Emikhakheni yezimboni eshisa kakhulu njengokwenza insimbi, ukukhiqizwa kwesithando sikagesi se-arc (EAF), ukucwengisisa amaladle, kanye nokuncibilikisa insimbi okungeyona i-ferrous, izinto ezingasebenzi kahle ezitholakala eshalofini zivame ukwehluleka ukuhlangabezana nezimo zokusebenza ezihlukile.izitini ze-magnesium carbonkungase kungabi nokusebenza okuqondiwe, okuholela ekuhlulekeni njalo kwendwangu, isikhathi eside sokungasebenzi, izindleko zokulungisa ezikhuphukile, kanye nokusebenza kahle kokukhiqiza okuphazamisekile. Izitini ze-magnesia carbon (MgO-C) ezenziwe ngokwezifiso zixazulula la maphuzu obuhlungu ngokuletha izixazululo eziqinile eziklanyelwe ngokuphelele ukuze zifane nomklamo wakho oqondile wesithando, izinga lokushisa lokusebenza, ukwakheka kwe-slag, imijikelezo yokushaqeka kokushisa, kanye nokuqina kokuguguleka.
Izitini ze-Magnesia carbon ziyizinto ezihlanganisiwe zekhwalithi ephezulu ezihlanganisa i-magnesia ehlanganisiwe noma exutshwe ngobumsulwa obuphezulu (i-MgO) ne-graphite yemvelo ye-flake, eqiniswe ngama-antioxidants akhethekile (i-aluminium, i-silicon, noma i-boron carbide powders) kanye nezihlanganisi ezisebenza kahle kakhulu. Le nhlanganisela eyingqayizivele inikeza ukumelana okumangalisayo nokuguguleka kwe-slag eyisisekelo, ukushaqeka kokushisa, ukuguqulwa kokushisa okuphezulu, kanye ne-oxidation—izici ezibalulekile zokusinda ezindaweni zezimboni ezinzima kakhulu. Ukwenza ngokwezifiso kuthuthukisa lokhu kusebenza, kulungisa yonke into eguquguqukayo ukuze ivumelane nezidingo zakho zokusebenza ezithile, kunokuphoqa inqubo yakho ukuthi ivumelane nomkhiqizo ofanelana nosayizi owodwa.
Izinketho Zokwenza Ngokwezifiso Eziyinhloko Zokusebenza Okuphezulu Kokusebenza
Inqubo yethu yokukhiqiza izitini ze-magnesia carbon eyenziwe ngokwezifiso iqala ngokuhlolwa okuningiliziwe kwemishini yakho kanye nomsebenzi wakho endaweni noma kude. Silungisa yonke ipharamitha ebalulekile ukuze senze ngcono ukuqina, isikhathi sokuphila, kanye nokusebenza kahle kwezindleko: okuqukethwe kwekhabhoni okulungisekayo (amabanga ekhabhoni aphansi, ajwayelekile, noma aphansi kakhulu) ukuze kulawulwe i-oxidation kanye nokuhambisana kwebanga lensimbi; ubuningi kanye ne-porosity eyenzelwe wena ukumelana nokungena kwe-slag kanye nokuguguleka komshini; izimo, osayizi, kanye nemiklamo exhumene ukuze kulingane kahle ulwelwesi lwesithando, kususwe izikhala kanye namaphuzu abuthakathaka; izinhlelo ezikhethekile ze-antioxidant zokwandisa impilo yesevisi ezindaweni ezine-oxygen ephezulu; kanye nokukhethwa kwe-binder (i-resin noma i-pitch-bonded) ukuze kuthuthukiswe ukuzinza kokushisa kanye nobuqotho besakhiwo.
Lezi zinguquko ezenziwe ngokwezifiso ziletha izinzuzo zebhizinisi ezilinganisekayo. Izitini ze-MgO-C ezenziwe ngokwezifiso zandisa kakhulu impilo yomkhankaso wesithando somlilo, zinciphisa imvamisa yokuphinda zibekwe kabusha futhi zinciphise isikhathi sokungasebenzi ngamaphesenti angama-50 uma kuqhathaniswa nezitini ezijwayelekile. Ukumelana okukhulu kokushaqeka kokushisa kunciphisa ukuqhekeka nokuqhekeka, kuyilapho ukuvikelwa kwe-slag okuqondisiwe kuvimbela ukuguguleka kwendwangu ngaphambi kwesikhathi, kunciphisa izindleko zokufaka esikhundleni ezingapheli isikhathi eside. Usayizi oqondile owenziwe ngokwezifiso uphinde usheshise ukufakwa, kunciphisa isikhathi somsebenzi kanye nokubambezeleka kokukhiqiza—okubalulekile ekuhlangabezaneni nezinhlelo zokukhiqiza eziqinile.
