Dab tsi yog cov yam ntxwv ntawm GOST R65 rail profile?

GOST - tus qauvR65 (P65) rail profileyog lub hauv paus tsim engineering rau hnyav- thauj khoom thauj txoj hauv kev, siab - cov neeg caij tsheb sib txuas, thiab kev thauj mus los hauv kev lag luam ua haujlwm hauv cov khoom hnyav hnyav. Kev tswj hwm los ntawm cov qauv xws li GOST 51685, nws cov yam ntxwv yog txhais los ntawm hnyav linear mass, robust cross-sectional geometry, thiab tshwj xeeb metallurgical design.

Cov yam ntxwv tseem ceeb ntawm R65 rail profile yog tsim nyob rau hauv plaub pawg thawj coj:

Geometric & Dimensional yam ntxwv

Lub cev proportions ntawm R65 profile yog xam los txhim kho qhov kev faib tawm ntawm siab qag loads (25 mus rau 35 tonnes) nqis los ntawm txoj kev taug kev.

• Tag nrho qhov siab (180 mm):Muab qhov siab profile qhov tob, ua kom muaj zog ntsug thiab txo qis elastic deflection nthwv dej thaum cov tsheb ciav hlau hnyav dhau.

• Lub hauv paus dav (150 mm):Tsim ib qho chaw ruaj khov tshwj xeeb uas txo qis hauv cheeb tsam ntawm cov neeg pw tsaug zog thiab tiv thaiv kev tsheb ciav hlau tilting lossis rollover nyob rau hauv cov rog sab nraud.

• Lub taub hau dav (75 mm):Features muaj ntau- radius sab saum toj profile (R300 mm - R80mm - R15mm) tsim los ua kom lub log loj tshaj -rail contact patch, txo kev sib cuag.

• Web Thickness (18 hli):Ib kab ntsug tuab nrog dav dav fillet radii hloov los tiv thaiv ntsug buckling thiab tiv thaiv longitudinal cracking.

Lub cev & pawg yam ntxwv

Lub cev loj ua raws li lub dampening thauj tog rau nkoj rau tag nrho cov qauv khiav, ncaj qha cuam tshuam rau longitudinal thiab lateral stability.

• Qhov hnyav Theoretical:64.72 kg/m (raws li nominal cross-sectional cheeb tsam ntawm ≈ 82.45 cm² thiab steel ntom ntawm 7850 kg/m³).

• Commercial/Delivery Nyhav:Feem ntau suav ntawm 64.88 kg / m rau tus account rau rolling mill tolerances thiab manufacturing allowances.

• Lub Sij Hawm Ntawm Inertia (Ix≈3540cm^4):Muab cov nqaj rigidity zoo nyob rau hauv kab rov tav axis, uas khaws cov kev sib tw khiav thiab txo cov tsheb ciav hlau dov tsis kam.

Cov yam ntxwv ua haujlwm & Layout

Qhov profile qhov ntev thiab loj dictate nws cov kev ua haujlwm tsis zoo hauv kev teeb tsa thiab kev tsim qauv.

• CWR (Nruam Welded Rail) Compatibility: Tus ntoo khaub lig ntau heev- ntu loj muab qhov tsim nyog tiv thaiv qhov ntev ntev thermal quab yuam, tiv thaiv kev khiav buckling thaum lub sij hawm siab - kub viav vias.

• Extended Wear Headroom: Kev teeb tsa lub taub hau sib sib zog nqus muab qhov ntim dav ntawm cov hlau txiab, tso cai rau kev siv ntau qhov ntsug thiab sab nraud txwv thiab ntau qhov sib tsoo / rov ua dua tshiab ua ntej so haujlwm.

• Standard Delivery Lengths: Feem ntau muab rau hauv tus qauv 12.50 m thiab 25.00 m ntev rau kev sib koom ua ke lossis hloov layouts, thiab 100.00 m monoliths rau seamless, siab - ceev mainlines.

Qhov twg siv tau RAIL R65?

RAIL R65 (tseem hu ua P65) yog qhov hnyav - txoj haujlwm railway profile ua rau Lavxias GOST cov qauv. Nws feem ntau yog siv rau txoj kev tsheb ciav hlau loj, siab - kab nrawm, hnyav- thauj khoom thauj khoom thauj, thiab kev tsheb ciav hlau kev lag luam vim nws cov khoom hnyav- cov kabmob muaj peev xwm thiab tshwj xeeb hnav tsis kam.

• Heavy-Haul & Freight Networks:Nws txhawb nqa cov tsheb ciav hlau thauj khoom hnyav (25-30 tonnes ib lub qag) rau kev tsuas, kev thauj mus los ntau, thiab cov peev txheej kev lag luam.

• High -Speed ​​Rail:Thaum ua ke nrog kev sib txuas txuas txuas ntxiv (CWR) thiab cov pob zeb pw tsaug zog, R65 tuaj yeem tswj cov neeg caij tsheb ciav hlau ceev ntawm 200-250 km / h.

• Industrial & Chaw nres nkoj Railways:Nws muab cov qauv kev ruaj ntseg xav tau rau gantry cranes, steel mills, thiab multimodal transshipment cheeb tsam.

Cov lus nug nquag

• Dab tsi yog qhov tso cai hnyav rau tus qauv GOST R65 steel rail thaum dov?

Raws li Lavxias teb sab GOST P51685 tus qauv, qhov pom tau qhov hnyav sib txawv ntawm ib kab meter yog nruj nruj nyob rau hauv qhov nqaim feem pua. Qhov kev tswj hwm kev tsim khoom no tau lees paub qhov sib txawv ballast load faib thiab kwv yees tus cwj pwm taug qab.

• Puas yog kev cai bolt qhov tau drilled rau hauv P65 rail khiav ntawm lub Hoobkas?

Yog lawm, qhov kawg tuaj yeem muab tau los ntawm kev teeb tsa dawb paug rau kev txuas txuas txuas txuas txuas (CWR) los yog ua ntej -machined nrog cov qauv voj voog thiab oval bolt qhov qauv kom haum rau koj qhov kev sib koom ua ke.

• Yuav ua li cas 150 mm puag dav tiv thaiv ntoo thiab pob zeb taug kev pw tsaug zog?

Lub hauv paus phaj dav faib cov log ntsug ntsug hla thaj tsam loj dua kab rov tav. Qhov no minimized av siab hneev taw tiv thaiv lub hauv paus steel los ntawm hnav mus rau hauv pob zeb sib txuas los yog splitting ntoo khiav lug.

• Dab tsi yog qhov ntsuas kub qis tshaj plaws rau GOST Standard Rail R65?

Ua tsaug rau lub hom phiaj ntawm vanadium thiab titanium grain micro-alloying, cov hlau tuav tau zoo tshaj cov qauv toughness thiab cuam tshuam tsis kam ntawm ambient kev khiav hauj lwm kub poob qis li -60℃yam tsis muaj kev pheej hmoo ntawm brittle fracturing.

• Cov hnyav no puas yog - lub luag haujlwm railway rails haum rau qeeb -ceev muaj overhead crane khiav?

Yog lawm, vim hais tias ntawm lub tiaj tus, dav hauv paus thiab tuab 75 hli lub taub hau layout, qhov profile no tau hloov kho tsis tu ncua rau siab - muaj peev xwm muaj crane lem uas thauj hnyav heev - lub luag haujlwm tshuab hla cov nroj tsuag.
