Izinhlobo Nezindlela Zokusetshenziswa Kwezinto Eziphikisayo Zeziko Ezincibilikisa Izimboni

The main imishini ezishisayo weisithando somlilo sezimbonikuhlanganisa calcination kanye sintering esithandweni, ithangi electrolytic kanyeisithando somlilo.Ulwelwesi lwendawo yomlilo yeziko elijikelezayo ngokuvamile lwakhiwe ngezitini ezine-alumina ephezulu, futhi izitini zobumba zingasetshenziswa njengolwelwesi kwezinye izingxenye.Ungqimba lwe-refractory fiber oluzwakalayo lubekwe phezu kongqimba lwe-insulation yokushisa eduze kwegobolondo lesithando somlilo, bese kwakhiwa ungqimba lwezitini ezingasindi noma izitini ezingasindi.Ukuthelwa kwekhwalithi okuhlanjululwayo kwe-refractory.

Igobolondo leseli ye-electrolytic lenziwe ngepuleti lensimbi, futhi ungqimba lwebhodi lokufakwa ngaphakathi noma i-fiber refractory lizwakala libekwe ngaphakathi kwegobolondo, bese kwakhiwa izitini ezilula noma kuthelwa izinto ezilula eziphikisayo, bese kwakhiwa izitini zobumba ukuze yakha ungqimba olungasebenzi, futhi iseli ye-electrolytic isebenza Ungqimba lungenziwa kuphela ngezinto eziphikisayo zekhabhoni noma ze-silicon carbide ezine-conductivity kagesi enhle, ukuze zimelane nokungena kwe-aluminium encibilikisiwe nokuguguleka kwe-fluoride electrolyte.Esikhathini esedlule, ungqimba olusebenzayo lodonga lweseli yeseli ye-electrolytic ngokuvamile lwakhiwa ngamabhulokhi ekhabhoni.Eminyakeni yamuva nje, iJapane namanye amazwe aseNtshonalanga Yurophu asebenzise izitini ze-silicon carbide ezihlanganiswe ne-silicon nitride ukuze azakhe, futhi bathola imiphumela emihle.

Isendlalelo esisebenzayo esingaphansi kweseli ye-electrolytic ngokuvamile sakhiwe ngamabhulokhi ekhabhoni anamajoyini amancane futhi agcwaliswe nge-carbon paste ukuvimbela ukungena kwesisombululo se-aluminium futhi kuthuthukise ukusebenza.

I-aluminium esetshenziswa kakhuluimishini yokuncibilikisayisithando somlilo esibuyisela emuva.Uhlaka lwesithando somlilo oluthintana nesisombululo se-aluminium ngokuvamile lwakhiwe ngezitini eziphezulu ze-alumina ezinokuqukethwe kwe-A1203 okungu-80% -85%.Lapho kuncibilika i-aluminium yensimbi ehlanzekile, kufanele kusetshenziswe izitini ze-mullite noma izitini ze-corundum.Kwamanye amafekthri, izitini ze-silicon carbide ezihlanganiswe ne-silicon nitride zisetshenziselwa ukwakha ezingxenyeni ezijwayele ukuguguleka nokuguga, njengomthambeka weziko nezinto ezilahlwayo ze-aluminium.Izitini ezizibophezele noma ze-silicon nitride-bonded silicon carbide nazo zisetshenziswa njengama-linings anezitini ze-zircon.Ukuze kuvinjwe indawo yokukhipha i-aluminium, umphumela we-vacuum casting refractory fiber ungcono.Izindwangu zesithando somlilo ezingaxhumani nesisombululo se-aluminium ngokuvamile zakhiwe ngezitini zobumba, izinsimbi eziphikisayo zobumba noma amapulasitiki aphikisayo.Ukuze kusheshiswe isivinini sokuncibilika futhi wonge amandla, izitini ezingasindi, izinsimbi ezingasindi eziphikisayo kanye nemikhiqizo ye-fiber refractory ngokuvamile isetshenziswa njengezendlalelo zokuvikela ukushisa.

Isithando somlilo esincibilikisa i-aluminium esincibilikisayo siphinde sisetshenziswe ngokujwayelekile.Ulayini ngokuvamile lwenziwa nge-high-alumina refractory castable noma i-refractory ramming material enokuqukethwe kwe-A1203 engu-70% -80%, futhi ukhonkolo ophikisayo we-corundum nawo usetshenziswa njengolayini.

I-aluminium encibilikisiwe igeleza iphuma endaweni yokukhipha i-aluminium yesithando somlilo ngethangi lokugeleza kwe-aluminium.Uhlaka lwethangi ngokuvamile lwenziwa ngezitini ze-silicon carbide, futhi kukhona namabhulokhi enziwe ngaphambili esihlabathi se-silica esihlanganisiwe.Uma ibhulokhi eyakhiwe ngaphambilini isetshenziswa njengohlaka lwethangi, indawo engaphezulu kufanele imbozwe ngesihlabathi se-silica esihlanganisiwe noma Sebenzisa usimende ophezulu we-alumina ohlanganisiwe we-silica sand refractory castable njengongqimba oluvikelayo.
