1. Cov khoom txhais thiab cov khoom tseem ceeb
Q: Dab tsi yog ovm 519 4063 cov yeeb nkab?
A:
4063 steel yeeb nkab yog cov pa roj carlicon-manganese alloy steel seamless yeeb (uns g40630) teev nyob rau hauv Astm ATTM A519 tus qauv. Nws cov tub ntxhais muaj pes tsawg leeg yog: 0.60% -0.65% carbon, 0.70% -0.90% Manganese, thiab 1.80% -2.20% silicon. Cov ntaub ntawv no, los ntawm nws cov kev tsim tshwj xeeb ntawm silicon thiab nruab nrab ultome, sib txuas tshwj xeeb nrog kev ua kom zoo heev uas muaj kev ntxhov siab cyclic cyclic. Nws cov yam ntxwv tom qab-quenching paib lub zog ntau dua 1500 MPa, thiab nws cov modulus loj heev yog 15% -20% siab dua li ntawm lub caij nplooj ntoo hlav caij nplooj ntoos hlav.
2. Cov Khoom Siv Cov Neeg Kho Tshuab thiab Cov Lus Qhia
Q: Qhov ntsuas tau ua tiav ntawm 4063 cov yeeb nkab steel?
A:
Nyob rau hauv cov roj quenching thiab nruab nrab-kub tempering (450 degree), 4063 mpa, yog ib qho siab dua ntawm 8% lossis ib qho kev txo qis ntawm 35% lossis siab dua. Nws cov kev txwv tsis pub dhau (10⁷ mus ntev) yog li 55% -60% ntawm lub zog tensile, thiab nws cov hysastic hysteresis poob qis dua 3%. Tom qab cov kev pabcuam ntev ntev ntawm 300 degree, nws txoj kev ntxhov siab relaxent tsawg dua los yog sib npaug rau 5% (Faround rau tias ntawm lub caij nplooj ntoo hlav caij nplooj ntoos hlav.
3. Raug ntawv thov cov xwm txheej
Q: Qhov kev siv ntawm 4063 steel hlau?
A:
Kev Thauj Mus Los: Kev Ceev Ceev Kev Ncua Kev Kawm Tawm Qog, Hnyav-Lub Tsheb Tsheb Springs
Cov Khoom Siv: Cov Xovxwm Loj Poob Siab Ua Dej Springs, Roj Drilling Tool Coil Springs
Cov Khoom Siv Zog: Nuclear Fais Valve Valve Rov Qab Springs, Cua Turbine Suab Suab Suab Torsion Springs
Kev Lag Luam Tub Rog: Cov dav hlau tsaws iav Cushion Springs, Coj Riam Phom Zog Chaw Cia Muag Springs (yuav tsum ua raws li Mil-8516)
4. Kev kho cua sov thiab ua cov ntsiab lus tseem ceeb
Q: Yuav ua li cas thiaj zoo kho kom sov thiab ua haujlwm ntawm 4063 cov yeeb nkab steel?
A:
Qhov "thermomechanical thermal kho mob (TMT)" txheej txheem kub, cov yeeb nkab yog kev kos duab kub, thiab thaum kawg kub ntawm 400℃rau 2 teev. Cov txheej txheem no tuaj yeem kho cov mov loj rau astm qib 10 thiab nce txoj kev txwv ywj ntawm 25%. Cov kev saib xyuas kev ua tiav: Vuam yuav tsum tau Er110S-G Hlau thiab Preheating rau 350 degree. Tig tau yuav tsum CBN cov cuab yeej (txiav ceev 30-40 m / min). Kub txoj kev ntsuas kub yuav tsum tau tswj hwm ntawm 850-950 degree.
5. Piv nrog cov ntaub ntawv zoo sib xws
Q: Dab tsi yog qhov sib txawv ntawm 4063 thiab 5160 thiab 9260 tus kav dej hlau?
A:
vs {. 5160}: 4063 muaj cov ntsiab lus silicon ntau dua (1.80% ntxiv rau kev ntxhov siab tsis kam tab sis txo qis kev ua haujlwm kub.
vs . 9260}: 4063 muaj cov ntsiab lus carbon ntau dua (0.64%
Cov ntawv thov tsis yooj yim: nws tsis tuaj yeem hloov 17-7phphph hauv ib puag ncig muaj kev tiv thaiv ib puag ncig uas hloov pauv rau 300m rau ultra-high-zog qauv qauv.
