Inkinga ye-Sintering ye ramming impahla yesithando somlilo esiphakathi

Ikhwalithi ye-ramming material yesithando somlilo esiphakathi sinomthelela oqondile ekusebenzeni kahle kokuncibilika. Udonga oluhle lwesithando somlilo lungancibilika izikhathi ezingama-600. Okubi kakhulu ukushisa okungaphezu kuka-100, futhi ngisho nenqwaba yokushisa kufanele ihlanganiswe kabusha. Ukufingqa njalo kolayini lwesithando somlilo akuthinti nje kuphela ukusebenza kahle kokukhiqiza, kodwa futhi kumosha imali ngokubopha inkokhiso. Okulandelayo kuyindlela efanele yokubopha kusuka kumkhiqizi wezinto zokubopha ezomile. …

1. Indima yenzwa yokushisa

Emsebenzini we-sintering, ukulawula izinga lokushisa jikelele kubaluleke kakhulu. Ukuze siqonde ngokucacile izinga lokushisa esithandweni somlilo, sizoxhuma amaphuzu okulinganisa okushisa angu-2-3 phansi naphakathi nendawo kusengaphambili, futhi senze inqubo yethu yokushisa ngokusho kwezinga lokushisa elitholiwe.

2. Ukwengezwa kweqoqo lokuqala lokukhokhiswa kolwelwesi odongeni lwesithando somlilo wokucwilisa

Ngeqoqo lokuqala lokukhokhiswa ngaphambi kwenqubo yokucwilisa, kufanele sibeke kuqala ukwakheka kwamakhemikhali ezinto zayo, ngoba impahla eyinhloko yodonga lwesithando somlilo we-quartz yi-silicon oxide, futhi kusukela ekuhlaziyweni kwe-thermodynamics, i-C ne-Si i-A. isilinganiso sebhalansi siyadingeka ezingeni lokushisa elithile. Lapho izinga lokushisa lensimbi encibilikisiwe liphakeme futhi okuqukethwe kwe-C nakho kuphezulu, okuqukethwe kwe-Si yensimbi encibilikisiwe kudinga ukuba kukhulu, ngoba sidinga ama-degree angu-1580-1600 ngesikhathi senqubo yokucwilisa yodonga lwesithando somlilo Ngesikhathi sokubamba isikhathi, uma insimbi encibilikisiwe inokuqukethwe okuphezulu kwe-C futhi okuqukethwe kwe-Si kungafinyeleli esilinganisweni esidingekayo sebhalansi, insimbi encibilikisiwe izosheshisa ukukhishwa kwe-silicon odongeni lwesithando somlilo ukuze ibhalansise lesi silinganiso, okuholela ekufakweni kodonga lwesithando somlilo Ukuguguleka ngaphambi kwesikhathi kanye nokuncipha kwethonya. impilo yayo yesevisi. Futhi, uma okuqukethwe ku-C no-Si eqeqebeni lethu lokuqala lezinto ezisetshenziswayo ku-ramming kuphansi, izinga lokushisa eliphakeme lizobangela ukwanda kwenani le-iron oxide ne-manganese oxide, futhi lawa ma-oxide azosebenzisana nodonga lwethu lwesithando somlilo. I-silicon dioxide engaphezulu isabela ukuze yakhe i-iron silicate ne-manganese silicate, futhi amaphuzu ancibilikayo alezi zinto ezimbili angaphansi kuka-1350 ℃, futhi yenza ulayini lwethu lwesithando somlilo lube mncane ngaphambi kwesikhathi futhi lunciphise impilo yesevisi. …

Uma kucatshangelwa amaphuzu amabili angenhla, elinye elokucabangela ukuminyana kwezinto ezinqunyiwe ezingeziwe. Yonke inqubo yokuncibilika kwesithando sethu sikagesi iwukuthi amandla kagesi aguqulwa abe amandla kazibuthe ngokusebenzisa ikhoyili, bese indawo kazibuthe isabela neshaje yensimbi ukuze iguqule ibe amandla kagesi, bese isuka emandleni kagesi iye emandleni kagesi. Ukuguqulwa kwamandla okushisa, ngoba i-crucible iyinsimbi ye-mold crucible lapho isithando somlilo sihhavini, uma indawo yokudla ngaphakathi kwesithando somlilo ikhululekile, ingxenye ye-crucible izosabela ngokweqile ku-magnetic field, okwenza ukushisa kusheshe kakhulu, okubangela ukuguquguquka nokuvuvukala ngaphakathi (ingxenye iphinde ithinteke ubukhulu besikhunta se-crucible. Ngalesi sikhathi, uhlaka lwesihlabathi se-quartz odongeni lwesithando somlilo alukakagxili futhi luqiniswe, futhi izinto eziphikisayo zizogcwalisa isikhala esikhubazekile somlilo. isikhunta, okuholela ekwehleni kokuminyana kwezinto ezifakwa odongeni lwesithando somlilo futhi kuthinte impilo yayo yenkonzo.
