Imishini eyinhloko yokuncibilikisa insimbi engeyona ayoni iziko zokuncibilikisa insimbi ezingenayo ayoni. Ukutadisha isidingo sezinhlobonhlobo kanye nekhwalithi yezinto eziphikisayo ngenxa yentuthuko yezobuchwepheshe yemboni yokuncibilikisa insimbi engeyona ayoni kufanele kube umsebenzi oyinhloko wemboni ye-refractory ukwandisa ukuphila kwezithando zokuncibilikisa zensimbi ezingenayo ayoni futhi andise ukukhiqizwa.
1. Imboni yokuncibilikisa ithusi
Inqubo yokukhiqiza ithusi iyona enezindlela eziningi ezinsimbi ezihlukahlukene ezingezona ayoni. Inqubo yokukhiqiza yethusi ezweni lami ayihlanganisi nje kuphela zonke izinqubo zethusi emhlabeni, kodwa futhi ihlanganisa izinqubo eziyingqayizivele ezweni lakithi, njengendlela yethusi yokuncibilikisa isiliva kanye ne-oxygen phansi. Vuthela isithando somlilo esincibilikayo.
Enqubweni yokuncibilikisa ithusi lomlilo, umehluko ikakhulukazi ekukhiqizeni i-matte yethusi, kuyilapho ukuvuthwa kwesiguquli nokucwengisiswa kwethusi kufana ngokuyisisekelo.
Ngenxa yezinga lokushisa eliphezulu kumbhoshongo wokusabela wesithando somlilo, ukugeleza komoya okunesivinini esikhulu okuxutshwe nokuncibilika kuguguleka futhi kugqwalise umbhoshongo wokusabela. Njengamanje, kusetshenziswa izitini ze-magnesia-chrome ezihlanganisiwe. Ngasikhathi sinye, ukuze kuvikelwe izitini ze-magnesia-chrome ezihlanganisiwe, izingqimba ezimbalwa zamabhantshi amanzi epuleti yethusi avundlile ahlanganiswe endaweni yokwakhiwa kwezitini, futhi amapayipi ethusi apholile amanzi noma amabhantshi amanzi epuleti lethusi aqondile ahlelwa phakathi kokwakhiwa kwezitini kanye igobolondo. , phezulu kombhoshongo wokusabela kanye nendawo yokushisa ephansi ephezulu yakhiwe ngezitini ezijwayelekile ze-magnesia-chrome. Engxenyeni yokuxhumana phakathi kombhoshongo wokusabela kanye nangaphezulu kwethangi le-sedimentation (ngokufanayo ukuxhumana phakathi kwethangi le-sedimentation kanye nomsele okhuphukayo), ingaphansi kokuguguleka nokugqwala okunamandla kokuncibilika kwezinga lokushisa eliphezulu kanye nezinga lokushisa eliphezulu eligcwele uthuli. ukugeleza komoya, futhi ulwelwesi lonakala kalula, ngakho-ke ithusi elicijile ngokuvamile lisetshenziswa. Isakhiwo sezitini ezisezingeni eliphezulu ze-magnesia-chrome ezishunyekwe ngamapayipi agxiviza ama-refractory castables noma amabhantshi amanzi ethusi.

2. Imboni yomthofu ne-zinc
I-lead-zinc airtight furnace
I-lead-zinc airtight blast furnace iyisithando somlilo esikhethekile esincibilikisa izinsimbi ezimbili zomthofu kanye ne-zinc ngesikhathi esisodwa kudivayisi eyodwa. Izici zayo ukuthi umoya oshisayo ongu-800-850 ℃ usetshenziselwa ukuqhuma; phezulu kwesithando somlilo kugcinwa ekushiseni okuphezulu kwe-1050-1100 ℃; Iziko le-lead-zinc airtight blast furnace lakhiwe ngezitini ze-magnesia, iziko liyibhantshi lamanzi, umzimba wesithando somlilo wakhiwe ngezitini eziphezulu ze-alumina, futhi phezulu kwesithando somlilo kufakwe amafindo ngezinto eziphikisayo ze-alumina ezingenakulinganiswa. Imibhede yangaphambili yeziqhumiso eziqhumayo ezingangeni moya i-lead-zinc yonke iyimibhede engaphambili yokushisisa ngogesi, futhi impilo yabo yesevisi iphansi kunaleyo yeziqhumiso eziqhumayo. Ikakhulukazi ngenxa yokuguguleka kwe-slag nokukhuhla imigqa ye-slag. Njengamanje, amaziko amabili okuqhunyiswa kwe-lead-zinc e-China afakwe izitini ze-chrome slag nezitini ze-aluminium-chromium-titanium ngokulandelana. Nakuba iminyaka yesithando somlilo ingafinyelela ngaphezu konyaka ongu-1, isephansi kunempilo yeziqhumiso eziqhumayo ezingangeni moya eziholayo. Indlela yokuqhubeka nokuthuthukisa impilo yesithando sombhede ongaphambili wokushisa kagesi ukuze uhambisane nempilo yesithando somlilo somlilo we-lead-zinc kuyisihluthulelo sokuthuthukisa izinga lokusebenza kwesithando somlilo somlilo we-lead-zinc.
