Vim li cas thiaj xaiv R65 rail profile?

Xaiv qhovR65 rail profileyog qhov kev txiav txim siab zoo rau kev sib txuas ntawm kev tsheb ciav hlau uas yuav tsum muaj siab - lub zog, hnyav- lub hauv paus kev ua haujlwm tau zoo rau lub nra hnyav hnyav thiab huab cua ua haujlwm hnyav. Raws li lub hauv paus txheej txheem ntawm Lavxias teb sab GOST R 51685 specification, qhov no 65 kg / m hnyav rail nta ib tug meej loj ntawm 64.88 kilograms ib meter (64.88 kg / m). Nws sib npaug cov ntaub ntawv ceev nrog geometric efficiency, tso cai rau siab -freight corridors thiab siab - ntim cov neeg caij tsheb mainlines kom tswj tau tshwj xeeb cov qauv rigidity, txo cov khiav geometry degradation, thiab ncua kev txij nkawm nyob rau ntau xyoo ntawm kev nruam cyclic loading.

Txhawm rau kom ua tiav ntev - lub sij hawm taug qab kev nyab xeeb thiab txo qis kev siv tshuab siv tshuab, xaiv qhov profile no muab cov txiaj ntsig tseem ceeb hauv engineering:

• High Structural Moment ntawm Inertia:Lub 180 hli tag nrho qhov siab muab kev tiv thaiv zoo heev tiv thaiv ntsug dabtsi yog khoov, tiv thaiv kev khiav ntau dhau ntawm qhov hnyav dov.

• Thick, Low -Stress Web Design:Engineered nrog 18 hli nruab nrab lub vev xaib, qhov profile muaj kev tiv thaiv zoo tiv thaiv lub zog ntawm sab nraud deformation thiab longitudinal buckling los ntawm khaus raws caij nyoog thermal expansion.

• Optimized Log-rau-Rail Contact Geometry:Lub taub hau dav ntawm 75 mm yog contoured los faib cov log hauv cheeb tsam sib npaug sib npaug, ua rau qeeb qeeb ntawm kev sib cuag qaug zog thiab sab - hnav ntawm cov kab nkhaus.

GNEE RAILSiv cov txheej txheem siab tshaj plaws dov hla dhau thiab kev tswj xyuas hauv online ntsug txias kom xa R65 ntu uas ua rau pom qhov tshwj xeeb ncaj thiab tsis muaj qhov tsis zoo ntawm cov hlau tsis sib xws. Peb cov kab ntau lawm ua ke tag nrho - lub cev electromagnetic tshuaj ntsuam xyuas nrog automated laser dimensional verification kom paub meej tias txhua qhov ntev txaus siab raws li kev cai thoob ntiaj teb nruj. Los ntawm kev muab cov ntaub ntawv qhia ntxaws ntxaws, daim ntawv pov thawj cov khoom siv hluav taws xob tag nrho, thiab cov khoom siv xeb tuaj yeem ua rau xeb- tiv thaiv kev ntim khoom tsim los rau cov khoom thauj hauv hiav txwv hnyav, peb muab siab - cov kev ua tau zoo ntawm cov khoom lag luam uas ua kom cov kev sib txuas thoob ntiaj teb muaj kev nyab xeeb, ruaj khov, thiab ua tau zoo rau ntau xyoo.

Qhov zoo ntawm qhov zoo ntawm R65 rail profile

Cov qauv kev ua tau zoo ntawm GOST-tus qauv R65 (P65) rail profile yog qhov tshwm sim ncaj qha ntawm nws tus ntoo khaub lig-sectional geometry. Los ntawm kev faib nws qhov hnyav 64.72 kg / m rau hauv qhov tshwj xeeb, qhov zoo tshaj plaws qhov ntev (180 hli qhov siab, 150 hli puag, thiab 75 hli lub taub hau), qhov profile ua tiav cov khoom siv zoo uas sib dua lossis tsawg dua tshwj xeeb tsis tuaj yeem rov ua dua.

