Dab tsi yog qhov hnyav ntawm GB lub teeb khiav tsheb ciav hlau?
Qhov hnyav ntawm GB lub teeb khiav tsheb ciav hlau yog txhais los ntawm nws qhov loj ntawm ib lub 'meter', uas ncaj qha cuam tshuam txog kev tsheb nqaj hlau thauj khoom -cov kabmob muaj peev xwm thiab cov ntawv thov tsim nyog. Raws li Suav GB qauv, lub teeb rails yog tsim los rau kev lag luam, mining, chaw nres nkoj thiab ib ntus railway lem, qhov twg qag loads thiab kev khiav hauj lwm ceev yog qis dua nyob rau hauv mainline railways.
GB lub teeb rails tau teev los ntawm qhov hnyav ib 'meter', feem ntau 8 kg / m, 9 kg / m, 12 kg / m, 15 kg / m, 18 kg / m, 22 kg / m, 24 kg / m thiab 30 kg / m, ib GB / T 11264-2012. Qhov tseeb theoretical mass yog me ntsis siab dua tus nqi nominal, piv txwv li 8.42 kg / m rau 8 kg qauv thiab 30.1 kg / m rau 30 kg qauv.

Lub teeb rail piv rau hnyav rail
| Yam khoom | Lub teeb steel rail | Hnyav hlau rail |
|---|---|---|
| Qhov hnyav | 8-30 kg / m | 43 kg/m thiab siab dua, xws li . 50, 60, UIC 60 |
| Daim ntawv thov | Lub teeb rail tsheb thauj mus los, trams, industrial lem, ports, mining | High- txoj kev tsheb ciav hlau ceev, cov kab loj loj, hnyav- lub luag haujlwm thauj khoom |
| Load peev | Nruab nrab mus rau qis, lub teeb -load lossis qis- siv zaus | Siab, tsim rau loj - nplai tshuab |
| Cov ntaub ntawv qib | Q235B, 55Q | U71Mn, 50Mn, R260, R350HT thiab lwm yam siab -lub zog steels |
| Cov qauv zoo sib xws | GB / T 11264 (8-30 kg), JIS, AREMA lub teeb seem | GB 2585 (50/60 kg), UIC 60, EN 13674, AREMA |
| Machineability | Yooj yim rau txiav, xyaum, khoov lossis kho | Machinable tab sis nyuaj, xav tau cov cuab yeej muaj zog dua |
| Kev teeb tsa | Yooj yim thiab hloov tau yooj yim rau luv - lem | Yuav tsum muaj kev sib koom ua ke zoo xws li vuam thiab clamping |
FAQ
Vim li cas qhov hnyav tiag txawv ntawm tus nqi nominal kg/m?
Tus nqi nominal yog ib lub npe sib npaug; qhov theoretical loj yog xam los ntawm qhov tseeb seem cheeb tsam thiab steel ntom, yog li 8 kg / m yog 8.42 kg / m.
Dab tsi yog qhov hnyav tshaj GB tsheb ciav hlau?
30 kg / m seem nrog qhov tseeb loj ntawm 30.1 kg / m yog cov qauv hnyav tshaj plaws nyob rau hauv GB lub teeb rail ntau yam; siab tshaj 30 kg/m rails yog classed raws li hnyav rails.
Tus qauv twg tswj hwm GB lub teeb rail qhov ntev?
GB / T 11264-2012 npog qhov ntev, qhov hnyav thiab kev xav tau ntawm Suav lub teeb rails.
GB lub teeb tsheb ciav hlau puas tuaj yeem siv rau hauv av mining?
Yog lawm, 18 kg / m thiab 22 kg / m seem hauv 55Q lossis U71Mn yog cov kev xaiv zoo tshaj plaws rau kev tsheb ciav hlau hauv av.
Puas yog lub teeb rail hnyav cuam tshuam rau lub kaw lus fastening?
Yog, lub hauv paus dav thiab ntu loj txiav txim siab qhov sib txuam hauv qab phaj, clips, spikes thiab cov ntaub qhwv rau lub kaw lus fastening.
