A hlau railyog lub cev ciam teb uas txhais lub tsheb trajectory, tiv thaiv lateral deviation thiab ua kom meej tswj kev txav ntawm ob qho tib si kev thauj mus los thiab cov khoom siv. Nws lub taub hau profile cuam tshuam nrog lub log flange geometry los xyuas kom meej cov kev taw qhia thiab derailment tsis kam, thaum nws ko taw ruaj lub tsheb ciav hlau mus rau cov qauv khiav.
GNEE RAILxa tag nrho -cov ntaub ntawv profile rau kev tsheb ciav hlau, crane, chaw nres nkoj, thiab cov tshuab mining, thiab muab cov kev daws teeb meem fastening, kev vibration - cov ntaub ntawv cais tawm, thiab cov tshuab thauj tog rau nkoj kom ruaj khov kho tsheb nyob rau hauv ntau yam kev ua haujlwm.
Muaj pes tsawg hom rails muaj?
Tsis muaj ib tus naj npawb ntawm cov tsheb ciav hlau, vim cov tsheb ciav hlau raug cais los ntawmdaim ntawv thov, profile (cross-section), qhov hnyav, thiab cov txheej txheem txheem, tab sis nyob rau hauv engineering xyaum lawv feem ntau yog pab pawg ua kePeb pawg tseem ceeb: railway rails, crane rails, thiab tshwj xeeb industrial rails, nrog ntau sub- hom nyob rau hauv txhua qeb kom phim cov load thiab kev khiav hauj lwm sib txawv.
- Thawj qeb thiab loj tshaj plaws yograilway rails rau tsheb ciav hlau ua haujlwm, uas yog siv rau cov neeg caij tsheb, cov kab tsheb thauj mus los, mining railways, thiab industrial sidings. Cov tsheb ciav hlau no feem ntau yog cais los ntawmhnyav ib 'meter' thiab profile geometry, thiab raug tsim nyob rau hauv cov qauv xws liUIC, EN, AREMA/ASCE, BS, JIS, AS, thiab GB. Hauv cov phiaj xwm thoob ntiaj teb, lawv feem ntau muab faib uaLub teeb rails (kwv yees li 8-30 kg / m)rau cov mines, kev cob qhia, thiab luv -kev thauj mus los deb, thiabhnyav rails (li 38-60 kg / m)rau mainline railways thiab hnyav freight. Cov qauv thoob ntiaj teb muaj xws liUIC50, UIC54, UIC60, 50kg, 60kg, 75lb, 115RE, thiab 136RE, tag nrho cov sib txawv ntawm lub taub hau dav, qhov siab, thiab khoov muaj peev xwm kom haum rau qag load, ceev, thiab khiav qauv tsim.

- Qhov thib ob loj qeb yogcrane tsheb, uas yog tsim tshwj xeeb rau cov nyiaj siv ua haujlwm cranes, gantry cranes, thiab rail - cov khoom siv chaw nres nkoj. Cov ntsia hlau no muaj ntau lub log loads ntau dua thiab muaj zog lateral zog dua li cov tsheb ciav hlau, yog li lawv cov ntaub ntawv muaj zog dua thiab muaj zog, nrog cov webs tuab thiab dav dua. Ob qhov kev siv ntau tshaj plaws crane rail systems yogDIN 536 A-series rails (A55, A65, A75, A100, A120)thiabQU Crane Rail (QU70, QU80, QU100, QU120). Cov no tsis tuaj yeem hloov pauv nrog cov qauv kev tsheb ciav hlau, vim tias lub log cranes, lub kaw lus fastening, thiab cov kab hluav taws xob khiav tau tsim los ntawm cov qauv tshwj xeeb no. Nyob rau hauv cov chaw nres nkoj, steel mills, thiab thawv yards, crane rails raug suav hais tias yog ib qho kev qhia tshwj xeeb ntawm kev tsheb ciav hlau vim lawv qhov sib txawv ntawm kev thauj khoom thiab kev saib xyuas.

- Cov qeb thib peb yogtshwj xeeb thiab industrial rails, uas suav nrog grooved rails rau hauv nroog tram systems, tiaj bar rails rau embedded los yog nto -mounted daim ntaub ntawv, thiab customized profiles rau automated warehouses los yog ntau lawm kab. Grooved rails, feem ntau siv nyob rau hauv txoj kev - khiav lub teeb rail systems, cia lub log flange khiav nyob rau hauv ib tug channel kom lub tsheb ciav hlau yuav embedded rau hauv pob zeb los yog pavement. Pav ca bar rails thiab tsis yog - qauv profiles yog siv nyob rau hauv qhov chaw installation yog txwv los yog qhov chaw tshwj xeeb cov kev taw qhia yuav tsum tau, thiab cov no feem ntau yog tsim los rau project- tshwj xeeb kos duab es tsis yog pej xeem railway qauv.
Ntxiv rau qhov profile-raws li kev faib tawm, cov tsheb ciav hlau kuj tau categorized los ntawmsteel qib thiab kev kho cua sov, uas ntxiv multiplies tus naj npawb ntawm cov tswv yim "hom." Piv txwv li, tib UIC60 profile tuaj yeem muab nkag rau hauvR260, R350HT, lossis lwm lub taub hau- cov qib hardened, thiab crane rails tuaj yeem tsim hauvU71Mn, U75V, lossis sib npaug siab -lub zog pearlitic steelsnyob ntawm qhov yuav tsum tau hnav thiab qaug zog. Los ntawm kev xav engineering, hom profile thiab qib steel ua ke txhais cov hom kev tsheb ciav hlau zaum kawg xaiv rau ib qhov project.
