Dab tsi yog cov khoom siv feem ntau siv rau A100 Crane Rail?
A100 crane rail(DIN 536 tus qauv) feem ntau yog tsim los siv cov qib siab -lub zog carbon-manganese steel qib tsim los tiv thaiv cov khoom hnyav thiab hnav hauv ib puag ncig kev lag luam.
1. Qib 900 / 900A (Cov Qauv Kev Lag Luam Feem Ntau)
Yog tias koj xaj A100 txoj kev tsheb ciav hlau yam tsis tau hais txog qhov hnyav tshaj - lub luag haujlwm yuav tsum tau ua, nws feem ntau yuav muab rau hauv Qib 900 (feem ntau yog 900A lossis R260). Qhov no yog qhov tsis muaj pov thawj "ua haujlwm" qib rau kev lag luam crane.
- Tensile zog: Yam tsawg kawg 880-900 N / mm² (MPa)
- Hardness: ~ 260 ~ 280 HBW (Brinell Hardness)
- Muaj pes tsawg leeg: Cov pa roj carbon ntau (kwv yees . 0.60 - 0.80%) thiab siab manganese (kwv yees . 0.80 - 1.30%), uas muab cov tawv tawv zoo heev.
- Vim li cas nws thiaj li: Nws muaj qhov sib npaug zoo meej. Nws yog ib qho nyuaj txaus los tiv thaiv qhov hnav thiab flattening tshwm sim los ntawm hnyav kev lag luam cranes, tab sis nws yooj yim dua rau txiav, xyaum, thiab weld dua qib siab dua.
- Daim Ntawv Thov: Txheem sab hauv tsev Hoobkas nyiaj siv ua haujlwm cranes, shipyards, thiab cov chaw tsim khoom hnyav.

2. Qib 1100 / 1080 (Lub Hnyav-Txoj Cai Ua Haujlwm)
Raws li tau tsim, qhov no yog mus- rau qib txheem rau qhov chaw huab cua. Nws tau nquag thov raws li European lub npe zoo li R320Cr.
- Tensile zog: 1080 N / mm² (MPa)
- Hardness: ~ 300 ~ 320 HBW
- Muaj pes tsawg leeg: Cov pa roj carbon ntau, alloyed nrog Chromium (Cr). Cov chromium ho txhawb qhov sib sib zog nqus- hardening thiab tsis kam rau abrasive hnav.
- Kev lag luam tawm -tawm: Vim muaj cov pa roj carbon ntau thiab cov ntsiab lus chromium, nws muaj qhov cuam tshuam rau hydrogen tawg thaum vuam. Nws yuav tsum nruj ua ntej- cua sov, cov txheej txheem vuam tshwj xeeb (xws li Thermite vuam), thiab ua kom txias qeeb.
- Cov ntawv thov raug: Siab- qhov chaw nres nkoj zaus, Nkoj- mus rau -Shore (STS) thawv cranes, steel mills, thiab automated 24/7 hnyav-cov haujlwm retrieval systems.
3. Qib 700 / 690 (Lub Lighter-Txoj Cai Ua Haujlwm)
Raws li tus qauv DIN 536, Qib 700 yog qhov nkag - theem pib. Txawm li cas los xij, vim tias A100 txoj kev tsheb ciav hlau tau tsim los rau kev thauj khoom loj, Qib 700 tsis tshua siv rau qhov tshwj xeeb profile niaj hnub no, txawm tias nws tseem muaj dav.
- Tensile zog:Yam tsawg kawg nkaus 690-710 N / mm² (MPa)
- Hardness:~ 200-220 HBW
- Vim li cas nws tsis tshua muaj rau A100:Yog tias lub chaw siv A100 txoj kev tsheb ciav hlau, lawv feem ntau muaj cov khoom hnyav txaus los ua kom pom zoo rau qib 900. Kev siv cov hlau softer rau ntawm txoj kev tsheb loj loj tuaj yeem ua rau lub taub hau ntxov ntxov.
- Cov ntawv thov raug:Cranes nrog lub voj voog qis heev, kev saib xyuas cranes, lossis lem qhov yooj yim ntawm cov qauv arc vuam yog qhov tseem ceeb tshaj plaws ntawm kev ua neej ntev.
4. Premium Head-Hardened (HH) Qib
Cov rail mills thoob ntiaj teb loj (xws li GNEE RAIL) muab cov qhab nia tsim nyog uas tshaj li tus qauv DIN rau A100 rails.
- Common Designations:340 HH, CR105, lossis R340.
- Yam ntxwv:Cov no pib nrog qib siab - tshuaj lom neeg muaj pes tsawg leeg (zoo ib yam li Qib 1100) tab sis tau txais cov cua sov induction- kev kho tshwj xeeb siv rau sab saum toj thiab sab ntawm lub taub hau tsheb ciav hlau.
- Qhov tshwm sim:Lub taub hau ua tiav qhov hnyav ntawm 340 txog 390 HBW los tiv thaiv kev sib txhuam ntawm lub log, thaum lub hauv paus thiab lub vev xaib tseem softer (ntau ductile) kom nqus tau cov kev poob siab thiab tiv thaiv cov tsheb ciav hlau los ntawm kev sib tsoo hauv qab flexing.
