Imisebenzi ye-tundish nozzles

I-tundish nozzle isetshenziselwa ukuncibilikisa insimbi nokuthululela ku-tundish. Uma isetshenziswa, idinga ukumelana nezinga lokushisa eliphezulu futhi imelane nokugqwala kwensimbi encibilikisiwe, ukuze kuncishiswe umonakalo embhobhweni we-tundish. Kunezinhlobo eziningi nezinto zokwakha ze-nozzle ye-tundish, futhi impahla evamile ye-tundish nozzle iyifindo le-oxidation. Lokhu kungenxa yokuthi i-oxidizer inokumelana okuhle kwezinga lokushisa eliphezulu nokumelana nokugqwala, okungavimba ngokugcwele umthelela wensimbi encibilikisiwe.

Imisebenzi ye-tundish nozzle kanye nezidingo zayo zezinto eziphikisayo:

(1) I-Tundish ngokuyinhloko iyisitsha sokwamukela, ukugcina kanye nokusabalalisa kabusha amanzi e-ladle. Ubuchwepheshe be-metallurgy be-Tundish obufana nokulungisa izinga lokushisa, ukulungisa izakhi ze-alloying zokulandelela kanye nokuthuthukiswa kokufakwayo kuthuthukiswa kancane kancane.

(2) Izinto eziphikisayo ziyadingeka ukuze zibe nokungaguquki okuphansi, kodwa zidingeka ukuthi zimelane nokugqwala kwe-slag yensimbi encibilikisiwe, zibe nokumelana nokushaqeka okuhle kokushisa, zibe ne-conductivity encane yokushisa, ukusebenza kahle kwe-thermal insulation, azinakho ukungcoliswa kokuncibilika. insimbi, futhi kube lula ukubeka nokudiliza.
