Dab tsi yog qhov zoo ntawm kev siv Q235B los tsim Steel Rail?
Jan 20, 2026
Hlau railsyog cov pob txha pob txha ntawm kev lag luam kev thauj mus los, crane lem, thiab warehouse logistics kab. Tsim los coj cov log thiab txhawb nqa cov khoom hnyav, siab - cov tsheb ciav hlau zoo yuav tsum muaj kev sib raug zoo thiab tiv taus hnav lub sijhawm. Lawv qhov kev ua tau zoo nyob ntawm qhov tsis tsuas yog nyob ntawm geometry tab sis kuj nyob ntawm qib steel siv, uas cuam tshuam ncaj qha rau kev ua haujlwm ntev, kev nyab xeeb, thiab kev txhim kho kev ua haujlwm.
Dab tsi yog qhov zoo ntawm kev siv Q235B los tsim Steel Rail?
Rau ntau daim ntawv thov kev lag luam, Q235B steel tau dhau los ua qhov kev xaiv zoo tshaj plaws rau kev tsim steel hlau. Nws kev sib xyaw ua ke ntawm cov khoom siv dag zog, ductility, thiab weldability ua rau nws haum rau lub teeb rau nruab nrab - txoj haujlwm rails hauv cov chaw tsim khoom, chaw nres nkoj, thiab cov kab thauj mus ib ntus.
Q235B steel muaj ntau yam khoom siv thiab kev ua haujlwm zoo uas ua rau nws zoo tagnrho rau kev tsim tsheb ciav hlau:
- Balanced Strength thiab Ductility:Nrog lub zog tawm los ntawm Ntau dua lossis sib npaug ntawm 235 MPa thiab lub zog tensile ntawm 370-500 MPa, Q235B rails tuaj yeem tuav cov haujlwm ua haujlwm thaum nqus cov kev poob siab thiab kev tsis sib haum me me.
- Zoo Weldability:Cov ntsiab lus tsis tshua muaj carbon (0.12–0.22%) tso cai rau kev sib tsoo rau cov pob qij txha, cov phaj hauv qab, thiab cov khoom sib dhos.
- Impact Resistance:Charpy V-kev ntsuas qhov ntsuas ntawm +20℃kom ntseeg tau tias Q235B rails tuaj yeem tiv taus kev ntxhov siab tam sim ntawd, uas yog qhov tseem ceeb rau crane rails thiab siab - tsheb ciav hlau kev lag luam.
| Khoom | Q235B | Chav tsev | Cov txiaj ntsig rau Rails |
|---|---|---|---|
| Yield zog | Ntau dua lossis sib npaug rau 235 | MPa | Txhawb kev ua haujlwm loads yam tsis tas yuav deformation |
| Tensile zog | 370–500 | MPa | Withstands ncov siab |
| Elongation | Ntau dua lossis sib npaug li 26 | % | Absorbs dabtsi yog khoov thiab shocks |
| Hardness | 38–47 | HB | Muab kev hnav tsis kam |
| Cov ntsiab lus carbon | 0.12–0.22 | % | Txhim kho weldability thiab ductility |
Yam Rail Standards Q235B tuaj yeem tsim nyob rau hauv?
Q235B steel tuaj yeem dov rau hauv ntau yam kev tsheb ciav hlau thoob ntiaj teb, ua rau nws muaj ntau yam rau cov haujlwm sib txawv:
- GB/T 11264-2012:22kg uathiab 43kg rails rau warehouse thiab lub teeb crane lem
- JIS E1103-91: 15kg thiab 22kg rails rau Hoobkas crane systems
- DIN 536-70: 50kg rails rau nruab nrab-lub luag haujlwm kev siv
- ASTM A1 / A1M: 60lb rails rau North American kev lag luam lem
| Txuj | Hom Rail | Qhov hnyav (kg / m) | Hom kev siv |
|---|---|---|---|
| GB/T 11264 | 22kg ua | 22.3 | Sab hauv tsev warehouse & teeb crane rails |
| GB/T 11264 | 43kg ua | 43.0 | Me me mus rau nruab nrab crane lem |
| JIS E1103 | 15kg ua | 15.0 | Factory gantry crane ntsia |
| TIAB SA 536 | 50kg ua | 50.0 | Medium industrial rails |
| ASTM A1 | 60 lb | 29.7 | Lub teeb Industrial Track (NA) |
Yuav Ua Li Cas Q235B Rails Piv rau Lwm Cov Qib Hlau?
Piv nrog rau siab dua -carbon lossis European S275JR steels, Q235B muaj:
- Ntau dua ductility, txo qhov kev pheej hmoo ntawm nkig tawg nyob rau hauv lub teeb thiab nruab nrab - lub luag hauj lwm rails.
- Yooj yim ntawm fabrication, tso cai rau ua ntej -drilled qhov, nkhaus ntsia, thiab vuam yam tsis muaj cov txheej txheem tshwj xeeb.
- Kev sib npaug zoo ntawm tus nqi thiab kev ua tau zoo, ua rau nws zoo tagnrho rau warehouses, ports, thiab ib ntus kev lag luam kab.
| Kev sib piv | Q235B | S275 JR | Sau ntawv |
|---|---|---|---|
| Yield zog | Ntau dua lossis sib npaug li 235 MPa | Ntau dua lossis sib npaug li 275 MPa | S275JR muaj zog dua tab sis tsawg dua ductile |
| Elongation | Ntau dua lossis sib npaug li 26% | Ntau dua lossis sib npaug li 20% | Q235B absorbs shocks zoo dua |
| Vuam | Zoo heev | Zoo heev | Ob qho tib si haum rau thaj chaw vuam |
| Daim ntawv thov | Light-medium rails | Medium-heavy rails | Q235B nyiam dua rau kev lag luam sib dua |
Raws li tus kws tshaj lij rail fastener tsum,GNEE RAILtuaj yeem muab cov qauv hlau sib txawv xws li GB, Asmeskas, BS, UIC, DIN, JIS, Australian thiab South Africa uas siv hauv kev tsheb ciav hlau, cranes thiab thee mining.
