Ukukhetha okufanelekileizitini ze-magnesium carbonAma-oven ezimboni kanye nama-oven ashisa kakhulu anquma ngqo impilo yesevisi ye-furniture, ukuzinza kokusebenza, kanye nokusebenza kahle kwezindleko zokukhiqiza. Abasebenzi abaningi basefektri bavame ukubhekana nezinkinga ezifana nokukhuhla izitini, ukuguguleka okukhulu kwe-slag, kanye nomonakalo wangaphambi kwesikhathi wezinto ezimelana nokushisa. Isizathu esiyinhloko ukuthi bayahluleka ukuhlanganisa izimo zokusebenza zangempela ze-furniture lapho bekhetha izitini ze-magnesia carbon futhi bangazinaki imingcele yesici esiyinhloko se-furniture.
Okokuqala, fanisa izinga lezitini ngokwezinga lokushisa lokusebenza okuqhubekayo kwesitofu. Kuma-furnace ensimbi anemithwalo ephezulu kanye nama-rotary kiln asebenza kahle ngaphezu kuka-1700°C isikhathi eside, kuyadingeka ukukhetha izitini ze-magnesia carbon ezihlanganiswe ngobumsulwa obuphezulu ezinokuqukethwe kwe-MgO okungaphezu kuka-97% kanye namafomula e-anti-oxidant alungiselelwe kahle. Izitini ezinjalo zinganikeza amandla okushisa aphezulu azinzile futhi zigweme ukuthamba kanye nokuguquguquka ngaphansi kwamazinga okushisa aphezulu kakhulu esikhathi eside. Kuma-furnace aphakathi nendawo naphansi aphakathi nendawo anokuvalwa okuvamile kanye nemijikelezo yokushintshashintsha kwezinga lokushisa, izitini ze-magnesia carbon zezinga eliphakathi nendawo ezinokumelana nokushaqeka kokushisa okulinganiselayo zanele, okunganciphisa ngempumelelo izindleko zokuthenga ezingadingekile.
Okwesibili, gxila ekujuleni kokuguguleka kwe-slag kanye nesimo somkhathi ngaphakathi kwesithando. Ezingxenyeni zesithando ezithintana ne-slag eqinile encibilikisiwe ye-alkaline (njengemigqa ye-slag ye-ladle kanye ne-linings ye-melting zone), izitini ze-magnesia carbon ezine-high density kanye ne-low-porosity kufanele zikhethwe ukuze kuvinjwe ukungena kwe-slag futhi kumelwane nokuguguleka kwamakhemikhali. Ezindaweni zesithando ezinokuqukethwe okuphezulu kwe-oxygen futhi ezithambekele ekufakweni kwe-carbon oxidation, izitini ze-magnesia carbon ezihlanganisiwe ezingezwe ngama-anti-oxidants asezingeni eliphezulu kufanele zikhethwe ukuze kuncishiswe ukulahleka kwe-carbon futhi kugcinwe ubuqotho besikhathi eside besithando esingenakuphikiswa.
Okwesithathu, cabanga ngokucindezeleka komshini kanye nemijikelezo yokushisa evamile yezingxenye ezibalulekile zesithando somlilo. Ezindaweni zomthelela, iziqongo zesithando somlilo, kanye nezingxenye ezine-cold-heat switching evamile, kufanele kukhethwe izitini ze-magnesia carbon ezifanelekile ezinokuqukethwe kwekhabhoni okufanelekile ukuze kuthuthukiswe ukumelana nokushaqeka kokushisa kanye nokusebenza kokulwa nokuqhekeka, kuvinjwe ngempumelelo imifantu kanye nokuchitheka kolwelwesi lwesithando somlilo ngesikhathi sokusebenza kwansuku zonke kwesithando somlilo.
Ukukhetha okuthembekile kwezitini ze-magnesia carbon akusikho mayelana nokuphishekela ngokungacabangi ukufakwa kwe-stacking ephezulu, kodwa mayelana nokulingana okuqondiwe ngokuya ngokushisa kwangempela, izici ze-slag, umjikelezo wokusebenza kanye nomthwalo womshini we-oven yakho. Izixazululo zethu zezitini ze-magnesia carbon ezenziwe ngokwezifiso eziwuchungechunge oluphelele zifanele izinhlobo ezahlukene zezitini zezimboni, zinikeza ukuhlolwa kwepharamitha yesimo sokusebenza samahhala kanye nesiqondiso sokukhetha ubuchwepheshe somuntu ngamunye, kusiza amafektri ukuthi andise impilo yesevisi yezindwangu zesithando ngo-30% futhi anciphise ukulahleka okuphelele kwezinto ezingafuneki. Uma udinga ukuthola uhlelo lokukhetha olukhethekile kanye nesilinganiso esinembile, sicela uzizwe ukhululekile ukubuza. Sizophendula ngokushesha ukuze sikunikeze imikhiqizo yezitini ze-magnesia carbon engabizi kakhulu kanye nokusekelwa kobuchwepheshe bochwepheshe, futhi sisebenzisane ukunciphisa izindleko zakho zokukhiqiza nezokusebenza.