Specifications ntawm P65 Rail:

Qhov zoo ntawm qhov zoo ntawm R65 profile suav nrog:

High Profilic Qhov siab (180 mm) rau Bending Stiffness

Qhov siab ntsug ntawm txoj kab tsheb ciav hlau yog ib qho tseem ceeb tshaj plaws uas txiav txim siab nws qhov kev tiv thaiv rau kev khoov hauv qab load, raws li qhov tawv tawv exponentially nrog qhov siab.

• Maximizing Vertical Moment of Inertia (Ix ≈3540 cm^4): Sawv ntawm 180 hli, R65 tso ib feem loj ntawm nws cov hlau deb ntawm nws qhov nruab nrab axis. Qhov no minimizes elastic ntsug deflection thaum raug rau hnyav dov Tshuag.

• Kev tiv thaiv substructure: Los ntawm kev tiv thaiv deflection, lub siab profile tiv thaiv txoj kev tsheb ciav hlau los ntawm kev tsim "nthwv dej" sib sib zog nqus ua ntej ntawm cov log tsheb. Qhov no txo ​​cov neeg kho tshuab twj tso kua mis rau ntawm lub txaj ballast, khaws cia cov duab geometry thiab txuas ntxiv tamping lub sijhawm.

Wide Footprint (150 mm Base Width) rau Lateral Stability

Lub hauv paus dav ntawm R65 profile ua haujlwm raws li cov qauv thauj tog rau nkoj, tseem ceeb heev rau kev tuav cov tsheb ciav hlau siab -tonnage thiab siab - nrawm nrawm.

• Overturning Resistance: Siab- qag- thauj cov tsheb ciav hlau thauj khoom siv lub zog loj heev (Y- quab yuam) ntawm qhov nkhaus. Qhov dav ntawm 150 hli muab lub cev dav dav ntawm caj npab uas tiv thaiv cov tilting lub sijhawm, tiv thaiv kev tsheb ciav hlau.

• Load Distribution on Sleepers: Lub hauv paus dav tsub kom qhov chaw sib chwv thaj tsam ntawm txoj kev tsheb ciav hlau thiab khi phaj lossis pw tsaug zog. Qhov no txo ​​qis cov kev ntxhov siab hauv zos (N / mm²), tiv thaiv cov hlau los ntawm kev txiav rau hauv pob zeb lossis ntoo pw thiab txo qis hnav ntawm elastic fastening clips.

Sib sib zog nqus, dav taub hau (75 hli dav) rau Optimized tiv tauj thiab hnav

Lub taub hau qhov ntev yog tsim los kom sib npaug ntawm cov tsheb kho tsheb tam sim nrog ntev - lub neej khoom vaj khoom tsev.

• Txo kev sib cuag: Qhov dav 75 hli, ua ke nrog ntau qhov - vojvoog saum npoo av (R300mm - R80mm - R15mm), ua nruj me ntsis rau cov qauv tsheb ciav hlau log profiles. Qhov no ua rau lub log loj tshaj plaws -rail contact patch, txo kev sib cuag kev ntxhov siab thiab ncua sij hawm qhov pib ntawm dov kev sib cuag qaug zog (RCF) thiab shelling.

• Loj Loj Loj Loj Loj: Qhov tob ntsug ntawm lub taub hau haum rau cov khoom siv poob ntau heev. R65 rails tuaj yeem txhawb nqa qhov tseem ceeb ntsug thiab sab sab - hnav ua ntej tsoo cov txheej txheem kev nyab xeeb txwv, muab cov npoo loj rau kev rov ua dua profile sib tsoo thiab txij nkawm.

Robust 18 mm Web nrog Generous Fillet Radii

Lub vev xaib ua haujlwm raws li kem hloov thauj khoom los ntawm lub taub hau mus rau hauv paus, ua rau nws qhov ntev yog qhov tseem ceeb rau kev tiv thaiv kev puas tsuaj ntawm cov txheej txheem qaug zog.

