1. Cov khoom txhais thiab cov khoom tseem ceeb
Q: Dab tsi yog ovm 519 5135 cov yeeb nkab?
A:
5135 steel yeeb nkab yog ib qho nruab nrab-high carbon chromium alloy steel seamless yeeb (tsis yog G51350) teev nyob rau hauv Astm ATTM A519 tus qauv. Nws cov tub ntxhais muaj composition yog 0.33% -0.38% carbon thiab 0.80% -1.10% chromium. Cov ntaub ntawv no, dhau los ntawm kev ua haujlwm ntxiv nrog cov pa roj carbon ntau ntau dua lossis muaj zog rau 950 MPa) thiab lub zog tiv thaiv zoo dua (Hardness 52-56 hrc). Nws cov yam ntxwv tshwj xeeb muaj xws li dispersed carbides (tsawg dua los yog sib npaug ntawm 2000-90 mm), ua rau nws haum rau hnyav-thauj khoom ntsuab Cheebtsam.
2. Cov Khoom Siv Cov Neeg Kho Tshuab thiab Cov Lus Qhia
Q: Qhov ntsuas tau ua tiav ntawm 5135 steel yeeb nkab? A:
Hauv lub xeev quenched thiab tempered (880℃roj quenching+ 540 deg℃tempering):
Lub zog cov khoom: tensile zog 950-1150 mpa, zog, tawm lub zog 800-950 MPA
Kev nyuaj: elongation ntau dua los yog sib npaug ntawm 12%, txo thaj chaw ntau dua lossis sib npaug nrog 40%, chav sov cuam tshuam lub zog loj dua los yog sib npaug 28j
Cov Khoom Tshwj Xeeb: Hu Rau Cov Neeg Qoob Lwj (10⁷ Cycles) Ntau dua lossis sib npaug X 100H) Retention tus nqi ntau dua lossis sib npaug rau 75%
3. Raug ntawv thov cov xwm txheej
Q: Cov ntaub ntawv thov ntawm 5135 steel yeeb nkab?
A:
Hnyav-Ua Haujlwm Cov Tsheb: Mining Tsheb Tsav Cov Tshuaj Txhuam, Tank Torque Shafts (yuav tsum xeem dhau mil-s-7100 kuaj)
Cov Khoom Siv Hluav Taws Xob: Cov Cua Turbine Mainthaft Couplings, Hnyav Kav Drilling kav
Kev Lag Luam Machinery: Cov Rolling Rolling Mill Universal Jointal, Hydraulic Phauj (Saum Toj Siab Rau Hrc 55-58)
4. Cov ntsiab lus tseem ceeb rau kev kho cua sov thiab kev ua
Q: Yuav ua li cas thiaj zoo kho kom sov thiab kev ua haujlwm ntawm 5135 steel yeeb nkab? A:
Cov txheej txheem tseem ceeb tswj:
Siv "sub-kub forging + tswj cov txheej txheem txias" (ua zaum zaum kawg forging txias tus nqi 30℃/ s) rau cov qoob loo ua kom huv.
Vuam yuav tsum muaj ER100S-G Hlau, Preheating rau 350℃thiab dehydogenating ntawm 620℃rau 4 teev tom qab vuam.
Siv cov cuab yeej PCBN rau txoj kev tig (txiav ceev 50-70 m / min) kom zam dhau kev nyob hauv thaj chaw npau taws ntawm 300-500 degree.
5. Piv nrog cov ntaub ntawv zoo sib xws
Q: Dab tsi yog qhov txawv ntawm 5135 thiab 5140 thiab 4135 steel kav?
A:
vs {. 5140: 5135 muaj cov ntsiab lus carbon ntau (0.33% -0.38% vs ntawm lub zog thiab tawv, tab sis kuj nce vuam nyuaj.
vs. 4135: 5135 does not contain molybdenum, resulting in an 18% lower cost, but exhibits slightly inferior high-temperature creep performance (>350 degree).
