokuvuza komhlaba yesithando somlilo ikhuselekile kwaye ithembekile ukuqinisekisa ukuba iprobe yokuvuza komhlaba isekelwe ngokupheleleyo, ukuze ukhuseleko lomsebenzisi kunye iziko liqinisekisiwe.
