NtawmGNEE RAIL, kev xaiv cov khoom yog nruj me ntsis tswj thaum lub sij hawm tsim khoom. Txhuaua 60 railyog tsim los siv cov qib steel tsim nyog thiab cov txheej txheem dov zoo ib yam kom ruaj khov60 lbs rail qhov ntev hauv mm, txhim khu kev qha txhua yam kev ua tau zoo, thiab kev ua haujlwm ntev - nyob rau hauv kev rov ua dua.
Dab tsi yog cov khoom siv hauv ASCE 60 Rail Manufacturing?
ASCE 60 rail manufacturing feem ntau siv siab - purity carbon steel, xws li Q235B, 55Q, thiab U71Mn. Cov ntaub ntawv no yog tsim los ntawm cov pa hluav taws xob yooj yim (BOF) lossis hluav taws xob arc furnaces (EAF), ua raws li kub dov. Cov ntaub ntawv no muaj lub zog siab, hnav tsis kam, thiab ua haujlwm ntev, haum rau lub teeb -load, mining, thiab gantry crane systems.
- U71Mn (Manganese hlau):Feem ntau siv rau cov ntawv thov kom muaj zog dua, hnav tsis kam, thiab txhim kho durability tiv thaiv kev ua haujlwm tsis tu ncua.

- Manufacturing Standards:Feem ntau tsim raws li ASTM A1 / AREMA cov qauv, kom ntseeg tau tias kev ua haujlwm zoo ib yam.
- Khoom:Cov hlau no muab lub zog siab, hnav tsis kam, thiab qaug zog ua haujlwm siab.
Cov ntaub ntawv cuam tshuam li cas rau Rail Performance?
Cov khoom siv nyob rau hauv asce 60 rail ncaj qha cuam tshuam qhov kev tsheb ciav hlau ua haujlwm thaum lub sijhawm ua haujlwm. Nws tsis yog tsuas yog hais txog lub zog, tab sis kuj hais txog yuav ua li cas lub tsheb ciav hlau coj tus cwj pwm nyob rau hauv kev ntxhov siab thiab ib puag ncig ib puag ncig.
Ib qib zoo xaiv steel txhim kho kev hnav tsis kam ntawm lub taub hau tsheb ciav hlau, txo cov khoom poob los ntawm kev sib cuag log. Nws kuj tseem txhim kho lub zog qaug zog, tso cai rau txoj kev tsheb ciav hlau tuaj yeem tiv thaiv kev thauj mus los tsis tau tawg.
Impact toughness yog lwm yam tseem ceeb. Nyob rau hauv ib puag ncig kev lag luam uas yuav tshwm sim tam sim ntawd, lub tsheb ciav hlau yuav tsum tiv thaiv kev puas tsuaj thiab tswj kev ruaj ntseg.
NtawmGNEE RAIL, cov khoom siv tswj ua ke nrog qhov tseeb asce 60 rail qhov ntev kom ntseeg tau tias txhua 60 lb ASCE rail muab kev ua haujlwm zoo ib yam thiab ua haujlwm ntev dua.
