Izimiso Ezinhlanu Zokwenziwa Kwensimbi Yokungeniswa Okuncibilikisa Isithando Somlilo
Izimiso Ezinhlanu ze I-Induction Melting Furnace Ukwenziwa kwensimbi
Izimiso Ezihlanu Zokulayisha
1. Qonda izindawo ezintathu zokusabalalisa ukushisa ku-crucible
Indawo yokushisa ephezulu: ezungeze izingxenye ezimaphakathi neziphansi ze-crucible, ngenxa yomphumela wesikhumba sikagesi yindawo yokucebisa umugqa wamagnetic, kuyalulekwa ukuthi wengeze ama-alloys aphikisayo kule ndawo bese ufaka imichilo emikhulu ye-cross-section.
Indawo yokushisa engaphansi kophezulu: maphakathi nendawo ephansi ye-crucible.
Indawo yokushisa ephansi: Ingxenye ephezulu ye-crucible ihlakaza ukushisa okukhulu futhi imigqa yensimu kazibuthe ihlakazekile. Uma iphansi le-crucible libekwe ngendlela engafanele, indawo yokushisa ephansi ephansi izoba indawo yokushisa ephansi.
2. Yakha ichibi lensimbi elincibilikisiwe ngokushesha ngangokunokwenzeka, lihlukaniswe libe yizimo ezimbili
Kunezinsimbi eziningi zensimbi ekukhokhisweni nomsebenzi omncane noma awukho umsebenzi. Uma kukhona phansi ngaphezulu kwesithando somlilo, akufanelekile ukwengeza i-lime ukuze uvimbele insimbi kusuka ku-slagging; izinto ezincane nezincane zakha ichibi elincibilikisiwe ngaphambi kokwengeza izinsalela zensimbi; uma singekho isigaxa sensimbi, engeza u-2-4 kg welimu ezansi kwesithando somlilo. Yenza i-slag ibe ne-alkalinity ethile ngesikhathi sokuncibilika, i-2.2-2.8 ihambisana ne-desulfurization kanye nokuqiniswa kwe-phosphorus.
Ngenxa yalesi sizathu, izinto ezincane kufanele ziqoqwe ngokwehlukana. Lapho isithando somlilo sivuliwe, sengezwa ngokushesha endaweni yokushisa engaphansi kwe-crucible ukuze kwakhiwe ichibi elincibilikisiwe ngokushesha ngangokunokwenzeka. Ichibi elincibilikisiwe kuphela elingamunca imigqa yamandla kazibuthe eyengeziwe ukuze kusheshiswe ukuncibilika.
3. I-ferro-tungsten ne-ferro-molybdenum kufanele zifakwe endaweni enezinga eliphezulu lokushisa ngesikhathi esifanele ukuze kuqinisekiswe ukwakheka okufanayo, ukuvimbela isampula yokuhlanganisa engamele nokuhlukaniswa kwezinto eziyigugu ze-alloy kumkhiqizo oqediwe, kodwa akufanele. kube kusesekuseni kakhulu ukuvimbela i-ferro-tungsten ukuthi ingashoni phansi.
4. Izigaxa zika-oyela nezensimbi zifakwa kakhulu emaqoqweni asekuqaleni. Ngemva kokwengeza izinsalela zikawoyela nensimbi, sebenzisa i-Huangshi deoxidizer noma i-aluminium eyinhlanganisela ye-silicomanganese yokufaka ukufaka i-deoxidation yemvula, futhi ingxenye yomkhiqizo iwumkhiqizo we-oxide deoxidation, njengensimbi. I-oksijeni encibilikisiwe iphezulu kakhulu, futhi kwakhiwa ama-oxide amasha oketshezi emazingeni okushisa aphakeme, azotholwa kamuva abe yi-electroslag remelting futhi anciphise ubumsulwa bensimbi. [H] Kunzima ukususa ngesikhathi sokuncibilika kwe-electroslag, futhi kwakhiwa amabala amhlophe nemifantu ku-billet ye-ingot.
5. Lapho ufaka isithando somlilo, qaphela ukuhleleka lapho inkokhiso iwela khona ukuze kuvinjwe ukuvala ibhuloho kanye ne-jamming. Ungasebenzisi udonga lwe-crucible njenge-fulcrum yokuvula indaba, futhi ungashayi ingxenye engenhla ye-crucible ngokumelene nodonga lokunamathela esithandweni somlilo i-nodular oxide slag, ezolimaza i-crucible futhi inciphise impilo ye-crucible. Ingasuswa ngezindlela zamakhemikhali, njengokwengeza i-slag remover odongeni lwesithando somlilo ngesikhathi sokuncibilika.
