Xov Xwm - Koj puas paub txog AREMA Standard Steel Rail?

Cov txheej txheem tsim khoom ntawmAREMA tus qauv hlau railfeem ntau suav nrog cov kauj ruam hauv qab no:
Kev npaj cov khoom siv raw: Npaj cov khoom siv raw rau hlau, feem ntau yog cov hlau carbon zoo lossis cov hlau tsis tshua muaj hlau.
Kev Smelting thiab casting: Cov khoom siv raw yog smelted, thiab tom qab ntawd cov hlau molten yog pov rau hauv cov hlau billets ua ntej los ntawm kev casting tas mus li lossis nchuav.
Kev ua kom zoo thiab dov: Kev ua kom zoo cov hlau billet ua ntej, suav nrog kev tshem tawm cov khoom tsis huv thiab kho cov khoom sib xyaw, thiab tom qab ntawd dov cov hlau billet los ntawm cov khoom siv dov mus rau hauv cov hlau billets uas ua tau raws li cov qauv hauv tebchaws.
Kev kho ua ntej: Kev kho ua ntej ntawm cov hlau billets, suav nrog kev forging, kev kho cua sov thiab kev kho qhov chaw, thiab lwm yam, los txhim kho lub zog thiab kev ruaj khov ntawm cov hlau.
Dov thiab tsim: Cov hlau billet uas tau kho ua ntej lawm yog dov thiab tsim los ntawm lub tshuab dov kom ua rau nws mus rau hauv cov qauv tsheb ciav hlau uas ua tau raws li cov qauv hauv tebchaws.
Kev tshuaj xyuas thiab kev tswj xyuas zoo: Kev tshuaj xyuas nruj thiab kev tswj xyuas zoo raug ua tiav ntawm cov kev tsheb ciav hlau tsim tawm kom ntseeg tau tias lawv ua tau raws li cov qauv hauv tebchaws thiab cov kev xav tau ntawm cov neeg siv khoom.
Ntim thiab tawm hauv lub Hoobkas: Cov hlau uas tsim nyog tau ntim thiab cim, thiab tom qab ntawd xa mus rau tus neeg siv khoom lossis khaws cia rau hauv lub tsev rau khoom tos kev xa khoom.

ASTM tus qauv hlau rail muaj cov yam ntxwv hauv qab no:

Lub zog siab: Tus qauv Asmeskascov ntsia hlauyog ua los ntawm cov hlau zoo, uas muaj lub zog siab thiab ruaj khov thiab tuaj yeem tiv taus qhov siab hnyav thiab kev cuam tshuam ntawm kev ua haujlwm ntawm tsheb ciav hlau.

Kev teeb tsa cov lus qhia tshwj xeeb: Cov lus qhia thiab qhov ntev ntawm American standard rails raug tsim los raws li cov qauv, kom ntseeg tau tias muaj kev sib xws thiab kev sib pauv ntawm txoj kev tsheb ciav hlau.

Kev tiv thaiv kev hnav zoo: Qhov saum npoo ntawm American standard rails tau raug kho tshwj xeeb thiab muaj kev tiv thaiv kev hnav zoo, uas tuaj yeem txo qhov kev hnav ntawm txoj kev thiab txuas ntxiv lub neej kev pabcuam.

Kev tiv thaiv xeb zoo: Qhov saum npoo ntawm American standard rails tau dhau los ua kev kho mob tiv thaiv xeb, uas tuaj yeem tiv taus oxidation thiab corrosion thiab tswj tau qhov zoo ntawm kev siv.

Kev siv dav dav: Cov tsheb ciav hlau txheem Asmeskas yog qhov tsim nyog rau ntau txoj kab tsheb ciav hlau, suav nrog cov tsheb ciav hlau ceev ceev, cov tsheb ciav hlau ib txwm muaj thiab cov tsheb ciav hlau thauj khoom, thiab lwm yam, thiab muaj kev hloov pauv ntau yam thiab kev siv tau.

Txoj kev tsheb ciav hlau Asmeskas:
