A hlau railyog qhov tseeb- dov steel profile uas tsim kom muaj qhov chaw khiav thiab cov txheej txheem txuas ntxiv ntawm kev khiav, ua kom cov tsheb nyob twj ywm kom zoo thaum tiv thaiv kev khoov, shear, thiab nto hnav. Nws cov geometry thiab metallurgy raug xaiv kom sib npaug ntawm lub zog thiab ua haujlwm nyob rau hauv kev rov ua dua.
GNEE RAILmuaj cov tsheb ciav hlau tsim los rau GB, UIC, DIN536, JIS, AS1085, BS11, thiab AREMA / ASCE cov qauv, suav nrog cov tsheb ciav hlau, tsheb ciav hlau hnyav, thiab crane rail series xws li QU thiab DIN A-profiles, ua ke nrog cov kev pabcuam rau kev kho kom ntev, kev npaj vuam, thiab cov khoom siv sib txuam.
Dab tsi yog qhov ntev ntawm ASCE 25 rail?
ASCE 25 nta ib qho sib luag 'I-beam' (tee) profile, tsim rau lub teeb- daim ntawv thov kev tsheb nqaj hlau. Nws qhov ntev yog raws li nram no: lub taub hau dav ntawm 38.1 hli, qhov siab ntawm 69.85 hli, lub hauv paus dav ntawm 69.85 hli, thiab lub web thickness ntawm 7.54 hli. Qhov hnyav theoretical yog kwv yees li 12.4 kg ib 'meter'. Qhov kev tsim qauv hnyav no ua rau yooj yim rau kev thauj mus los thiab kev teeb tsa, ua rau nws tshwj xeeb tshaj yog haum rau nruab nrab - txuas txuas thiab kev teeb tsa ib ntus.
ASCE 25 rails yog hom kev tsheb ciav hlau sib sib zog nqus hauv ASCE cov tsheb ciav hlau, hnyav 25 phaus ib yard (25lb / yd). Lawv feem ntau yog siv nyob rau hauv qis- daim ntawv thov ceev xws li lub teeb tsheb ciav hlau thauj mus los thiab kev lag luam lem.
Qhov zoo ntawm Peb ASCE25 Rail
- Tus nqi-Kev Ua tau zoo: Sib npaug kev siv nyiaj txiag nrog cov khoom siv kho tshuab txhim khu kev qha, muab tus nqi-txuag lwm txoj hauv kev hnyav.
- Customizable Specifications: Raws li qhov xav tau ntawm qhov project nrog qhov hloov tau ntev (12m - 25m +), qib khoom siv, thiab kev hloov kho qhov ntev kom haum haum.
- Kev xaiv cov khoom siv ruaj khov: Muaj nyob rau hauv Q235B, 55Q, thiab U71Mn steels, kom ntseeg tau tias kev hloov pauv mus rau qhov sib txawv load peev xwm, hnav tsis kam, thiab ib puag ncig xav tau.

- Kev Txhim Kho & Kev Kho Kom Yooj Yim: Lub teeb tsim teeb txo qis kev teeb tsa kev ua haujlwm thiab cov khoom siv, thaum cov ntaub ntawv muaj zog txo kom ntev -cov kev xav tau kev tu ncua sij hawm.
Dab tsi yog qhov txawv ntawm ASCE 25 rail thiab GB 22kg rail?
Qhov txawv tseem ceeb yog lawvqhov hnyav, tus qauv, thiab daim ntawv thov raug: ASCE 25 (25 lb / yd, kwv yees li . 12.4 kg / m) yog ib qho kev sib tw Asmeskas tus qauv tsheb ciav hlau siv rau lub teeb heev- lub luag haujlwm xav tau, thaum GB 22kg rail (22 kg / m) yog Suav tus qauv tsheb ciav hlau hnyav dua me ntsis, tab sis tseem lub teeb - lub luag haujlwm kev lag luam, mining, thiab kev ruaj khov siv ob qho tib si, tab sis muaj peev xwm siv tau ib ntus.
