Izitini Ezinhle Kakhulu Zokujikijela Zezitofu Ze-AOD - Izinhlobo, Izinzuzo kanye Nezicelo

Isithando somlilo se-AOD (Argon Oxygen Decarburization) siwumshini oyinhloko wokukhiqizwa kwensimbi engagqwali kanye nensimbi ekhethekile ye-alloy. Izindawo zokucwenga ze-AOD zinezinga lokushisa eliphakeme kakhulu, ukujikeleza kokushisa okunamandla, ukugqwala okunamandla kwe-alkaline slag, kanye nokuhuzuka komshini. Lezi zimo zokusebenza ezinzima zenza izitini ze-AOD eziphikisayo zibe ngenye yezinto ezibaluleke kakhulu ezisetshenziswayo ezitshalweni zensimbi. Ukukhetha izinhlobo zezitini eziphikisayo ezifanele kwandisa ngqo impilo yenkonzo yokufakwa kwe-furnace, kunciphisa izindleko zokufaka esikhundleni eziphikisayo, futhi kuthuthukisa umkhiqizo wokwenza insimbi iyonke.

Uma ufuna izixazululo ze-refractory lainting eziqinile nezingabizi kakhulu zemikhumbi ye-AOD, ukuqonda izinhlobo zezitini ezivamile ze-AOD refractory kubalulekile. Ngezansi sethula izitini ezisetshenziswa kakhulu nezisebenza kahle kakhulu ze-AOD furniture lainings.

Izitini ze-chrome ze-magnesia eziboshiwe ngqo ziyizinto zokwemba zendabuko nezithembekile kakhulu zezitofu ze-AOD. Zenziwe nge-magnesia ehlanganisiwe ehlanzekile kakhulu kanye ne-chrome ore ngokusebenzisa ukushisa okuphezulu, lezi zitini zinezimbobo eziphansi, ubuningi obukhulu, kanye nokumelana okuvelele kwe-slag. Zimelana ngokuphelele nokuguguleka kwe-slag yensimbi ye-alkaline kanye nokushaqeka okuvamile kokushisa, okuvamile ezinqubweni zokucwenga ze-AOD. Zilungele izikhundla zezihluthulelo ezigugile kakhulu kufaka phakathi umugqa we-slag we-furnace we-AOD, indawo ye-tuyere kanye nolwelwesi olusebenza odongeni oluseceleni, lezi zitini eziphikisayo zivimbela ngempumelelo ukuqhekeka kwe-lining kanye nokulimala kokungena.

Izitini ze-calcium ze-Magnesia, ezaziwa nangokuthi izitini ze-dolomite refractory, sezibe yizindlela ezidumile zokuphepha kwezemvelo esikhundleni sezitini ze-chrome ze-magnesia. Njengoba zingenakho ukungcola kwe-chromium, lezi zitini zinamandla aphezulu okushisa kanye nokumelana okuphezulu kwe-alkaline slag. Ingxenye ye-calcium oxide ingamunca isulfure kanye nokungcola ensimbini encibilikisiwe, okuthuthukisa kakhulu ikhwalithi yensimbi engagqwali. Abakhiqizi abaningi basebenzisa lezi zitini ezingezansi zesithando se-AOD, izintambo ezihlala njalo kanye nezingxenye zodonga lwangaphambili, zivumelana ngokuphelele nemisebenzi yesikhathi eside yokwenza insimbi.

Izitini ze-magnesia ezicwengekile kakhulu zenzelwe izindawo eziphansi zokugqwala nezizinzile zama-AOD furnaces. Njengoba zinokuqukethwe okuphansi kakhulu kokungcola kanye nesakhiwo esincane, zinikeza amandla akhethekile okusebenza kanye nokumelana nomthwalo ophakeme kakhulu. Lezi zitini ezicwengekile ezingabizi kakhulu zivame ukusetshenziselwa izintambo zesithando eziphezulu kanye nezendlalelo zesakhiwo ezisizayo, zihlinzeka ngokuvikelwa okuzinzile kanye nokunciphisa ukutshalwa kwezimali kwezinto ezicwengekile.

Kungani Kufanele Ukhethe Izitini Zethu Eziyi-AOD Eziyi-Refractory Ezingochwepheshe?

Njengomkhiqizi wezitini eziphikisayo ze-AOD ochwepheshe, silawula ngokuqinile ukukhethwa kwezinto zokusetshenziswa kanye nezinqubo zokukhiqiza. Zonke izitini zethu eziphikisayo zesithando somlilo zinokumelana okuhle kakhulu nokushisa, ukusebenza okuqinile kokulwa nokugqwala kanye nokuphila isikhathi eside kwenkonzo. Sinikeza izitini eziphikisayo ezijwayelekile nezinobukhulu obufanele ukuze zifane namamodeli ahlukene esithando somlilo se-AOD kanye nezimo zokusebenza zezimboni. Imikhiqizo yethu isiza izimboni zensimbi ukunciphisa isikhathi sokungasebenzi kwemishini, ukunciphisa izindleko zokulungisa kanye nokukhulisa izinzuzo zokukhiqiza.

Imicabango Yokugcina

Izindawo ezahlukene zezitofu ze-AOD zidinga izinto zezitini eziphikisanayo ezifanayo. Izitini ze-Magnesia chrome, izitini ze-dolomite kanye nezitini ze-magnesia ezihlanzekile kakhulu zimboza zonke izidingo zokusebenza kanye nezihlala njalo zokwenza insimbi ye-AOD. Ukuze uthole izixazululo ze-AOD eziphikisanayo zekhwalithi ephezulu, eziqondile efektri, zizwe ukhululekile ukuxhumana nathi ukuze uthole izingcaphuno ezenziwe ngokwezifiso kanye nesiqondiso sobuchwepheshe sochwepheshe.
