Qhov kub {{{0} Muag cov tawv ntoo carbon lub ntsej muag yog qhov kev tsim qauv steel yog rau Choj Raug rau: St37, Q420, Q460, thiab S235J. Tsiag ntawv los ntawm nws l - Tus ntoo khaub lig sib luag, thiab kev ntxhov siab tsis txaus ntseeg, muaj kev ntxhov siab ib puag ncig, thiab cov kev xav tau ntawm cov choj intrresure. Raws li cov khoom siv tseem ceeb hauv kev tsim kho choj, nws ua haujlwm tseem ceeb hauv load-cov kabmob, ua kom muaj kev nyab xeeb, ua kom ruaj khov, thiab kev ruaj ntseg ntawm choj qauv.
Cov Khoom Siv & Qib -} Tshwj xeeb zoo
Txhua tus kab mob steel yog xaiv rau nws cov yam ntxwv ua kev ua haujlwm tshwj xeeb, sib txawv nrog ntau tus choj tsim qauv rau loj baltosing {{0/2 Railway Txuas hniav):
St37 {{- 2: Lub European Txuj Ci (Din en) qis-}}}} Tus Qauv Hlau Nrog Rau Tsawg Tshaj Plaws Muaj Zog Ntawm 370MPA. Renowned rau nws zoo heev ductility (elongation tus nqi ntau dua los yog sib npaug rau tsis muaj peev xwm, nws yog qhov tsim nyog rau cov khoom lag luam lossis cov khoom lag luam uas muaj peev xwm ua tau thiab cov nqi them rau qhov ua tau zoo.
St52: lub siab - muaj zog tsawg {}}}} almoy) nrog tsawg kawg yog 520mpa. Nws muaj cov tensile zoo dua (630-800MPA) thiab kev cuam tshuam tsis kam (txawm hais tias muaj kev txhawb nqa lub tsheb loj ntawm lub tsheb lossis tsheb ciav hlau.
Q420: Tus qauv Suav (GB / T 1591) HSLA qib steel nrog tsawg kawg ntawm 420MPA. Tsim los rau high- Kev Siv Kev Nyab Xeeb, Ua ntej nws cov khoom siv sab nraud
Q460: qhov siab - Lub zog Suav (GB / T 1560MPA thiab Tensile Lub Zog ntawm 550-720MPA. Nws tau muab kev zam tshwj xeeb load {{}} bearing muaj peev xwm nyob rau hauv loj (piv txwv li cov kabmob Trussical) uas yuav tsum tau tiv taus hnyav zoo li qub thiab kev thauj khoom ntev ntev.
S235J: tus qauv European (EN 100) cov hlau qauv hlau nrog tsawg kawg vim muaj lub zog ntawm 235MPA. Pom tau rau nws txoj kev sib tw weldability (suav nrog txhua qhov kev sib tw vuam, nws yog qhov chaw ruaj khov, thiab tsis muaj qhov chaw nyob ntawm qhov chaw Weld tseem ceeb yog qhov tseem ceeb.
Cov Txheej Txheem Zoo Rau Choj Raug
Cov CLASON ARSLING STEEL tus qauv thiab cov khoom siv yog qhov zoo rau tus choj {{}}}}}}}}}}}}}}}} kev siv:
Dynamic load Kuj: txhua qib nthuav qhia kev ua kom zoo tshaj plaws kev ua tau zoo, muaj kev sib tw lossis tsis sib haum xeeb rau kev pabcuam lub neej
Kev sib koom ua yooj yim: Qhov L - Shape profile tso cai nrog lwm cov kev sib dhos choj (piv txwv li girders, thawv girders, qhob pier). Nws lub tiaj ceg ua kom muaj kev ruaj ntseg sib txuas lossis vuam muag, kom muaj zog sib txuas uas faib cov qauv ntawm Choj.
Corrosion Resilience: Rau cov qib nyiam li Q420 thiab ST52, xam cov txheej txheem los sis cov kev tiv thaiv ntsev, thiab cov kev tiv thaiv ntsev rau sab nraum zoov lossis ntug dej hiav txwv ib puag ncig.
Kev ntsuas qhov tseeb: Tsim tawm hauv kev ua raws thoob plaws hauv cov qib European, gb / {5} -
Cov Kev Siv Raug Nyob Hauv Choj Raug
Cov roj av no siv hluav taws xob no yog qhov tseem ceeb rau ntau yam kev kho choj thiab cov theem kev tsim kho:
Choj thav thav duab / Tribes: Q42 thiab ST52 qib ua ke yog cov tswv cuab Truss, muab cov kab ke kab sib tw, muab cov laj thawj Ciam, muab cov laj thawj tseem ceeb} Cov kabmob Arram.
Lub tshuab khiab mis: Q420 thiab qib ST52 thiab ST52
Kev sib txuas nodes: S235J thiab qib st37-qib tau ua haujlwm rau cov phiaj sib txuas, thiab cov pob tawb / welded-weldes cov khoom siv thaum tswj kev sib tw weldability thiab seem raug.
Ntu: St37-2 Qib yog siv rau cov kws ua yeeb yaj kiab, thiab cov lus qhia kev nyab xeeb thiab kev ua haujlwm yam tsis muaj kev cuam tshuam rau cov qauv kev ntseeg siab.
Kev lees paub zoo rau choj -}} qib kawm ua tau
Kom tau raws li qhov kev nyab xeeb nruj thiab ruaj khov ntawm choj tsim, txhua pob ntawm carbon lub cav hlau undergoes nyuaj tswj:
Kev Kuaj Txhua Yam: Muaj lub zog tensile, tawm los ntawm cov neeg kub ntxhov (ntawm tsawg} Cov kab mob hnyav (ntawm kev ua kom nruj
Tsis - Kev sim tshuaj ntsuam (piv txwv li, kev sib nqus, kom muaj qhov tsis xws luag, kom pom tseeb} cov khoom pub dawb yog muab.
Tshuaj lom neeg tshuaj ntsuam: Kev tsom xam specoscocopic qhia tau cov ntsiab lus tseem ceeb (piv txwv li, n/}}
Ntawv pov thawj & traceabilility: txhua qhov kev xa khoom nrog cov ntaub ntawv xeem (piv txwv li cov lus pov thawj uas ua tiav rau cov khoom lag luam tiav (piv txwv li, Aashto, Eurocode 3).
