hlau railyog lub tshav kub-kho pearlitic los yog alloy steel khoom tsim los sib npaug saum npoo hardness nrog rau sab hauv toughness, tso cai rau nws tiv taus hnav, dov kev qaug zog, thiab cuam tshuam kev thauj khoom. Metallurgical huv huv thiab tswj cov txheej txheem txias ua lub luag haujlwm txiav txim siab hauv kev ua haujlwm ntev - lub caij tsheb ciav hlau. Cov yam tseem ceeb no yog qhov tseem ceeb tshwj xeeb hauv kev hnyav - lub luag haujlwm crane lem thiab chaw nres nkoj logistics systems.
GNEE RAIL tsis tsuas yog muab cov khoom siv hauv ntau qib steel xws li 900A, 1100, R260, R350HT, thiab U71Mn, tab sis kuj muab kev xaiv cov khoom siv raws li lub log load, lub voj voog lub luag haujlwm, thiab ib puag ncig raug.
Lub tsheb ciav hlau hu ua dab tsi?
A txoj kev tsheb ciav hlaufeem ntau hu ua a"rail khiav" los yog yooj yim "khiav", thiab nws hais txog cov qauv ua tiav uas coj thiab txhawb nqa tsheb ciav hlau lossis kev tsheb ciav hlau -cov tsheb coj. Hauv cov ntsiab lus engineering, txoj kev tsheb ciav hlau yog ntau tshaj li cov hlau rails; nws yog ib qho system uas muaj ntau yam ua haujlwm ua ke kom muaj kev nyab xeeb, du, thiab ruaj khov tsheb ciav hlau.
Cov khoom tseem ceeb ntawm txoj kev tsheb ciav hlau muaj xws li:
- Rails- Cov hlau tuav uas tsim qhov chaw khiav rau tsheb ciav hlau log. Lawv nqa lub nra thiab coj cov tsheb raws txoj kev ruaj khov.
- Sleepers (Ties)- Kev txhawb nqa kab rov tav (ntoo, pob zeb, lossis hlau) uas tuav cov ntsia hlau ntawm qhov ntsuas kom raug thiab hloov cov khoom thauj mus rau lub hauv paus.
- Fastening Systems- Clips, bolts, lossis cov phiaj hauv paus uas ruaj ntseg rau cov neeg pw tsaug zog thaum tso cai rau qee qhov kev txav mus los.
- Rail Pads- Muab tso rau ntawm txoj hlua thiab cov neeg pw tsaug zog kom txo tau kev co thiab faib kev ntxhov siab.
- Ballast los yog Foundation- Crushed pob zeb lossis lwm yam khoom siv uas txhawb nqa cov neeg pw tsaug zog, muab cov dej ntws tawm, thiab tswj kev sib tw khiav.
Nyob rau hauv kev lag luam chaw, xws li crane rails, "khiav" kuj tseem muaj xws li cov paib hauv paus, embedded foundations, thiab tshwj xeeb rails rails, tab sis lub hauv paus ntsiab lus yog tib yam: rails + kev txhawb nqa + fasteners=khiav system.
Dab tsi yog lub luag haujlwm ntawm kev tsheb ciav hlau hauv kev tsheb ciav hlau?
Lub luag hauj lwm ntawm cov tsheb ciav hlau hauv kev tsheb ciav hlau yog muab qhov nruam, du, qis - kev sib txhuam nto rau cov tsheb ciav hlau khiav, coj lub log tom qab, thiab ua kom cov khoom hnyav los ntawm lub log mus rau cov neeg pw tsaug zog thiab ballast hauv qab no, thaum tiv taus qhov loj loj ntsug thiab sab nraud los ntawm kev txav tsheb ciav hlau. Lawv tsim txoj hauv kev tseem ceeb, ua kom muaj kev txav tau zoo, kev taw qhia, thiab kev thauj khoom thauj khoom kom muaj kev nyab xeeb thiab ruaj khov kev tsheb ciav hlau.
Lub luag haujlwm tseem ceeb ntawm Rails:
Kev taw qhia:Rails ua raws li kev taw qhia nto, ua kom lub tsheb ciav hlau log ntawm txoj kev npaj.
Load Distribution:Lawv hloov qhov hnyav thiab quab yuam los ntawm lub tsheb ciav hlau ( ntsug, braking, thermal) mus rau cov neeg pw tsaug zog, uas tom qab ntawd kis tau cov load rau ballast thiab tsim.
Smooth Movement:Lawv cov tawv tawv, du steel nto tsim kev sib txhuam qis heev nrog cov log hlau, ua kom muaj txiaj ntsig zoo, lub zog -txuag kev mus ncig.
Kev them nyiaj yug tus qauv:Rails muab lub zog thiab durability rau cov qauv khiav, tso cai rau nws dais kev ntxhov siab yam tsis muaj kev tawg lossis deforming ntau dhau.
Foundation:Lawv tsim lub hauv paus khiav saum npoo uas tag nrho cov tsheb ciav hlau ua haujlwm.
