Heavy Industrial Rail Track Siv Rail Hlau Lub Ntsiab Ntawm Txoj Kev Tsheb Ciav Hlau thiab Khiav Circuit Court Q275 20Mnk Rail Steel
kev tsheb ciav hlau railfeem ntau yog tsim nyob rau hauv tus qauv ntev ntawm 30 ko taw, 39 ko taw, los yog 60 ko taw, txawm hais tias ntev rails tseem tuaj yeem tsim rau cov haujlwm tshwj xeeb. Feem ntau hom steel rail siv nyob rau hauv railway lem yog hu ua flat-bottomed rail, uas muaj ib tug ca puag thiab ob lub kaum sab xis. Qhov hnyav ntawm txoj kev tsheb ciav hlau, hu ua nws "poundage," nws txawv nyob ntawm seb cov kev cai tshwj xeeb ntawm txoj kab tsheb ciav hlau.
Cov txheej txheem ntau lawm ntawmkev tsheb ciav hlau railsuav nrog ntau cov kauj ruam, suav nrog:
- Raw khoom npaj: Kev tsim khoom ntawmrailway hlaupib nrog kev xaiv thiab npaj cov khoom siv raw, feem ntau yog cov khoom zoo steel billets. Cov pob zeb no yog tsim los ntawm cov hlau ore thiab lwm yam khoom siv ntxiv, xws li limestone thiab coke, uas tau yaj hauv qhov cub tawg kom tsim cov hlau molten.
- Nruam casting: Cov hlau molten yog ces pauv mus rau lub tshuab nruam nruam, qhov twg nws yog poured rau hauv pwm los ua ntev nruam strands hu ua billets. Cov billets no feem ntau yog cov duab plaub thiab muab cov khoom pib rau txoj kev tsheb ciav hlau.
- Cua sov thiab dov: Cov billets yog reheated nyob rau hauv ib lub qhov cub rau qhov kub thiab txias uas tso cai rau lawv kom yooj yim zoo li tus thiabsteel railroad khiav. Tom qab ntawd lawv tau dhau los ntawm ntau cov dov mills, uas ua rau lub zog loj heev los tsim cov pob zeb rau hauv qhov xav tau rail profile. Cov txheej txheem dov muaj ntau qhov kev rov ua dua ntawm kev hla cov billets los ntawm cov dov mills kom maj mam ua rau lawv mus rau hauv kev sib tw.
- Txias thiab txiav: Tom qab cov txheej txheem dov, cov ntsia hlau tau txias thiab txiav mus rau qhov ntev. Lawv feem ntau txiav rau hauv cov qauv ntev ntawm 30 ko taw, 39 ko taw, lossis 60 ko taw, txawm hais tias ntev ntev kuj tuaj yeem tsim rau cov haujlwm tshwj xeeb.
- Kev tshuaj xyuas thiab kev kho mob: Cov tsheb ciav hlau ua tiav tau soj ntsuam nruj kom ntseeg tau tias lawv ua tau raws li cov qauv kev lag luam thiab cov lus qhia tshwj xeeb. Ntau yam kev ntsuam xyuas, xws li kev ntsuas qhov ntev, tshuaj ntsuam xyuas, thiab kev ntsuas tshuab, yog ua los xyuas qhov zoo thiab kev ncaj ncees ntawm cov ntsia hlau. Txhua qhov tsis xws luag lossis tsis zoo yog raug txheeb xyuas thiab koom nrog.
- Kev kho deg: Txhawm rau txhim kho cov kav ntev thiab kev tiv thaiv corrosion ntawm cov ntsia hlau, lawv tuaj yeem raug kho cov txheej txheem saum npoo. Qhov no tuaj yeem suav nrog kev siv cov tshuaj tiv thaiv, xws li cov tshuaj tiv thaiv corrosion lossis galvanization, txhawm rau tiv thaiv xeb thiab xeb, yog li txuas lub neej ntev ntawm cov ntsia hlau.
- Kev tshuaj xyuas zaum kawg thiab ntim khoom: Thaum cov ntsia hlau tau kho thiab dhau qhov kev tshuaj xyuas zaum kawg, lawv tau ua tib zoo ntim rau kev thauj mus los rau cov chaw tsim kho tsheb ciav hlau. Lub ntim yog tsim los tiv thaiv cov ntsia hlau los ntawm kev puas tsuaj thaum caij tsheb npav.
Nta
steel railsyog ib qho tseem ceeb ntawm txoj kev tsheb ciav hlau thiab muaj ob peb yam tseem ceeb:
1. Lub zog thiab Durability: Cov hlau ntsia hlau yog tsim los ntawm cov hlau zoo, uas ua rau lawv muaj zog thiab ua haujlwm ntev. Lawv tau tsim los tiv taus cov khoom hnyav, kev cuam tshuam tsis tu ncua, thiab huab cua huab cua tsis muaj qhov cuam tshuam loj lossis puas tsuaj.
2. Muaj peev xwm Load-Bearing Capacity: Steel rails yog engineered los txhawb nqa qhov hnyav ntawm cov tsheb ciav hlau thiab lawv cov khoom thauj. Lawv tuaj yeem tuav cov khoom hnyav thiab faib qhov hnyav sib npaug, txo qhov kev pheej hmoo ntawm kev khiav tsis ua haujlwm lossis deformation.
