Yuav Ua Li Cas Rail Loj yog txhais
Ib qho kev tsheb ciav hlau tau piav qhia los ntawm peb qhov tsis muaj: qhov ntsuas ntsuas (qhov kev ncua deb ntawm sab hauv ntawm ob lub taub hau tsheb ciav hlau, tus qauv ntawm 1435 mm ntawm feem ntau cov tes hauj lwm), qhov hnyav seem hauv kg / m (los yog lb / yd), thiab qhov profile geometry, uas suav nrog lub taub hau dav, lub hauv paus dav, qhov siab qhov siab thiab lub vev xaib thickness. Lub profile yog tsim los ua ib qho I-beam kom lub taub hau nqa lub log kev nyuaj siab, lub vev xaib tiv thaiv shear, thiab lub hauv paus kis tau cov load rau cov neeg pw tsaug zog. Ob txoj hlua nrog qhov hnyav tib yam tuaj yeem muaj qhov sib txawv, yog li ib txwm qhia meej tus qauv thiab ntu lub npe thaum xaj, piv txwv li UIC60, 115RE lossis 60 kg / m ib GB / T 2585.
Cov Nqe Lus Qhia los ntawm Standard
| Txuj | Tshooj | Hom Qib |
|---|---|---|
| UIC 860 | UIC54 / UIC60 | R260, R350HT |
| TS EN 13674-1 | 49E1 (50 kg / m) / 54E1 (54 kg / m) / 60E1 (60 kg / m) | R200, R260, R350HT, R260Mn, R320Cr, R370CrHT |
| IB 11-1985 | BS80A / BS90A / BS100A | 700, 900A, 900B |
| AREMA | 115 RE/136 TSI | SS, HH, LA, IH |
| ASCE | UAS 60 / ASCE 85 | ua 71mn |
| GB/T 2585-2007 | 50 kg / m / 60 kg / m / 75 kg / m | U71Mn, U75V |
| TB/T 2344-2012 | 50 kg / m / 60 kg / m / 75 kg / m | U71Mn, U75V, U77MnCr, U78CrV |
| GB 11264-1989 | 8-43 kg / m teeb rail | Q235, 50Mn, U71Mn |
Rau cov crane khiav, tiaj tus- hauv qab crane rails ib GB yog xaiv QU70, QU80, QU100 thiab QU120, ib txwm muab hauv U71Mn. European crane rails ua raws DIN 536 nrog profiles A55 rau A120. Vim hais tias lub crane rail nqa lub log nrog lub tiaj tiaj thiab sab flanges, nws lub taub hau geometry txawv ntawm txoj kev tsheb ciav hlau ntawm qhov hnyav sib xws.
Rail Steel Qib thiab Cov Txheej Txheem
Rails yog kub- dov los ntawm siab - carbon steel nrog tswj alloying. Cov qib zoo thiab cov nominal muaj pes tsawg leeg yog: R260 (C 0.67-0.80%, Mn 0.90-1.20%, Si mus txog 0.50%), R350HT (lub taub hau-hardened, C 0.75-0.85%, Mn-1.0. 0.20-0.50%), AREMA Qib 260 (C txog 0.77%), AREMA Qib 350 (microalloyed nrog V los yog Nb), U71Mn (C 0.65-0.77%, Mn 1.10-1.40%) thiab U75V (C 0.67%)-0. Lub taub hau-hardened qib xws li R350HT txhim kho hnav thiab qaug zog tiv thaiv rau cov kab nkhaus thiab cov kab siab. Bainitic rails (C 0.65-0.80%, Mn 1.0-1.4%, nrog rau kev xaiv Cr/Mo/Ni) yog siv nyob rau hauv ib tug ua ke ntawm siab zog thiab weldability yuav tsum tau.
Xaiv qhov raug Rail Loj
Xaiv qhov hnyav seem ntawm lub qag load thiab txhua xyoo tonnage. Lub teeb rails ntawm 8-30 kg/m haum rau kuv lub tsheb, ib ntus sidings thiab me me gantry cranes. Qhov nruab nrab nyob ib ncig ntawm 50-54 kg/m yog siv rau cov kab nruab nrab thiab cov ceg tsheb thauj mus los . 60 kg/m rail yog cov neeg ua haujlwm ntawm cov kab tseem ceeb, cov kab siab ceev thiab metros . 75 kg / m rail yog tshwj tseg rau hnyav-haul corridors nrog qag loads saum 30 t. Txheeb xyuas qhov dav ntawm txoj kab tsheb ciav hlau tawm tsam tus neeg pw tsaug zog, khi phaj thiab fastening system: lub tsheb ciav hlau hnyav dua nrog lub hauv paus dav dua yuav tsum muaj qhov sib txuam, lub xub pwg nyom thiab ntiv taw ntiv taw. Kuj lees paub tus qauv xa khoom, vim tias AREMA 115RE thiab EN 60E1 tsis zoo ib yam txawm tias lawv nqa cov tsheb sib xws.
Ordering Checklist

Cov lus nug nquag
Q: Tus qauv ntsuas ntawm txoj kev tsheb ciav hlau yog dab tsi?
A: Tus qauv ntsuas yog 1435 hli (4 ft 8 1/2 nyob rau hauv), siv li ntawm 60% ntawm lub ntiaj teb txoj kev tsheb ciav hlau. Qhov ntsuas me me ntawm 1000 mm thiab 1067 mm yog tshwm sim ntawm cov kab nruab nrab thiab roob.
Q: 60 kg / m rail txhais li cas?
A: Nws yog qhov hnyav ntawm ib 'meter' ntawm kev tsheb nqaj hlau, txog 121 lb / yd. Qhov tseeb qhov hnyav ib meter ntawm EN 60E1 yog li 60.21 kg. Qhov hnyav ib 'meter' yog txoj kev ceev tshaj plaws los sib piv cov tsheb ciav hlau qhov ntau thiab tsawg ntawm cov qauv.
Q: Qhov txawv ntawm UIC60 thiab AREMA 115RE yog dab tsi?
A: Ob leeg ua haujlwm tseem ceeb - kab tsheb khiav ntawm kwv yees li 60 kg / m chav kawm, tab sis qhov profile qhov ntev sib txawv: UIC60 muaj qhov siab dua nrog lub hauv paus nqaim, thaum 115RE muaj lub hauv paus dav dua thiab sib txawv ntawm lub taub hau geometry. Lawv xav tau cov hlua khi sib txawv, cov ntaub qhwv thiab cov clips, thiab tsis tuaj yeem hloov pauv ntawm tib lub txaj.
Q: Yam kev tsheb ciav hlau twg yuav tsum tau siv rau thaj chaw txias?
A: Rau cov huab cua txias xaiv cov qib nrog lav qis - qhov kub thiab txias, xws li R260 nrog kev tswj kev huv lossis U71Mn nrog kev ntsuas qhov cuam tshuam ntawm -40℃. Lub taub hau-hardened R350HT yog zam ntawm qhov nkhaus nkhaus heev hauv qhov txias txias tshwj tsis yog tias qhov project qhia nws nrog kev sim ntxiv.
Q: Ntev npaum li cas tus qauv rail ntev?
A: Cov pa hluav taws xob sib koom ua ke yog muab rau hauv 12.5 m lossis 25 m ntev. Nruam welded rail yog xa hauv cov hlua ntev ntawm 100-500 m rau kev sib tsoo. Kev cai ntev yog txiav ntawm lub zeb nrog kev kam rau siab txog li +50 hli.
