Txoj kev tsheb ciav hlauyog ib qho tseem ceeb ntawm txoj kev tsheb ciav hlau, thiab nws txoj haujlwm yog coj lub tsheb ciav hlau lub log mus rau pem hauv ntej los ntawm kev tiv thaiv lub zog loj ntawm lub log. Steel rail yuav tsum muab du, ruaj khov thiab nruam dov nto rau lub tsheb ciav hlau dhau lub log. Nyob rau hauv hluav taws xob railway los yog tsis siv neeg thaiv seem, railway khiav kuj yuav siv tau raws li ib tug khiav Circuit Court.
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.

JIS steel qib sib npaug li cas?
JIS steel qib, txhais los ntawm Japanese Industrial Standards (JIS), feem ntau sib npaug ntawm cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab rau qib hauv GB (Tuam Tshoj), EN / DIN (Tebchaws Europe), ASTM (USA), thiab BS (UK) cov qauv, tab sis lawv tsis yog ib txwm 100% zoo tib yam.
JIS steel sib npaug li cas hauv lwm cov qauv?
JIS qib feem ntau sib phim nrog:
- GB (Tuam Tshoj National Standard)
- EN / DIN (European Standard / German Standard)
- ASTM / AISI (American qauv)
- BS (British Standard)
Rausteel rails, sib npaug tsom rauhardness, hnav tsis kam, thiab qaug zog ua haujlwm, tsis yog chemistry xwb.
Hom kev sib npaug sib npaug:
| JIS Rail Qib | GB Rail Qib | EN/UIC Qib | Daim ntawv thov |
|---|---|---|---|
| JIS 50 N | GB 50kg / m | UAS 50 | Lub teeb mainline / metro |
| JIS 60 | GB 60kg / m | UIC 60 (R260/R350HT) | Heavy thauj / siab ceev |
| JIS 30 kg | GB 30kg / m | DIN S30 | Kev lag luam / mining |
| JIS 22 kg | GB 22kg / m | DIN S20 (kev siv zoo sib xws) | Mining / lub teeb thauj |
Txawm hais tias qhov hnyav tuaj yeem sib xws, ntu profile thiab kev kam rau siab tuaj yeem sib txawv, yog li cov tsheb ciav hlau tsis tas yuav hloov pauv yam tsis tau kuaj xyuas cov duab kos thiab cov tshuab kaw.
GNEE RAILcov khoom siv niaj hnubGB, JIS, EN/UIC, BS, DIN, thiab AREMA steel rails, thiab tuaj yeem txheeb xyuas qhov profile sib xws, tshuaj lom neeg muaj pes tsawg leeg, thiab kev ua haujlwm zoo ua ntej hloov lossis sib xyaw- qauv kev teeb tsa.
