Ekukhiqizweni kwezinto zobumba, i-metallurgy, imboni yamakhemikhali kanye nezinye izimboni, ama-oven ayimishini eyinhloko, kanti izinsika ze-oven ezisekela isakhiwo sangaphakathi sama-oven futhi zithwala imithwalo yokushisa ephezulu zingabizwa ngokuthi “i-skeleton” yama-oven. Ukusebenza kwawo kuthinta ngqo ukuphepha kokusebenza kanye nokuphila kwenkonzo yama-oven. Phakathi kwezinto eziningi zensika, izinsika ze-oven ze-silicon carbide (SiC) ziye zaba ukukhetha okujwayelekile ezimweni zezimboni zokushisa okuphezulu ngenxa yokuzivumelanisa nezimo kwazo okuvelele, okuvikela buthule ukusebenza okuzinzile kwama-oven.
Abantu abaningi bangase babe nokuqonda okungacacile ngalokhoamakholomu e-silicon carbide, kodwa empeleni zingaqondwa “njengesisekelo esiqinile” kuma-oven. I-silicon carbide ngokwayo iyinto enamandla engaphili engeyona eyensimbi ehlanganisa ukumelana nokushisa okuphezulu kwama-ceramics namandla esakhiwo aseduze nezinsimbi. Ivumelaniswa ngokwemvelo nendawo eshisayo ngaphakathi kwama-oven, futhi izinsika ezenziwe ngayo ngokwemvelo zinezinzuzo ezingokwemvelo ekubhekaneni nokushisa okuphezulu kanye nemithwalo esindayo.
Okokuqala, ukuncintisana okuyinhloko kwamakholomu esitofu se-silicon carbide kulele ekumelaneni kwawo okungavamile namazinga okushisa aphezulu kanye nokushaqeka kokushisa. Ngesikhathi sokusebenza kwesitofu, izinga lokushisa langaphakathi lingafinyelela kalula amakhulu noma ngisho nezinkulungwane zama-degree Celsius, futhi izinga lokushisa lishintsha kakhulu ngesikhathi senqubo yokushisa nokupholisa. Amakholomu ezinto ezivamile avame ukuqhekeka kanye nokuguquka ngenxa yokwanda kokushisa kanye nokufinyela kule ndawo, okuholela esakhiweni sesitofu esingazinzile. Ukuqina kokushisa kwezinto ze-silicon carbide kuhle kakhulu, okungamelana nokubhaka okushisa okuphezulu isikhathi eside futhi kumelane nomthelela wokushintsha kwezinga lokushisa okungazelelwe. Ngisho nasemijikelezweni ebandayo neshisayo ephindaphindayo, kungagcina ubuqotho besakhiwo futhi akulimali kalula, kunikeze ukwesekwa okuqhubekayo nokuzinzile kwesitofu.
Okwesibili, amandla ayo amahle okuthwala imithwalo ayenza ikwazi ukuthwala imithwalo esindayo kancane kancane. Isakhiwo sangaphakathi sesithando kanye namandla okuthwala imithwalo yezinto kuzodala ingcindezi yomthwalo eqhubekayo ezinsikeni. Amakholomu ajwayelekile ezinto ezithwala imithwalo esindayo isikhathi eside angase abhekane nokugoba, ukuphuka, nezinye izinkinga, okuthinta kakhulu ukusebenza okuvamile kwesithando. Izinto ze-silicon carbide zinobunzima obukhulu, isakhiwo esiminyene, kanye namandla omshini adlula kakhulu ezinto ezivamile ze-ceramics kanye nezinsimbi. Ingathwala kalula imithwalo ehlukahlukene ngaphakathi kwesithando, futhi ngisho nangaphansi kwezimo zokushisa okuphezulu kanye nemithwalo esindayo isikhathi eside, ingagcina isimo esizinzile futhi igweme izingozi zesakhiwo ezibangelwa amandla okuthwala anganele.
Ngaphezu kwalokho, ukumelana okuhle kakhulu nokugqwala kuvumela namakholomu esitovini se-silicon carbide ukuthi azivumelanise nezimo zokusebenza eziyinkimbinkimbi kakhulu. Ngesikhathi senqubo yokukhiqizwa kwama-oven kwezinye izimboni, kukhiqizwa amagesi agqwalisayo noma uthuli oluqukethe i-asidi ne-alkali. Amakholomu ajwayelekile ezinto ezibonakalayo abonakala kulezi zindawo isikhathi eside azogqwala kancane kancane, okuholela ekunciphiseni amandla kanye nokuphila okufushane kwenkonzo. I-silicon carbide ngokwayo inezakhiwo zamakhemikhali ezizinzile futhi ingamelana nokugqwala kwama-oven agqwalisayo njenge-asidi ne-alkali. Ngisho nasezindaweni ezinzima zokugqwala, ingagcina ukusebenza okuzinzile ngaphandle kokushintsha njalo, kunciphisa izindleko zokugcinwa kwemishini yamabhizinisi.
Kumabhizinisi, ukusebenza okuzinzile kwama-oven kuhlobene ngqo nokusebenza kahle kokukhiqiza kanye nokulawula izindleko, futhi ukukhetha ikholomu ye-oven ethembekile kubalulekile. Amakholomu e-oven e-silicon carbide, anezinzuzo eziningi zokumelana nokushisa okuphezulu, ukumelana nokushaqeka kokushisa, amandla aqinile okuthwala umthwalo, kanye nokumelana nokugqwala, ahlangabezana kahle nezidingo ezidingekayo zama-oven ezimboni. Angaqinisekisa ukusebenza okuphephile kwama-oven, andise impilo yesevisi yemishini, anciphise imvamisa yokugcinwa, futhi abe ukwesekwa kwekhwalithi ephezulu kwamabhizinisi ukuthuthukisa ukuzinza kokukhiqiza.
Njengoba isidingo sokuthembeka kwemishini nokuqina kwayo ekukhiqizweni kwezimboni sikhula, izimo zokusetshenziswa kwezinto ze-silicon carbide nazo ziyanda njalo. Futhi izinsika zama-silicon carbide zizoqhubeka nokusebenza “njengensika ephezulu”, zinikeza ukwesekwa okuqinile kwama-fun ahlukene ezimboni anokushisa okuphezulu futhi zisize amabhizinisi ukuthi athole ukukhiqizwa nokusebenza okuphumelelayo nokuzinzile.