• Web Buckling Resistance: Lub thickness 18 hli muab qhov tsim nyog tus ntoo khaub lig-sectional cheeb tsam kom tiv taus siab ntsug shear rog thiab dynamic cuam tshuam yam tsis muaj buckling los yog twisting.

• Stress Concentration Mitigation: Cov kev hloov ntawm lub vev xaib mus rau lub taub hau thiab lub hauv paus feature loj, du fillet radii. Kev tshem tawm cov kaum sab hauv kom paub meej tias cov kev ntxhov siab muaj zog sib npaug sib npaug, tiv thaiv kev tsim cov kab nrib pleb ntev nyob ib ncig ntawm lub qhov taub ntses ntses los yog siab - thaj tsam kev ntxhov siab.

FAQ

• Vim li cas R65 rail tsim xaiv 18 hli web thickness tshaj lwm txoj kev nyias nyias?

Lub 18 hli nruab nrab lub vev xaib muab qhov tshwj xeeb tiv thaiv tawm tsam sab nraud shearing rog. Qhov no ntxiv thickness ua rau cov qauv kev ruaj ntseg tiv thaiv kev tawg nyob ze ntawm qhov sib koom bolt qhov nyob rau hauv qhov hnyav longitudinal thermal load stresses.

• Yuav ua li cas xaiv ib tug 150 hli puag flange dav txo cov nqi kho vaj tse?

Qhov dav 150 mm hneev taw nthuav dav lub log loj loj hla thaj tsam kab rov tav loj dua. Qhov kev txo qis qis no tiv thaiv kev sib koom ua ke ntawm kev sib tsoo thiab khaws kev ncaj ncees ntawm lub txaj hauv qab ballast.

• Lub R65 hnyav railway rail yuav siv tau nyob rau hauv Continuous Welded Rail (CWR) lem?

Yog lawm, metallurgical muaj pes tsawg leeg ntawm hwm GOST tus qauv kev tsheb nqaj hlau R65 kev xaiv muaj qhov zoo tshaj plaws weldability. Qhov no tso cai rau cov qauv ntev kom seamless koom rau hauv mais ntawm txoj kev siv high -efficiency automated flash-tooj vuam tshuab.

• Dab tsi yog qhov kev ua neej nyob nce ntxiv thaum xaiv lub taub hau -hardened R65 railway rails?

Lub taub hau- hardening muab qhov sib sib zog nqus, tempered pearlitic hnav tsam (311–401 HBW) ntawm qhov chaw khiav. Qhov kev kho cua sov tshwj xeeb no tuaj yeem ua ob lossis peb npaug ntawm kev pabcuam lub neej ntawm qhov siab - coj nkhaus lem piv rau cov uas tsis yog- cua sov- kho qhov sib txawv.

• Puas yog GOST P51685 tus qauv kev tsheb ciav hlau sib haum nrog cov qauv North American dov cov log tsheb?

Yog lawm, 75 hli lub taub hau dav thiab optimized sab saum toj curvature muaj kev nyab xeeb raws li tus qauv thoob ntiaj teb log profiles, muab tag nrho cov kev ntsuas kev teeb tsa raug kho kom haum rau lub tsheb specifications.

• Dab tsi tshwj xeeb packing txoj kev siv kom ruaj ntseg ntev R65 rail taug kev xa khoom ntawm hiav txwv?

Rails yog txheej ruaj ntseg nyob rau hauv cov khoom sib cais los ntawm kev tiv thaiv ntoo dunnage strips thiab khi nrog hnyav hlau strapping. Ib qho tshuaj tiv thaiv - xeb dej hiav txwv txheej yog siv rau cov hlau liab qab los tiv thaiv cov dej qab ntsev atmospheric oxidation thaum caij tsheb npav.
