Isicwangciso soqwalaselo lwezitena eziqhankqalazayo kunye nezinto eziphoswayo kwiziko leNoranda

I-Noranda furnace lining isebenzisa izitena ze-alkaline refractory, zidibaniswe ngokuthe ngqo nezitena ze-magnesia-chrome, ezinozinzo oluphezulu lobushushu obuphezulu, i-porosity ephantsi ebonakalayo, ukunyanzeliswa komoya ophantsi, ukuchasana kakuhle kwe-thermal kunye nokumelana nokukhukuliseka kwe-slag; I-electrofusion edityaniswe ne-magnesium Chrome izitena zineekhemikhali eziphezulu zokucoceka, umxholo wokungcola ophantsi, ubuninzi obuninzi, amandla okushisa aphezulu okushisa, ukuxhathisa okulungileyo kwe-slag kunye nokushisa okuphezulu kwegesi ye-flue; ngelixa izitena ezidityanisiweyo ze-chrome ze-magnesia zibiza kakhulu, kodwa ziyamelana nobushushu obuphezulu kunye nokunyibilika Ukonakala kunye nokumelana nokhukuliseko kulungile. Ngokuqhelekileyo zisetyenziswa kwiindawo eziphambili kunye nezinyibilikayo ngokulula zomzimba wesithando somlilo. Itheyibhile ye-1 ibonisa izibonakaliso eziphambili zangoku zezitena ze-magnesia-chrome kwii-furnaces zaseNoranda.

Okoko iNoranda yeziko lenkampani ethile yakhiwayo yaza yafakwa kwimveliso, iindawo ezonakalisiweyo zomjikelo wemveliso yokunyibilikisa ziye zahlolwa, zahlalutywa kwaye zaphandwa. Kwiminyaka edlulileyo yokulungiswa ngokutsha, ukucwangciswa okuphuculweyo kwezixhobo ezichasayo kwinxalenye nganye yomgca kwamiselwa kwakhona. Kwindawo yedamper ebalulekileyo kunye nesengozini, izibuko lokutshaja kwisiqingatha sodonga lokuphela kokutshaja, umngxuma wokutshisa wenziwe ngezitena ze-magnesia ze-chrome, udonga lokuphela kokukhutshwa kwe-slag, umgca we-slag umgca kumacala omabini omgodi wokutshisa kunye nemvula. indawo ekhethiweyo UB605-13R1; i-copper matte Izitena ezidityanisiweyo ze-magnesia ze-chrome zisasetyenziselwa indawo yokukhupha kunye ne-port launder yobhedu. Ezinye iindawo ezifana ne-oven bottom kunye nophahla lwesithando somlilo zonke zikhethwe ngokuthe ngqo kunye ne-magnesia-chromium yokudlulisa isithando somlilo ezantsi izitena eziphezulu ze-alumina kunye nezixhobo eziphikisayo ezingenakulinganiswa, ukwenzela ukuba indawo ye-refractory ikwazi ukukhuthazwa ngokuthe ngcembe kwaye ngokuthe ngcembe.

Phakathi kwabo, i-furnace ye-Nora Randa esanda kwakhiwa yafakwa kwimveliso yeentsuku ze-316, ibeka irekhodi yehlabathi kwixesha lokuvelisa uhlobo olufanayo lwesithando somlilo. Emva kokulungiswa, i-refractory material yasetyenziselwa ukulungelelanisa ukulungelelaniswa, kwaye imveliso eqhubekayo yayiziintsuku ezingama-494, ezikufutshane nerekhodi yehlabathi leentsuku ezingama-498 zobomi besithando somlilo esifanayo.