Yuav ua li cas xaiv cov khoom siv hlau tsim nyog rau cov kab tsheb ciav hlau?
Xaiv cov khoom siv hlau uas tsim nyog rau qib kev tsheb ciav hlau yuav tsum muaj qhov sib npaug ntawm cov khoom siv kho tshuab-xws li hardness, lub zog, thiab toughness- tawm tsam kev xav tau ntawm kev ua haujlwm, ib puag ncig, thiab cov nqi ntawm lub neej.
Cov Ntsiab Cai Xaiv
- Axle Load thiab Traffic Volume (MGT):High-density freight lines or heavy-haul railways (axle loads >25t) require stronger, harder steel (e.g., >980MPa rau 1180MPa) kom tiv taus cov kev ntxhov siab loj heev.
- Kev khiav hauj lwm ceev:High -cov neeg caij tsheb ceev xav tau cov tsheb ciav hlau nrog lub zog qaug zog thiab nruj metallurgical purity kom muaj kev sib cuag zoo.
- Curve Radius:Tight curves (radius Tsawg dua lossis sib npaug li 1600m) yuav tsum muaj kev hnav siab dua los tiv thaiv kev hnav kom nrawm dua, xav tau siab dua - qib alloys lossis cua sov- kho steels.
- Ib puag ncig:Tsawg heev - cheeb tsam kub yuav tsum tau steels nrog zoo toughness los tiv thaiv brittle fractures, thaum corrosive ib puag ncig xav tau tshwj xeeb alloy compositions.
- Maintenance Strategy:Cov kab uas muaj cov nqi kho mob siab tuaj yeem ua pov thawj tus nqi pib ntau dua ntawm cov cua sov- kho (HT) rails (piv txwv li, R350HT), uas muaj lub neej ntev dua.
FAQ
- Dab tsi yog qhov txawv ntawm R700 thiab R1100 khoom rau A100 ntsia?
R700 yog tus qauv qib nrog lub zog tensile ntawm 690 N / mm², thaum R1100 yog qib siab - tensile qib nrog tsawg kawg yog 1080 N / mm². R1100 muab kev hnav zoo dua qub thiab xav tau rau kev ua haujlwm siab - zaus lossis siab -tonnage crane.
- Puas yog cov tshuaj muaj pes tsawg leeg ntawm A100 rail txawv ntawm cov qauv kev tsheb ciav hlau?
Yog lawm, crane rails zoo li A100 muaj cov pa roj carbon ntau dua thiab manganese ntau dua kom ua tau zoo dua. Qhov no yog vim hais tias lawv yuav tsum tau tiv taus siab dua lub log tsheb thauj khoom piv rau cov khoom sib faib uas pom ntawm cov neeg caij tsheb lossis cov tsheb thauj khoom thauj.
- Qib 900 A100 rail yuav welded rau Qib 1100 rail?
Yog lawm, tab sis nws yuav tsum tau tshwj xeeb vuam consumables thiab nruj pre- cua sov thiab post- cua sov raws tu qauv. Nws feem ntau pom zoo kom khaws cov ntaub ntawv qib zoo ib yam thoob plaws hauv ib qho kev khiav ntawm crane lem kom ntseeg tau tias hnav tsis zoo thiab thermal expansion.
- Puas yog qib steel cuam tshuam rau DIN 536 A100 rail qhov ntev?
Tsis yog, lub cev qhov ntev (100mm lub taub hau, 200mm puag) tseem zoo ib yam thoob plaws txhua qib raws li DIN 536 tus qauv. Qib tsuas yog hloov cov khoom siv kho tshuab thiab cov tshuaj muaj pes tsawg leeg ntawm cov hlau nws tus kheej.
- Qib twg yog qhov zoo tshaj plaws rau cov ntug dej hiav txwv lossis siab -cov av noo ib puag ncig?
Thaum qib feem ntau txhais lub zog, qhov siab - purity chemistry ntawm Qib 1100 feem ntau muaj qhov zoo dua atmospheric corrosion kuj. Txawm li cas los xij, rau qhov chaw huab cua, cov txheej txheem tshwj xeeb lossis kev siv cov khoom siv crane tshwj xeeb raug pom zoo.
GNEE RAILtuav tag nrho - txheej txheem tsim los ntawm refined steel smelting mus rau siab -precision kub- dov, ua kom txhua tus A100 profile ua tau raws li cov qauv nruj tshaj plaws DIN 536 rau metallurgical purity thiab tensile zog. Peb npaj ntau yam ntawm A-series rails nyob rau hauv ntau qib los muab kev ua tiav sai thiab muab kev txhawb nqa kev tshaj lij rau kev xaiv cov khoom siv zoo tshaj plaws rau koj qhov hnyav - lub luag haujlwm infrastructure.Tau qhov project Quotationkom tau txais lub Hoobkas sib tw- tus nqi ncaj qha thiab cov ntaub ntawv qhia ntxaws ntxaws rau koj cov cai tshwj xeeb crane rail.
