Tsib Qhov Ntau Pawg ntawm cov ntsia hlau

Koj puas paub tsib pawg loj ntawm cov tsheb ciav hlau?

Muaj ntau hom kev tsheb ciav hlau. Cia peb mus saib ze zog:

1. Kev faib tawm raws li Rail hnyav:
Hnyav rails: Rails weighing 50kg / m thiab siab dua li 50kg / m, 60kg / m, 75kg / m, thiab lwm yam.
Cov kev tsheb ciav hlau teeb: Cov hlua hnyav qis dua 50kg / m, xws li 38kg / m, 43kg / m, thiab lwm yam.

2. Kev faib tawm raws txoj kev tsheb nqaj hlau hla cov duab:
Symmetrical hla kev muag khoom sib tw: cov kev ntsia ib txwm muaj.
Asymmetric cross-saltal crairs: feem ntau yog siv los ua cov tig xub ntiag, rab rawg lossis ntsia hlau, 60at, 60Tty, thiab lwm yam.

3. Kev faib tawm raws Rail Tshuaj Sib xyaw:
Carbon Rails: dog dig tsawv tsis muaj alloying ntsiab.
MicroalloLoLoLoad: muaj kab alloying ntsiab xws li Vanadium V, Niobium NB, Thallium TI, thiab lwm yam.
Tsawg alloy Rail: EN32 {1}}} crin muaj 0.80% mus rau 1.20% chromium.

4. Kev faib tawm raws li kev xa khoom ntawm kev tsheb nqaj hlau:
Kub-dov Rail: Rail xa tawm hauv lub xeev kub.
Cov Rail Rail: Rail uas tau dhau los ua txheej txheem kev ua kom sov sov, muab faib ua offline kub kev kho thiab kho cua sov.

5. Kev faib tawm raws li qhov tsawg kawg tensile lub zog ntawm kev tsheb nqaj hlau:
780MPA: xws li European En220.
880MPA: Xws li European EN260, EN260MN, Uic900A, Tuam Tshoj U71MN, thiab lwm yam.
980MPA: Xws li Asmeskas arema dog dig Rail, Tuam Tshoj U75V, U77MNCCR kub-dov Rail.
1080MPA: xws li European En320cr alloy Rail, Japanese HH340 online ntawm kev tsheb ciav hlau kub, Tuam Tshoj U78CRV.
1180MPA: xws li Nyij Pooj HHB70 online online-ua kom kub, Europe, EN350LHT Online Rails, Tuam Tshoj U75V Online Dail-Kho Cov Ntsia Kub.
1200 ~ 1300MPA: xws li Tuam Tshoj U78CRV online-kho cov ntsia hlau, thiab lwm yam.

To taub cov kev faib tawm no tuaj yeem pab peb xaiv cov tsheb ciav hlau uas tsim nyog los xyuas kom muaj kev nyab xeeb thiab ruaj khov ntawm txoj kev tsheb nqaj hlau.
