1.What yog qhov ua yeeb yam ntawm Q235 Khoom Siv Cov Pob Zeb Bars?
Lub zog thiab tawv: Cov txiaj ntsig zoo yog hais txog ntawm 235MPA, nrog lub zog nruab nrab, muaj peev xwm ua tau zoo, thiab haum rau cov kabmob dav dav.
Weldability: cov ntsiab lus carbon: ≤ {{0. 22%), kev siv vuam ua tau zoo heev, thiab nws tsis yooj yim los ua cov kab nrib pleb Nws yog feem ntau siv rau cov txheej txheem uas yuav tsum tau siv rau ntawm qhov chaw txhawb nqa (xws li lub tsev txhawb nqa thiab cov saib xyuas zoo).
Corrosion Kuj: lub galvanized txheej yuav ua tau zoo tiv thaiv corrosion, tab sis cov corrosion tsis kam ntawm substrate nws tus kheej yog nruab nrab. Nws ua tau zoo hauv noo noo lossis tsis haum rau cov muaj kua qaub thiab cov chaw alkali.
Daim Ntawv Thov Kev Cai: Tsev qauv qauv, cov khoom siv hluav taws xob zoo ib yam (xws li bolts thiab txiv ntoo muaj kev lag luam (xws li rooj tog.
2.What yog qhov kev ua yeeb yam ntawm galvanized round hlau tau ua los ntawm Q345 cov khoom siv?
Lub zog thiab tawv: lees lub zog ≥ 345MPA, txog 40% ntau dua li Q235, zoo dua li cov kabmob loj (xws li txuas hniav thiab crane lug).
Weldability: muaj me me ntawm alloy cov ntsiab (xws li MN), zoo li Weldability, xws li Weldability yuav tsum tau them rau kev tswj hwm lub vuam ntsuas (xws li preheating kub) kom tsis txhob txias.
Corrosion Kuj: cov txheej txheem tiv thaiv rau cov atmospheric corrosizer yog qhov tsim nyog ntxiv rau tom qab galwhwards thiab sab nraum zoov cov khoom siv hnyav thiab kev xa cov yees).
Daim Ntawv Thov Zaj Dab Tsi: Choj engineering, cov neeg siv hluav taws loj, cov hlab ntsha siab, thiab nkoj nkoj.
3.Qhov yog qhov ua tau zoo ntawm 45 # steel (nruab nrab cov pa roj carbon hlau)?
Lub zog thiab tawv: Cov pa roj carbon yog txog 0. 45%. Tom qab quenching thiab tempering, lub zog (tensile zog ≥ 600MPA) thiab kev nyuaj siab txhim kho. Lub Tawv yog qhov nruab nrab, uas yog qhov haum rau qhov uas yuav tsum tau hnav tsis kam thiab muaj zog siab.
Kev Ua Tau Zoo: Nws tuaj yeem raug kev kho kom sov xws li quenching thiab tempering. Lub saum npoo hardness tuaj yeem ncav cuag hrc 40-45, tab sis cov weldability}, thiab feem ntau nws yuav tsum tau ua ntej vuam thiab cua sov khaws cia tom qab vuam.
Corrosion Kuj: cov corrosion tsis kam ntawm cov khoom siv hauv paus yog zoo ib yam li ntawm Q235. Tom qab galvanizing, nws tsuas yog pub rau ntawm zinc txheej rau corrosion tiv thaiv. Nws yog qhov haum rau cov khoom siv tshuab ntau dua li qhov muaj zog corrosive ib puag ncig.
Daim Ntawv Thov Kev Ua Si: Cov Khoom Siv Txhua Yam (xws li siv lub tshuab cuab ntxaij), zog, high-lub zog bolts, thiab tsheb kis tau.
4.Qhov dab tsi yog cov khoom ntawm 20crmnti (cov hlau carburizing) puag ncig?
Lub zog thiab tawv: muaj alloy hais xws li CR, MN, thiab ti. Tom qab carburizing thiab quenching, lub hardness yog siab (hrc 58-62}}}}}}
Kev Kho Cua Sov: Tus txheej txheem carburizing tuaj yeem tsim lub siab-results woldness-resistant txheej ntawm qhov chaw uas tsim nyog rau qhov chaw uas tsis muaj kev sib txhuam thiab cov txiaj ntsig thiab cov tsho sib tw thiab cov tsho sib tw).
Corrosion Kuj: cov corrosion tsis kam ntawm cov khoom siv muaj dav. Tom qab galvanizing, nws yog siv nyob rau hauv composite scararios uas yuav tsum tau hnav tsis kam thiab corrosion tsis kam (xws li kev ua liaj ua teb
Daim Ntawv Thov Kev Lom Zem: Tsheb Gearbox Zog, Tsheb Laij Teb sib kis tau, thiab Engineeringering Qhov Chaw-Resistant ntu.
5.Qhov yog qhov ua tau zoo ntawm GCR15 (cov kabmob steel) puag ncig?
Lub zog thiab tawv: Cov ntsiab lus carbon yog txog 1. {}}}}}}}}}} {}
Cov Khoom Tshwj Xeeb: Feem ntau yog siv rau kev tsim cov ntaubning rolling dov bearings, thiab tseem tuaj yeem siv raws li high-precision hnav-resistant seem-resistant seem (xws li cov ntsia hlau thiab cov kev qhia kev sib tw). Tom qab galvanizing, nws tuaj yeem tiv thaiv cov kabmob los ntawm kev xeb hauv cov chaw noo noo.
Daim ntawv thov kev xaiv: Cov kabmob chais, ib ncig, precision ntsuas cov cuab yeej, hnav-resistant pwm.
