Indlela ephephile yokusebenzisa i-alamu yokuvuza kwe-crucible yesithando somlilo esincibilikisa insimbi
Indlela ephephile yokusebenzisa idivayisi ye-alamu yokuvuza ye-crucible insimbi ichitha isithando somlilo
Idivayisi ye-alamu yokuvuza ye-crucible yesithando somlilo esincibilikisa insimbi iyadingeka ukuze kuqinisekiswe ukukhiqizwa okuphephile, ukuvimbela ukwenzeka nokwanda kwezingozi zokuvuza kwesithando somlilo, ukusiza ukwahlulela ukusetshenziswa kolayini lwesithando somlilo, nokwandisa iminyaka yesithando somlilo. Kuyadingeka ukusetha i-alamu yokuvuza kwe-crucible. Ngokuvamile, idivayisi ye-alamu yamanje eqondile isetshenziselwa ukufaka i-electrode engaphansi yensimbi engagqwali (i-electrode yokuqala) lapho ithinta insimbi encibilikisiwe kanye nepuleti lensimbi engagqwali (i-mesh) i-electrode eseceleni (i-electrode yesibili) phakathi kwekhoyili yokungeniswa yolayini lwesithando somlilo. Xhuma i-electrode eholela kudivayisi ye-alamu. Lapho insimbi encibilikisiwe ivuza ku-electrode eseceleni, okwamanje kukhuphukela enanini elimisiwe, futhi idivayisi ye-alamu iyasebenza. Ngesikhathi sokufakwa kwedivayisi ye-alamu, kuyadingeka ukuhlola ukuthi ukuxhumana phakathi kocingo oluholayo kanye ne-electrode kuhle; ukuthi intambo yomthofu iphansi (ukumelana nomhlaba> 5kC). Ngesikhathi sokusebenza, ngezinye izikhathi ucingo lwensimbi engagqwali luyancibilika ngaphansi kwesithando somlilo. Ungakwazi ukufaka i-conductive rod ensimbi encibilikisiwe futhi usebenzise i-multimeter ukuyikala. Uma intambo yensimbi engagqwali inqanyulwa olayini besithando somlilo, isistimu ye-alamu izohluleka futhi ingabekwa kuphela lapho isithando somlilo sakhiwe kabusha ngokuzayo. Ngemva kokuba i-alamu ingenile, hlola ukuthi ingabe i-alamu engamanga (ama-alamu amanga ikakhulukazi ahlanganisa: ukuphazamiseka okungenzeka okubangelwe, izintambo zomthofu eziphansi, kanye nolayini lwesithando somlilo olumanzi). Uma i-alamu yamanga isusiwe, ulayini lwesithando somlilo lunganqunywa ukuthi lonakalisiwe.
Ulwelwesi olusha lwesithando somlilo esincibilikisa insimbi lusesigabeni sokuqala sokuncibilika kwehhavini yolwelwesi. Ngenxa yokukhangisa kwamanzi kanye nemvula yamanzi ekristalu ye-boric acid ebusweni bolwelwesi, ukumelana kolwelwesi kuncipha, futhi ukufundwa kwe-ammeter ye-alamu kuyenyuka. Uma iphezulu, inani le-alamu lingafinyelelwa, kodwa okwamanje ngokuvamile likhuphuka kancane kancane ngalesi sikhathi. Ngemuva kokuthi izithando zomlilo ezimbalwa zincibilike, zizokwehla kancane kancane futhi zibuyele ebangeni elijwayelekile, elingahlukaniswa ne-alamu yokuvuza evamile. Ngezinye izikhathi i-alamu, ebilokhu yehla phakathi nenkathi yokomisa, isiqale ukuphakama futhi. Ngalesi sikhathi, isithando somlilo sahlolisiswa futhi kwatholakala ukuthi ngenxa yokusebenza ngokunganaki, i-scaffolding yensimbi eyengeziwe yabangela izinga lokushisa eliphansi lokuncibilika kwensimbi encibilikisiwe likhuphuke kakhulu futhi lidlule izinga lokushisa le-sintering. (Ngaphezu kuka-1600°C), lonke ulayini lwesithando somlilo lufakwe emanzini cishe kuphela ungqimba oluqinile oluqinile futhi oluqinile, olungenayo isendlalelo esishintshayo kanye nongqimba oluxekethile, ngaleyo ndlela kubangele ingozi yokuvuza kwesithando somlilo. Ngalesi sikhathi, i-alamu yokuvuza kwesithando somlilo phakathi nohhavini ilungile. Isithando somlilo se-3t esimaphakathi esincibilikisa sisebenzisa enye idivayisi ye-alamu, idivayisi eyodwa yokutholwa kokuvuza. Idivayisi ihlanganisa imojuli yokuthola indawo ephansi exhunywe kugesi kanye nophenyo lokuvuza okuphansi olutholakala esithandweni somlilo. Uma i-alloy liquid ithinta ikhoyili, i-grounding probe yokuvuza izoholela i-coil current phansi, bese i-grounding probe module izoyibona bese iyinqamula. Ukunikezwa kwamandla okumisa ukuqhekeka kwe-arc yekhoyili nokuvimbela uketshezi lwe-alloy ukuba luthwale i-voltage ephezulu. Ithuluzi lokuhlola ukuvuza okubanjwe ngesandla elingaphansi lingasetshenziswa njalo futhi njalo ukuhlola ukuthi uhlelo lokuvuza okuvuza phansi kwesithando somlilo luqinile futhi luthembekile ukuze kuqinisekiswe ukuthi uphenyo lokuvuza komhlaba lusekelwe ngokuphelele, ukuze ukuphepha komsebenzisi kanye isithando somlilo siqinisekisiwe.
