1.Zinthu: Aloyi 28(N08028,4563,X1NiCrMoCu31-27-4)
Chemical Component:C ≤0.02%;Si：≤1.0%;Mn：≤2.0%;P:≤0.03%;S ：≤0.03%;Cr :26～28%;Ni :30～32%;Momar: 3～40%;Cu .
2.Katundu Wazinthu:
kachulukidwe:8.1g/cm³;
malo osungunuka: 1320-1370 ℃;
mphamvu yowonjezera:1650-2250MPa;
mwayi wopeza:1250-1750MPa;
mlingo wa elongation:25% -45%;
kuuma:35-45HRC
3.Katundu Waukulu:
Kukana kutentha kwa kutentha, kukana kuvala kwakukulu, kukana kwa dzimbiri bwino, kuuma bwino kofiira; Kukana bwino kwa dzimbiri m'malo a asidi amphamvu; Kukaniza bwino kupsinjika kwa dzimbiri kusweka mu hydrogen sulfide (H2S) ndi malo a chloride; Good intergranular dzimbiri kukana; High kukana dzenje ndi dzimbiri mphanga; Weldability wabwino;
4.Alloy 28 Magawo Ogwiritsa Ntchito:
Nthawi zambiri amagwiritsidwa ntchito pazakudya zowononga kwambiri monga makampani opanga mankhwala, ndipo angagwiritsidwe ntchito pokonza mankhwala, zida zowongolera kuipitsidwa, mapaipi amafuta ndi gasi, kukonzanso mafuta a nyukiliya, ntchito zapansi panthaka m'mitsinje yakuya ya sulfure, komanso kukonza mankhwala a phosphoric acid wonyowa, madzi am'nyanja, hydrofluorinated chloride ndi kupanga organic acid ndi zida zotola.
5. Zofunikira pakukonza:
Kulondola kwakukulu kwa makina ndi 0.01mm, kutsirizitsa kwakukulu ndi RA0.6um, ndipo kukhazikika kwa malo onse ozungulira akunja kuli mkati mwa 0.05mm.
6.Machining process:
Zopangira zopangira: sanicro28 ndizitsulo zosapanga dzimbiri zosapanga dzimbiri, zodula, komanso zazikulu, kutalika kwakunja ndi 200MM, kulibe zida zamtunduwu, kugwiritsa ntchito kupangira kupanga kamwana kaubweya, chifukwa cha kuuma kwa zinthuzo, koyenera kwambiri kupangira zinthu zopangira bar ngati chopanda kanthu. Kukula kwa ukonde wa workpiece pambuyo pokonza ndi 200 m'mimba mwake ndi 1028 kutalika, ndipo ubweya wonyengedwa womwe umagwiritsidwa ntchito ndi 210 kunja kwake ndi 1100 kutalika.
Kuvuta kukonza:Chifukwa zakuthupi zimakhala ndi chromium yambiri ndipo zimakhala ndi gawo la molybdenum, zomwe zimapangitsa kuuma kwakukulu kwa workpiece, zomwe zili mu nickel ndizokwera kwambiri, kulimba kwa zinthu kumakhala kwakukulu, kukonzanso kumakhala kovuta, ndipo n'kosavuta kuoneka ngati chip kuswa ndi kukakamira mpeni ndi mavuto a resonance. tsamba, amene amathetsa vuto la processing Mwachangu ndi kumamatira chida, ndi resonance vuto la workpiece ndi kutembenukira tool.Using wapadera mapulogalamu njira, ntchito cyclic kusinthasintha liwiro workpiece ndi liwiro chakudya, chomaliza wangwiro yothetsera vuto resonance.
Kupukutira kovuta: The workpiece viscosity ndi yayikulu, zomwe zimapangitsa zinyalala zazikulu za zinthu zomatira za gudumu lopera, ndipo ndizosatheka kugaya bwino. Pomaliza, chiwembu chomaliza cha lathe chimagwiritsidwa ntchito kumaliza zofunikira zakumapeto kwa RA0.6um.
