Isithando somlilo esifakwe emanzini sisixhobo esibalulekileyo sokunyibilikisa isinyithi esisetyenziselwa ukufudumeza ii-ingots zentsimbi ngaphambi kokuba zijike zibe shushu, ukuqinisekisa ukusasazwa kobushushu obufanayo. Olu hlobo lwesithando luhlala lunesakhiwo esinzulu kwaye lusebenza ngamaxesha athile phantsi kobushushu obuguquguqukayo, apho amaqondo obushushu asebenzayo afikelela kwi-1350–1400°C.
Ngenxa yokubamba ixesha elide, ubushushu obugqithisileyo, kunye noyilo lwegumbi elinzulu, izitofu zokuntywila zifuna uzinzo olugqwesileyo lobushushu, ukusebenza kakuhle kokugquma, kunye nokusebenza kakuhle kobushushu.
Kwiindawo ezifana negumbi lokutshintshiselana kobushushu, umqolo wophahla lwesithando, isigqubuthelo sesithando, kunye nomphezulu obandayo weqokobhe lesithando, izixhobo zokukhusela ezikhaphukhaphu zibalulekile ukulawula ubushushu bomphezulu kunye nokunciphisa ukulahleka kobushushu. Iroli yokukhusela isithando sefayibha ye-ceramic ye-CCEWOOL® inikezela ngesisombululo sokukhusela esisebenza kakuhle esilungiselelwe ezi zicelo zesinyithi.
Iimpawu zeMveliso kunye neenzuzo zezinto ezibonakalayo zeengubo zeCeramic Fiber zeCCEWOOL
Iiroli zokugquma iifayibha ze-ceramic ze-CCEWOOL® ziingubo eziguquguqukayo ezenziwe nge-alumina kunye ne-silica ecocekileyo kakhulu kusetyenziswa ubuchwepheshe banamhlanje be-spun-fiber kunye ne-needling. Ngomgangatho wobushushu oqala kwi-1260°C ukuya kwi-1430°C, zilungele ukugquma ubushushu ngasemva, kwiindawo ezibandayo, nakwiindawo zokutywina izixhobo zesinyithi ezinobushushu obuphezulu. Iingenelo eziphambili ziquka:
•Ukuqhuba kobushushu obuphantsi: Ithintela ngempumelelo ukudluliselwa kobushushu nokuba kumaqondo obushushu aphezulu.
•Ilula kwaye inokugcina ubushushu obuphantsi: Inciphisa ukulahleka kobushushu kwaye ikhawulezisa imijikelo yokufudumeza.
•Ukuguquguquka okuphezulu kunye nokulula kokufakela: Inganqunyulwa, isongwe, kwaye ibunjwe ukuze ifanele izakhiwo ezintsonkothileyo.
•Ukumelana kakuhle nobushushu: Ihlala ixesha elide kwaye iyamelana nokuqhekeka okanye ukubola ngokuhamba kwexesha.
I-CCEWOOL® ikwabonelela ngeengubo zefayibha zeseramikhi ezahlukeneyo ngobuninzi nobukhulu obahlukeneyo, kunye neefelthi zefayibha zeseramikhi ezicinezelwayo, zibonelela ngeendlela eziguquguqukayo zokuhlangabezana neemfuno ezahlukeneyo zoyilo, ukubambelela, kunye nolawulo lobushushu.
Izicelo eziqhelekileyo kunye neMikhwa yoLwakhiwo
1. Ubushushu beGumbi lokuTshintshiselana koBushushu
Njengendawo yokufumana ubushushu obusele kwii-ingots zentsimbi, igumbi lidla ngokusebenza phakathi kwama-950–1100°C. Isakhiwo esidibeneyo esidibanisa ingubo yefayibha yeseramikhi ebekwe ngokusicaba kunye nezinto ezisetyenziswayo apha sisetyenziswa.
Iiroli zokufakelwa kwefayibha yeseramikhi ye-CCEWOOL® zibekwe kwiileya ezi-2-3 (ezinobukhulu obupheleleyo obuyi-50-80mm) njenge-backing insulation. Ngaphezulu, iibhloko ze-modular okanye ezigoqiweyo zibotshelelwe kusetyenziswa iinkqubo ze-engile yentsimbi, nto leyo ebangela ukuba ubukhulu obupheleleyo be-insulation bube yi-200-250mm, nto leyo egcina ubushushu be-furnace bungaphantsi kwama-80°C.
2. Ulwakhiwo lweSigqubuthelo sesithando somlilo
Iziko zokuntywila zanamhlanje zisebenzisa kakhulu izigqubuthelo zengubo ezidityanisiweyo ezinokuphoswa + ze-ceramic fiber.
I-CCEWOOL® ceramic fiber insulation roll isetyenziswa njengomaleko ongasemva ngaphakathi kwesigqubuthelo sentsimbi, idityaniswe nee-refractory castables ukwenza inkqubo enomaleko amabini enciphisa kakhulu ubunzima besigqubuthelo sesithando somlilo, iphucula ukusebenza kakuhle kokuvula/ukuvala, kwaye inciphise ukulahleka kobushushu.
3. Ukhuseleko lokutywina kunye nomphetho
Kwiindawo zokuvala ezijikeleze izivikelo ze-furnace, iindawo zokuphakamisa, kunye neendawo ezivulekileyo, ii-CCEWOOL® ceramic fiber rolls okanye ii-felts zisetyenziselwa ukwenza ii-gaskets okanye ii-flexible sealing grooves, ukuthintela ukuvuza kobushushu kunye nokungena komoya ukuphucula ukuchaneka kolawulo lobushushu.
Njengoko ishishini lesinyithi liqhubeka nokulandela ukonga amandla, izixhobo ezikhaphukhaphu, kunye nokusebenza okuzinzileyo, ukusetyenziswa kwe-CCEWOOL®imiqulu yokukhusela ifayibha yeseramikhikwii-oven zokuntywila ziyaqhubeka nokukhula. Nokuba zisetyenziswa kwigumbi lokutshintshiselana nobushushu, i-furnace cover back, okanye ukuvala kunye nokukhusela umphezulu obandayo, iimveliso zefayibha yeseramikhi ye-CCEWOOL zibonelela ngokukhusela okugqwesileyo kunye nokusebenza okuhlala ixesha elide—zibonelela ngezisombululo zobushushu ezithembekileyo nezisebenzayo kubasebenzisi bokugqibela.
