Indima Yezimo Ze-Fiber Eziguquguqukayo Ezithuthukisiwe Ekuphathweni Kokushisa

Izithando zokushisa zaselabhorethri zidlala indima ebalulekile ezinhlobonhlobo zezicelo zokushisa okuphezulu ocwaningweni lwesayensi kanye nokukhiqizwa kwezimboni. Lezi zithando zisebenza emazingeni okushisa aphezulu, zidinga ukulawulwa okunembile kanye nokufakwa kokushisa okuthembekile. Izithando zokushisa zamapayipi kanye nezithando zamakamelo ziyizinhlobo ezimbili ezivamile, ngayinye ikhonza imisebenzi ehlukile ngaphakathi komongo obanzi wemisebenzi yokushisa okuphezulu. Izinselele lezi zithando ezibhekene nazo zifaka phakathi ukugcina ukusebenza kahle kwamandla kanye nokufinyelela ukusatshalaliswa kokushisa okuqhubekayo, kokubili okungathinta ikhwalithi yezinqubo zesayensi kanye nomkhiqizo wezimboni.

Izithando zamapayipi zakhiwe ngesimo esiyindilinga, ngokuvamile zisetshenziselwa ukuhlola okuncane lapho kudingeka khona ukulawulwa kokushisa okunembile. Lezi zithando zingasebenza ngokuvundlile, ngokuma, noma ngama-engeli ahlukahlukene, okuvumela ukuguquguquka ekusethweni kwelebhu. Izinga lokushisa elijwayelekile lezithando zamapayipi liphakathi kuka-100°C no-1200°C, kanti amanye amamodeli akwazi ukufinyelela ku-1800°C. Ngokuvamile asetshenziselwa ukwelapha ukushisa, ukuthulula, kanye nokusabela kwamakhemikhali.
Isithando somlilo seshubhu esijwayelekile esenzelwe izilungiselelo zelebhu sinezilawuli ezihlelekayo ezinezilungiselelo zezingxenye eziningi, ezinikeza ukulawula okunembayo kwezinga lokushisa. Izintambo zokushisa zivame ukugoqwa zizungeze ishubhu, okuvumela ukushisa okusheshayo nokusatshalaliswa kwezinga lokushisa okuhambisanayo.

Izithando zegumbi ngokuvamile zisetshenziselwa izinhlelo zokusebenza ezinkulu, zinikeza indawo ebanzi yokushisa kanye nezinto zokushisa ezinezinhlangothi eziningi ukuze kugeleze ukushisa okuhambisanayo kulo lonke igumbi. Lezi zithando zingafinyelela amazinga okushisa afinyelela ku-1800°C, okwenza zifanelekele ukunamathela, ukufudumala, kanye nezinye izinqubo zokushisa okuphezulu. Isithando segumbi esivamile sisebenza ezingeni lokushisa eliphezulu elingu-1200°C futhi sinokufudumeza okunezinhlangothi ezinhlanu ukuze kusatshalaliswe izinga lokushisa elilinganayo.

Izinselele Emisebenzini Yokushisa Okuphezulu
Izitofu zelebhu zidinga ukuvikela okusebenzayo ukuze zilondoloze ukusebenza kahle kwamandla nokuqinisekisa ukuphepha kwezingxenye zesitofu. Ukuvikela okunganele kuholela ekulahlekelweni okukhulu kokushisa, ukusatshalaliswa kokushisa okungalingani, kanye nokusetshenziswa kwamandla okwandisiwe. Lokhu, kungathinta ikhwalithi yezinqubo ezenziwayo futhi kufinyeze isikhathi sokuphila kwezingxenye zesitofu.

Izimo Ze-Fiber Engaguquki Eyenziwe Nge-CCEWOOL®
Izimo Ze-Fiber Engaguquki Eyenziwe Nge-CCEWOOL®zenzelwe ukubhekana nezinselele zokushisa ezibhekene nezitofu zaselabhorethri. Lezi zakhiwo zingamelana namazinga okushisa aphezulu, ngokumelana okufika ku-1800°C, okwenza zifaneleke ukusetshenziswa okudingakalayo njengokufaka i-vacuum annealing, ukuqinisa, kanye nokufaka i-brazing. Amandla okwenza ngokwezifiso izimo ze-CCEWOOL® azivumela ukuthi zilungiselelwe ukuhlangabezana nezidingo ezithile zamakhasimende, zigxile ekubunjweni nasekufakweni kwentambo evikelayo. Lokhu kuqinisekisa ukuhlanganiswa okungenamthungo emiklamo yezitofu ezikhona, kufaka phakathi izitofu ze-muffle, izitofu zamakamelo, izitofu eziqhubekayo, nokuningi.

Ngaphezu kwezinto ezijwayelekile zefayibha ye-ceramic, i-CCEWOOL® inikeza izimo zentambo ezingamelani nefayibha ye-polysilicon ukuze kusetshenziswe izinhlelo zokusebenza ezidinga ukumelana nokushisa okuphezulu. Le nto ethuthukisiwe inikeza ukufudumala okuphezulu, okuholela ekulahlekelweni okuncane kokushisa kanye nokusebenza kahle kwamandla okuthuthukisiwe. Ukuqina kwalezi zinto kuvimbela ukuguquguquka futhi kugcina ubuqotho bokushisa ngesikhathi sokusebenza kokushisa okuphezulu, kwandise isikhathi sokuphila kwezingxenye zesithando.

Kulula Ukufakwa Nokunakekelwa
Izimo ze-CCEWOOL® Vacuum Formed Refractory Fiber zenzelwe ukufakwa kalula, okuyinto ebalulekile ezithandweni zelebhu lapho isikhathi sokungasebenzi singathinta kakhulu umkhiqizo. Inketho yokufaka i-hardener eyenza i-vacuum noma i-refractory mortar inikeza isivikelo esengeziwe, iqinisekisa ukuqina ezimweni ezinzima zezimboni. Le nqubo yokufaka elula ivumela izithando ukuthi zibuyele ekusebenzeni ngokushesha ngemva kokulungiswa noma ukulungiswa, okunciphisa isikhathi sokungasebenzi kanye nezindleko zokusebenza.

Isiphetho
Izithando zokushisa zaselabhorethri zibalulekile ekusetshenzisweni okuningi kwezinga lokushisa eliphezulu, futhi ukusebenza kwazo kuncike ekulawulweni kwezinga lokushisa okunembile kanye nokufakwa kokushisa okusebenzayo. I-CCEWOOL® Vacuum Formed Refractory Fiber Shapes inikeza ikhambi eliphelele, elihlinzeka ngokumelana nezinga lokushisa eliphezulu, ukwenza ngokwezifiso, kanye nokusebenza kahle kwamandla. Ngokufaka lezi zinhlobo ezithandweni zelabhorethri, ungafinyelela ukusebenza okuhle kakhulu, unciphise ukulahlekelwa ukushisa, futhi ulondoloze indawo eshisayo ezinzile. Lokhu kuholela enkambisweni yezimboni esebenza kahle futhi ethembekile, enegalelo ekunciphiseni izindleko zokusebenza kanye nokwandisa isikhathi sokuphila kwezingxenye zesithando.
