Ishidi lesimbi elisheshayo
I-High speed steel centrifugal composition roll iyinsimbi ye-alloy ephezulu ye-carbon lapho ungqimba olungaphandle lugcina khona i-Cr Mo W V Ni ne-Nb, futhi isakhiwo esinzima se-carbide sifakwe ezakhiweni ze-tempered martensite ukuze kulawulwe okuqukethwe kwe-carbon kanye nokwelashwa kokushisa okuphelele, kuthuthukiswe ukumelana nokugqoka nokumelana nokukhathala kokushisa. Isakhiwo sesikhumba esine-oxide enobubanzi obuncane sigcina ingcindezi ye-balance ephansi.

Uhlelo lokusebenza
I-High speed steel roll iyasetshenziswa kabanzi kumaroli wokusebenza we-hot-rolled strip steel F1-F3 mills, umshini wokuphothula wokugaya we-high speed wire mills kanye ne-re-bar finish rolling split stand.
Iphakheji ye-High speed steel roll
Ngokungeza izinto ezifana ne-tungsten, i-molybdenum kanye ne-vanadium, ubunzima bungafinyelela ku-90-95HSD, kanti impilo yokusebenza ingama-2-3 izikhathi kunezindandatho ze-Cr5 ezijwayelekile. Ibonisa ubunzima obuphezulu, ukumelana nokugqoka okuphezulu kanye nokuzinza okuhle kokushisa. Insimbi esheshayo iqukethe inani elikhulu lezinto zokuhlanganisa ezifana ne-tungsten, i-molybdenum, i-chromium kanye ne-vanadium, zakha ama-carbides ayinkimbinkimbi, okwenza ikwazi ukugcina ubunzima obuphezulu namandla ezingeni eliphezulu lokushisa futhi ibekezelele izivinini eziphezulu zokugaya namandla okugaya.
Uhlaka lokusetshenziswa: Ikakhulukazi isetshenziswa ekugudlweni kwemikhiqizo ephakeme-ukucacisa futhi ephezulu-ukusebenza (njengensimbi yezimoto enamandla aphezulu), efana nensimbi ye-strip ethinnyi kakhulu, insimbi ye-alloy ye-strip enembile, njll. Ikhethekile kakhulu ekugudlweni okusheshayo nasekugudlweni kwezinto ezinzima ukujika.
