Kucutshungulwa Amabanga Ahlukene
Ibanga D, E (DH32, DH36, EH 32, EH 36)
Uchungechunge lweBanga D no-E (okuhlanganisa i-AH32/36, DH32, DH36, EH32, EH36) amapuleti ensimbi yokwakha umkhumbi adinga ukuqina okuhle kwezinga lokushisa eliphansi nokusebenza okuhle kokushisela. Ipuleti lensimbi lokwakha umkhumbi elinamandla amakhulu lidinga ukwenziwa ngokwejwayelekile ngendlela yokugingqika okulawulwayo nokulawulwayo kokupholisa noma ukwelashwa kokushisa ngemishini ephelele kakhulu. Ngesikhathi esifanayo, ukuhlanzeka kwensimbi yangaphakathi kwamabhilidi anikeziwe kuyadingeka ukuba kube phezulu, ikakhulukazi okuqukethwe kwe-S, P, N, 0 no-H ensimbi kufanele kulawulwe ngokuqinile.
Izinto ze-alloy zengezwe ukuze kuthuthukiswe ukuqina
Ukuze kuqinisekiswe ukusebenza kwamapuleti omkhumbi anamandla amakhulu, kwamukelwa ubuchwepheshe be-micro-alloying. Ngokungeza i-Nb, i-V, i-Ti nezinye izakhi ze-alloying ensimbi, kuhlanganiswe nenqubo yokugoqa elawulwayo, okusanhlamvu kuyacwengwa futhi ukuqina kuyathuthukiswa.
Isiqondiso Sokuthuthukiswa KwePlate Yokwakha Umkhumbi
Amandla aphezulu, ukucaciswa okuphezulu, ngobukhulu nokuphepha komkhumbi, kanye nezinguquko ekucacisweni kwe-coating, isidingo samaphaneli ajwayelekile we-A-class siyancishiswa kancane kancane, futhi isidingo samaphaneli anamandla aphezulu siyakhula, esigxile emikhunjini emikhulu. kwe 5m ububanzi. Ipuleti, 200-300mm ukujiya ekhethekile umkhumbi ibhodi obukhulu.