3. Wear Resistance: steel rails muaj kev tiv thaiv siab rau hnav thiab puas. Qhov no yog qhov tseem ceeb vim tias cov tsheb ciav hlau tsis tu ncua khiav ntawm txoj hlua, ua rau muaj kev sib txhuam thiab hnav lub sijhawm. Cov hlau siv hauv kev tsim tsheb ciav hlau tshwj xeeb yog xaiv rau nws lub peev xwm los tiv thaiv hnav thiab tswj nws cov duab nyob rau lub sijhawm ntev ntawm kev siv txuas ntxiv.
4. Dimensional Accuracy: steel rails yog tsim los kom nruj me ntsis kam rau ua kom muaj kev sib raug zoo thiab kev ua haujlwm zoo nrog rau lwm yam kev tsheb ciav hlau, xws li cov pob qij txha, kev sib tw, thiab cov fasteners. Qhov no tso cai rau seamless txav ntawm cov tsheb ciav hlau raws txoj kev thiab txo cov kev pheej hmoo ntawm derailments los yog cuam tshuam.
5. Corrosion Resistance: steel rails feem ntau raug kho nrog cov txheej tiv thaiv los yog undergo galvanization los txhim kho lawv cov kev tiv thaiv corrosion. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas muaj cov av noo siab, corrosive ib puag ncig, los yog raug dej, vim corrosion tuaj yeem ua rau cov ntsia hlau tsis muaj zog thiab cuam tshuam lawv cov qauv kev ncaj ncees.
6. Lub neej ntev: steel rails muaj lub neej ntev kev pab cuam, uas ua rau tag nrho cov nqi-zoo ntawm railway infrastructure. Nrog kev saib xyuas kom zoo thiab kev tshuaj xyuas ib ntus, cov hlua hlau tuaj yeem nyob ntev li ntau xyoo ua ntej yuav tsum tau hloov.
7. Standardization: Steel rails yog tsim raws li cov qauv kev lag luam thiab cov kev qhia tshwj xeeb uas tsim los ntawm cov koom haum xws li American Society for Testing and Materials (ASTM) lossis International Union of Railways (UIC). Qhov no ua kom ntseeg tau tias steel rails los ntawm cov tuam txhab sib txawv tuaj yeem hloov pauv tau yooj yim thiab sib xyaw ua ke rau hauv cov tsheb ciav hlau uas twb muaj lawm.
Daim ntawv thov
Steel rails feem ntau yog siv rau kev tsim kho ntawm txoj kev tsheb ciav hlau, tso cai rau cov tsheb ciav hlau thauj cov neeg caij tsheb thiab cov khoom siv tau zoo. Txawm li cas los xij, lawv muaj ob peb lwm daim ntawv thov thiab:
1. Tram thiab Light Rail Systems: Steel rails yog siv nyob rau hauv tram thiab lub teeb rail systems coj lub log ntawm lub tsheb raws txoj kev. Cov kab ke no feem ntau pom muaj nyob hauv nroog thiab muab kev thauj mus los hauv nroog thiab hauv nroog.
2. Industrial thiab Mining Tracks: steel rails yog siv rau hauv kev lag luam chaw, xws li cov chaw tsim khoom lossis cov chaw mining, los txhawb kev thauj mus los ntawm cov khoom hnyav thiab cov khoom siv. Lawv feem ntau muab tso rau hauv warehouses lossis yards, txuas cov chaw ua haujlwm sib txawv lossis chaw cia khoom.
3. Chaw nres nkoj thiab Terminal Tracks: steel rails yog siv nyob rau hauv cov chaw nres nkoj thiab terminals los pab txhawb kev txav ntawm cov khoom thauj. Lawv tau muab tso rau hauv cov chaw nres nkoj lossis hauv thaj chaw cia kom muaj kev thauj khoom thiab tshem tawm cov nkoj thiab ntim khoom.
4. Cov Chaw Ua Si thiab Cov Menyuam Yaus Coasters: Cov hlua hlau yog ib feem tseem ceeb ntawm cov menyuam coasters thiab lwm yam kev lom zem ua si. Lawv muab cov qauv thiab lub hauv paus rau kev khiav, ua kom muaj kev nyab xeeb thiab kev ua haujlwm zoo ntawm kev caij tsheb.
5. Conveyor Systems: steel rails tuaj yeem siv rau hauv cov tshuab conveyor, uas yog siv ntau yam kev lag luam los thauj cov khoom lossis cov ntaub ntawv raws li txoj kev ruaj khov. Lawv muab txoj kev ruaj khov thiab txhim khu kev qha rau cov siv conveyor kom khiav mus.
6. Cov Kev Ua Si Ib ntus: Cov hlua hlau tuaj yeem siv tau los ua cov lem ib ntus hauv cov chaw tsim kho lossis thaum lub sijhawm tu cov haujlwm. Lawv tso cai rau kev txav ntawm cov tshuab hnyav thiab cov khoom siv, ua kom muaj kev ua haujlwm zoo yam tsis muaj kev puas tsuaj rau hauv av.
