ER70S {{-6 yog cov khoom siv vuam hlau dav siv hauv cov hlau thiab cov hlau me me hlau vuam. Nrog nws cov kev ua tau zoo thiab kev siv thoob plaws, nws tau dhau los ua "cov khoom siv hnub qub" hauv kev tsim khoom lag luam. Txhua tus cwj pwm hauv nws lub npe muaj lub ntsiab lus tshwj xeeb: "Er" sawv ntsug rau cov qauv hluav taws xob, thiab "6" sib piv rau cov qauv tshuaj lom neeg thiab cov cai sib txuam.
Cov kev ua tau zoo thiab cov txiaj ntsig
ER70S {{-6 yog cim los ntawm high madorgese thiab cov ntsiab lus siab: thiab muaj xeb ntau yam ntxiv: thiab xeb muaj xeb thiab xeb muaj xeb ntawm cov ntxeem ntxeem. Nws tau ua zoo vuam txheej txheem kev ua tau zoo, ruaj khov, txhawb nqa kev tsim Weld, thiab yog qhov tsim nyog rau CO2 lossis kev nplua nuj (xws li AV + CO2 sib xyaw. Raug cov neeg kho mob tshuab hluav taws xob suav nrog lub zog tensile muaj 550 mpa, thiab elongation ntawm 450, sib tham txog cov qauv hauv ntiaj teb xws li AIMA {16}}. 18.
Deversified Daim Ntawv Teev Npe
Los ntawm kev tsim khoom lag luam rau txiav cov thev naus laus zis, er70s {2}}} Ua rau pom dav:
- Kev tsim khoom lag luam: siv rau ib leeg \/ ntau dua vuam ntawm cov hlau thiab 500 MPA-alloy-alloy cov qauv, tshwj xeeb yog zoo ntawm kev ceev vuam thiab kav dej.
- Kev tawg hauv kev tsim khoom ntxiv: Pab pawg ntawm Nanyang thev naus laus zis University, zoo nkauj} bimetallic qauv ntawm ib txoj kev tshiab rau kev sib txuas ntawm cov ntaub ntawv tsis sib xws.
- Qhov Zoo Txawj Ua Zoo Kev Xyaum Kev Xyaum: Shaanxi Hlau thiab Hlau Pab Txhawb Txoj Kev Tswj Xyuas Tag Nrho, thiab cuam tshuam ntau dua qhov zoo ntawm cov hlau.
SIB sib txawv los ntawm cov khoom lag luam zoo sib xws
Piv nrog ER70s -3} {3}} yog qhov ua tau zoo dua rau cov khoom siv tsis zoo thiab ua yeeb yam zoo dua hauv kev tiv thaiv roj av; Piv nrog ER70s -2, nws muaj lub zog ntau dua thiab tsim nyog rau cov khoom siv thicker.
Kev Lag Luam Outlook
Nrog kev txhim kho ntawm kev ua tau zoo ntawm vuam ua haujlwm thiab ua tau zoo hauv kev tsim cov kev lag luam vuam, cov cuab yeej siv hlau thiab cov khoom siv muaj hlau tsim cov xim zoo nkauj. Yav tom ntej, kev tshawb nrhiav thiab kev nthuav dav ib puag ncig nws txoj kev ua kom tau zoo thiab cov kev siv tshiab yuav txuas ntxiv txhawb kev siv kho tshiab.
Tag
Er70} {-6 Tsis yog tsuas yog vuam hlau, tab sis kuj tseem muaj kev ntseeg tau thiab hloov chaw nyob hauv lub teb vuam. Los ntawm kev ua haujlwm vuam tso tawm los txiav-ntug-ntug txuas ntxiv chaw soj ntsuam, thiab nws txuas ntxiv rau kev sib txuas ntawm kev tsim kho thoob ntiaj teb.
