Ibhulokhi Elakhiwe Ngensimbi Engagqwali ye-AISI 431 | Insimbi Engagqwali Enamandla Aphezulu Engashintshwa
Incazelo emfushane:
Amabhulokhi Ahlanganisiwe Ensimbi Engagqwali angu-431 ayizinsimbi eziqinile ze-martensitic eziqinile kakhulu ezaziwa ngezakhiwo zazo ezinhle kakhulu zemishini, ukumelana okuhle nokugqwala, kanye nokuqina okuphezulu. Lawa mabhulokhi ahlanganisiwe avame ukusetshenziswa ezingxenyeni zokukhiqiza ezidinga amandla kanye nokumelana nokugqwala okulinganiselwe, njengemiphini, isikhunta, izinto zokufaka izindiza, izingxenye zephampu, kanye nehadiwe yasolwandle.
Ibhulokhi Yensimbi Ehlanganisiwe ye-AISI 431:
Ibhulokhi Yensimbi Ehlanganisiwe ye-AISI 431iwumkhiqizo wensimbi engagqwali ye-martensitic enamandla aphezulu, engagqwali, esetshenziswa kabanzi ezinhlelweni zokusebenza ezidinga ukusebenza kahle kakhulu kwemishini kanye nokumelana nokugqwala okulingene. Njengoba inokuqukethwe okuphezulu kwe-chromium ne-nickel, i-431 inikeza ukuqina okuthuthukisiwe, ukuqina, kanye nokumelana nokukala uma kuqhathaniswa namazinga ajwayelekile e-martensitic afana no-410 noma u-420. Lawa mabhulokhi ahlanganisiwe ngokuvamile ahlinzekwa ezimweni ezifakwe i-anneal noma ezicinyiwe nezishisiwe (QT) futhi angathuthukiswa ngomshini ngokwezilinganiso ezichazwe ngamakhasimende. Njengoba ilungele imiphini, izingxenye zepompo, imizimba yamavalvu, kanye nezinto zokufaka amathuluzi, amabhulokhi ahlanganisiwe e-AISI 431 ayisinqumo esihle kakhulu sezimboni ezifana nezindiza, ezolwandle, ezokucubungula amakhemikhali, kanye nobunjiniyela obujwayelekile.

431 Ukwelashwa Kokushisa Kwebhulokhi Yomshini Ongagqwali
Amabhulokhi omshini wensimbi engagqwali angu-431 avame ukuphathwa ngokushisa ukuze kufezwe izakhiwo ezinhle kakhulu zemishini. Izimo ezivame kakhulu yi-Quenched and Tempered (QT) kanye ne-H1150. Ukwelashwa ngokushisa kuthuthukisa amandla ebhulokhi, ukuqina, kanye nokumelana nokugqwala, okwenza lifaneleke ekusetshenzisweni ngokunemba kanye nezicelo zokucindezela okukhulu. Ibhulokhi ngalinye liyacutshungulwa ukuqinisekisa ukufana kwesakhiwo, ukuzinza kobukhulu, kanye nokuqina okuhambisanayo kulo lonke.
1.4057 Ukuqeda Ukusika Okungaphezulu Kwebhulokhi Ehlanganisiwe
1.4057 Ibhulokhi Yensimbi Engagqwali Ehlanganisiwe, eyaziwa nangokuthi i-AISI 431, iyinsimbi engagqwali enamandla amakhulu enezakhiwo ezinhle kakhulu zemishini kanye nokumelana nokugqwala okumaphakathi. Ihlinzekwa ngesimo sayo esihlanganisiwe ngokuqeda kokugaya okungaphezulu, leli bhulokhi linikeza ukunemba okuthuthukisiwe kanye nobuso obubushelelezi, okwenza kube kuhle kakhulu ekusetshenzisweni kwe-CNC noma ekwenziweni ngokunemba. Ukuqeda kokugaya okungaphezulu kuqinisekisa ukuqina okuphansi kobuso (ngokuvamile i-Ra ≤ 3.2 µm), okuvumela ukulingana okungcono, ukulungelelana, kanye nesikhathi sokugaya esincishisiwe ezinhlelweni ezibalulekile.
Ukuhlolwa kobulukhuni obuyi-431 bar
Amabha ethu esikwele ensimbi engagqwali angu-431 ahlolwa ngokuqinile ukuze kuqinisekiswe ukuthi ahlangabezana nezidingo eziqondile zezicelo zezimboni ezisebenza kahle kakhulu. Sisebenzisa ama-profilometers asezingeni eliphezulu, silinganisa inani le-Ra (Isilinganiso Sokugqwala) ngokuhambisana namazinga omhlaba wonke njenge-ISO 4287 kanye ne-ASME B46.1. Lokhu kuhlolwa kuqinisekisa ukuthi ukuqeda kobuso bebha kufaneleka ukusetshenziswa okubalulekile ezimbonini zezindiza, zasolwandle, kanye nobunjiniyela bemishini. Ngokumelana okuhle kokugqwala kanye namandla aphezulu okudonswa, insimbi engagqwali engu-431 ilungele izingxenye ezidinga ukuqina kanye nokunemba kobukhulu. Ukuhlolwa kobugqwala kuqinisekisa ukulungela imishini futhi kuthuthukisa ukuthembeka komkhiqizo ezinhlelweni zokusetshenziswa kokugcina.
Ukugeleza Kokukhiqiza kweBloko Elihlanganisiwe elingu-431
Lena inqubo evamile yokukhiqiza yamabhulokhi ethu ensimbi engagqwali angu-431:
1. Ingot → 2. Ukwakha ngemva kokushisa → 3. Ukusika → 4. Ukwelashwa Kokushisa → 5. Ukuqeda Ukugaya Okungaphezulu → 6. Umkhiqizo Oqediwe
Ibhulokhi ngayinye iqala nge-ingot esezingeni eliphezulu, efudunyezwa futhi ishiswe ukuze kulungiswe isakhiwo sayo sangaphakathi. Ngemva kokusikwa ngosayizi, ibhulokhi iphathwa ngokushisa ukuze kufezwe ubulukhuni nokuqina okufunwayo. Bese kufakwa ukuqeda kokugaya okungaphezulu ukuqinisekisa ukuthi kuyisicaba futhi kunembile ngaphambi kokuhlolwa kokugcina nokulethwa.