Izicelo Ezifanele Zezitini Ze-Magnesia Carbon Ezingokwezifiso
Izitini ze-carbon ze-magnesia ezenziwe ngokwezifiso zenzelwe izindawo ezigugile kakhulu nezishisa kakhulu lapho izinto ezijwayelekile zokungaguquguquki zingaphumeleli khona. Izinhlelo zokusebenza eziphezulu zifaka phakathi izindonga nophahla lwesithando se-EAF, imigqa ye-ladle slag kanye ne-lining yokusebenza, i-linings yokuguqula, izingxenye zesithando sokucwenga, kanye nemishini yokuncibilikisa insimbi engenansimbi. Siphinde sakha izinhlobo ezikhethekile zezimo zokusebenza ezihlukile, njengezitofu zezimboni ezishisa kakhulu, izitofu zokushiswa kwemfucuza, kanye neminye imishini yokushisa enzima edinga ukuvikelwa okwenziwe ngokwezifiso kokungaguquguquki.
Kungani Kufanele Usebenzisane Nathi Ngezidingo Zakho Zezitini Ze-MgO-C Ezenziwe Ngokwezifiso
Njengomkhiqizi ohamba phambili we-refractory eyenziwe ngokwezifiso, sihlanganisa amashumi eminyaka obuchwepheshe embonini, ukulawulwa kwekhwalithi okuqinile, kanye nobuchwepheshe bokukhiqiza obuthuthukisiwe ukuze sinikeze izitini ze-magnesia carbon ezenziwe ngokwezifiso ezithembekile nezisebenza kahle kakhulu. Sisebenzisa kuphela izinto zokusetshenziswa ezihlanzekile kakhulu, ngokuhlanganiswa okuzenzakalelayo kanye nokwakheka kokucindezela okuphezulu ukuqinisekisa ubuningi obuhambisanayo kanye nokufana kwesakhiwo kuyo yonke i-oda elenziwe ngokwezifiso. Ithimba lethu lobuchwepheshe lisebenza eduze nawe kusukela ekubonisaneni kokuqala kuya ekulethweni kokugcina, lihlinzeka ngomklamo owenziwe ngokwezifiso, ukuhlolwa kwesampula, kanye nokusekelwa kwangemva kokuthengisa ukuqinisekisa ukuhambisana okugcwele kanye nokusebenza. Sinamathela ezindinganisweni zomhlaba wonke ze-refractory, siqinisekisa ukuthi zonke izitini ezenziwe ngokwezifiso zihlangabezana nezidingo zokuphepha okuqinile, ukuqina, kanye nokumelana nokushisa.
Ungavumeli izinto ezijwayelekile zokuphikisa zinciphise ukusebenza kahle kwakho noma zandise izindleko zakho zokulungisa. Tshala imali ngezitini ze-magnesia carbon ezenzelwe inqubo yakho ehlukile, futhi uvule impilo yesithando eside, isikhathi esiphansi sokungasebenzi, izindleko ezincishisiwe, kanye nokukhiqizwa okuzinzile. Noma ngabe udinga iqembu elincane lezitini ezibunjwe ngokukhethekile noma isisombululo esigcwele sokufakwa kwesithando, siletha imikhiqizo yokuphikisa eyenzelwe wena esebenza ngaphansi kokushisa okukhulu kanye nengcindezi.
Xhumana nathi namuhla ukuze uxoxe ngezidingo zakho zesitini se-magnesia carbon ezenziwe ngokwezifiso, ucele ukubonisana kwamahhala kwezobuchwepheshe, noma uthole isilinganiso esenziwe ngokwezifiso. Vumela ochwepheshe bethu abaphikisayo baklame ikhambi eliphakamisa imisebenzi yakho yokushisa okuphezulu liye emazingeni amasha okuthembeka nenzuzo.
