Kubavelisi bentsimbi engagqwaliyo kunye nentsimbi ecocekileyo kakhulu, ukuzinza kwesithando se-VOD kumisela ngokuthe ngqo ukusebenza kakuhle kwemveliso, iindleko zexesha lokungasebenzi, kunye nomgangatho wokugqibela wentsimbi. Ukusebenzisa isithando se-VOD kuthetha ukulwa neemeko zokusebenza ezigqithisileyo: i-vacuum ephezulu, ukujikeleza rhoqo kobushushu, ukukhuhla intsimbi enyibilikisiweyo kakhulu, kunye nokugqwala kwe-alkaline slag enamandla. Iingxaki ezininzi zobomi obufutshane azibangelwa ziimpazamo zokusebenza, kodwa kukukhethwa kwezitena ezichaseneyo kwiindawo ezahlukeneyo zesithando.
Inkqubo epheleleyo ye-VOD furniture lining ifuna izixhobo zokuchasana ezilinganisiweyo kwiileya ezahlukeneyo ezisebenzayo. Nazi iintlobo ezintlanu zezitena zokuchasana ezingundoqo ekufuneka zizazi zonke iqela leengcali ze-metallurgical:
Izitena zeMagnesia-Chrome(I-Core Working Lining)
Njengezona zinto zisetyenziswa kakhulu, izitena ze-magnesia-chrome zisebenza eludongeni lwesithando somlilo, ichibi elinyibilikisiweyo kunye nomgca we-slag - ezona ndawo zinzima zokugqwala. Ngenxa yokumelana okuhle kwe-slag, ukusebenza okuchasene nokungena kunye nolwakhiwo oluzinzileyo lobushushu obuphezulu, ziyamelana ngempumelelo nokuxobuka kunye nokuncitshiswa phantsi kweemeko zobushushu obuphezulu ze-vacuum ixesha elide. Lolona khetho lusebenzayo kwaye lunokuthenjwa kakhulu kwimveliso yesithando somlilo esiqhelekileyo se-VOD.
Izitena zeMagnesia-Calcium(Isisombululo sokwenza intsimbi esikumgangatho ophezulu)
Kwiifektri ezigxile kwintsimbi engagqwaliyo ekumgangatho ophezulu kunye nentsimbi ecocekileyo kakhulu, izitena ze-magnesia-calcium zezona zinto zifanelekileyo zokufakelwa ulwelo. Zine-alkaline slag egqwesileyo kunye nokusebenza okungena-chromium, ziyahambelana nemigangatho yokusingqongileyo kwaye ziphepha ukungcola kwentsimbi. Ulwakhiwo lwazo oluxineneyo lumelana nokukhuhla intsimbi enyibilikisiweyo ngamandla kwaye lunciphisa ukufakwa kwayo, nto leyo ephucula kakhulu ubunyulu kunye nomgangatho wentsimbi egqityiweyo.
Izitena zeMagnesia ezinamandla aphezulu(I-Lining esezantsi kunye ne-Backup)
Isiseko sesithando somlilo kunye nomaleko wotshintsho zifuna amandla aqinileyo okuthwala umthwalo kunye nomthamo wokuthintela uxinzelelo. Izitena ze-magnesia ezinamandla aphezulu zinika ukuchasana okuphezulu, ukumelana okugqwesileyo koxinzelelo kunye nokusebenza okuzinzileyo kobushushu. Zixhasa isakhiwo se-lining esingaphezulu sokusebenza, zinciphisa uxinzelelo lobushushu, kwaye zithintela ukuqhekeka kwe-lining kunye nemingcipheko yokuwa ngokubanzi ngexesha lemveliso yexesha elide.
Izitena zokuvala ezikhaphukhaphu(Umaleko woKhuseleko lwangaphandle)
Ukufakwa kobushushu kubalulekile ekongeni amandla nasekukhuseleni umzimba wesithando somlilo. Izitena zokufakwa kobushushu ezikhaphukhaphu zisetyenziswa kumaleko wesithando somlilo sangaphandle, zinomoya ophantsi wokuqhuba ubushushu kunye nokugcina ubushushu okugqwesileyo. Zinciphisa ukulahleka kobushushu bangaphakathi, zizinzise ibhalansi yobushushu besithando somlilo, zinciphise ukusetyenziswa kwamandla, kwaye zikhusela isakhelo sentsimbi sangaphandle ekuguqukeni kobushushu obuphezulu.
Izitena ze-Alumina eziphezulu(Iindawo eziNcedisayo neziKhethekileyo)
Izitena ze-alumina ephezulu zizinto ezibalulekileyo ezincedisayo kwiinkqubo ze-VOD. Zifanelekile kwiikhava ze-furnace, iipayipi ze-vacuum kunye neendawo zokutshintsha ezingaphantsi komhlwa, zibonelela ngokumelana okuhle kakhulu nobushushu kunye nokumelana nokukhuhla igesi yeflue. Zihambelana ngokugqibeleleyo nee-linings eziphambili ezisekelwe kwi-magnesia, zenza isakhiwo sonke se-furnace sizinze ngakumbi kwaye sihlale ixesha elide.
Ukudibanisa isitena esifanelekileyo nendawo efanelekileyo ngundoqo wokwandisa ubomi bephulo le-VOD furnace kunye nokunciphisa iindleko zokulungisa ezingacwangciswanga.
Sinikezela ngezitena ezipheleleyo ze-VOD ezichaseneyo nezenzelwe wena kunye nezisombululo zoyilo lwe-lining enye kumashishini ehlabathi asebenzisa isinyithi. Ukuba ufuna izixhobo ezichaseneyo ezisemgangathweni ozinzileyo, ezihlala ixesha elide ukuze uphucule ukusebenza kwesitovu sakho, zive ukhululekile ukunxibelelana nathi ukuze ufumane iingcebiso zobugcisa zobungcali.
