Ukufudumeza linyathelo elisisiseko kodwa elibalulekileyo kwimiba emininzi yemveliso yefektri. Ukusuka kunyango lobushushu besinyithi ukuya kwi-ceramic sintering, kunye nokusetyenzwa kwezixhobo ezithile ezikhethekileyo, okuzinzile, okusebenzayo kunye nokuguquguqukayo kwezixhobo zokufudumeza kuyadingeka. Kwezi meko zineemfuno ezingqongqo zobushushu kunye nokuqina,imitha ye-silicon carbideiityhubhu ziba lukhetho lwamashishini amaninzi nangaphezulu ngenxa yeenzuzo zawo ezizodwa.
Abanye abantu banokuba nomdla, yintoni ityhubhu ye-silicon carbide radiation? Ukubeka ngokulula, yinto yokufudumeza kwe-tubular eyenziwe ngokuyininzi ye-silicon carbide ceramics, edla ngokusetyenziswa ngokubambisana neengcingo zokufudumeza, iintambo zokufudumeza kunye nezinye iintsimbi zangaphakathi, kwaye idlala indima "yomtshintshi wokushisa" kwii-kilns zoshishino kunye nezinye izixhobo. Nangona kunjalo, ukungafani kwayo kuxhomekeke ekubeni ayivelisi ngokuthe ngqo ubushushu obuphezulu, kodwa endaweni yoko ngokulinganayo idlulisela ubushushu kwi-workpiece efuna ukufudunyezwa ngendlela ye-radiation ngokusebenzisa izinto zangaphakathi zokufudumeza ezijikelezileyo, ngelixa likhusela amacandelo angaphakathi kwi-atmospheric eyinkimbinkimbi ngaphakathi kwe-oven.
Xa kufikwa kuncedo lweetyhubhu ze-silicon carbide radiation, "ukuxhathisa ubushushu obuphezulu" ngokuqinisekileyo yileyibhile ephambili. Iityhubhu eziqhelekileyo zokufudumeza isinyithi zinokufumana uguquko kunye ne-oxidation kumaqondo obushushu angamakhulu aliqela edigrisi, ngelixa i-silicon carbide ceramics ngokwazo inokumelana nobushushu obuphezulu. Nakwiiziko zobushushu obuphezulu obungaphezulu kwe-1300 ℃, ziyakwazi ukugcina uzinzo lwesakhiwo kwaye azonakaliswa lula. Olu phawu luyivumela ukuba iqhelane neemeko ezininzi zokusetyenzwa kobushushu obuphezulu, obufana neqondo lobushushu le-sintering lezinye iiseramikhi ezikhethekileyo ezihlala zidlula kwi-1200 ℃, kunye ne-silicon carbide radiation tubes inokusebenza ngokuthembekileyo kwiindawo ezinjalo ixesha elide.
Ukongeza kokuchasana nobushushu obuphezulu, "ukuxhathisa i-corrosion" kukwayinto ebalaseleyo kuyo. Kwiinkqubo ezininzi zokufudumeza kwamashishini, kunokubakho i-acidic, i-alkaline gases okanye ezinye izinto ezinobungozi kwi-oven, ezinokutshabalalisa ngokulula izinto zokufudumeza kunye nokunciphisa ubomi benkonzo yezixhobo. Ukuzinza kweekhemikhali zezinto ze-silicon carbide zomelele, kwaye akulula ukusabela ngezi zinto ezitshabalalisayo, oku kuthetha ukuba inokugcina ukuqina okuhle kwi-atmospheres ye-kiln enzima, ukunciphisa ukuphindaphinda kokutshintshwa kwezixhobo, kwaye ekuhambeni kwexesha, kwakhona ukunciphisa iindleko zemveliso kunye nokugcinwa kwamashishini.
Ukongeza, "ukusebenza kakuhle kwe-thermal" yeetyhubhu ze-silicon carbide radiation nazo kufanelekile ukukhankanywa. I-conductivity yayo ye-thermal ilungile, enokuthi idlulise ngokukhawuleza ukushisa okwenziwa yizinto zangaphakathi zokufudumeza kunye nokutshisa i-workpiece nge-radiation. Le ndlela yokufudumeza ayigcini nje ngokutshisa ngokukhawuleza, kodwa iphinda yenza ukuhanjiswa kweqondo lokushisa ngaphakathi kwe-ontini ibe yinto efanayo, ukuphepha ukushisa kwendawo okanye ukushisa okunganeleyo. Oku kubaluleke kakhulu ekuqinisekiseni ukuhambelana komgangatho wokulungiswa kwemveliso. Ngokomzekelo, ekuphathweni kobushushu beendawo zetsimbi, ukufana kweqondo lokushisa kuchaphazela ngokuthe ngqo ukuqina, ukuqina, kunye nezinye iipropathi zamalungu, kunye ne-silicon carbide radiation tubes inokubonelela ngenkxaso ezinzileyo kulo mbandela.
Ewe kunjalo, ukusetyenziswa kweetyhubhu ze-silicon carbide radiation akukho mida. Ngokomzekelo, iindleko zabo ziphezulu kakhulu kuneetyhubhu eziqhelekileyo zokufudumeza isinyithi, kwaye ngenxa yeempawu ze-ceramics, kufuneka ziphephe ukungqubana okukhulu ngexesha lofakelo kunye nokusetyenziswa ukukhusela umonakalo. Kodwa kumashishini aneemfuno eziphezulu zokufudumeza ubushushu, ukubola kokusingqongileyo, kunye nomgangatho wemveliso, uzinzo, ukusebenza kakuhle, kunye nobomi obude obuzisayo buhlala buhlawulela ezi ngxaki zincinci.
Kule mihla, ngophuhliso lwemveliso yemizi-mveliso ukuya ngokuchanekileyo ngakumbi kunye nesiphelo esiphezulu, iimfuno zezixhobo zokufudumeza nazo zikhula rhoqo. Njengeyona nto ibalaseleyo yokufudumeza kwimizi-mveliso, iityhubhu ze-silicon carbide radiation zidlala ngokuthe ngcembe indima enkulu kumasimi anje ngeceramics, metallurgy, kunye ne-elektroniki. Isenokungabonakali njengeetekhnoloji ezisakhulayo, kodwa kanye kanye lo mkhuba wokuthe cwaka "ukunamathela kwisithuba sawo" kwindawo enzima kakhulu eyenza ukuba ibe "yingcaphephe yokumelana nobushushu obuphezulu" kwimveliso yemizi-mveliso, inika iziqinisekiso ezithembekileyo kwiinkqubo ezahlukeneyo zokufudumeza.
