Txij li thaum xyoo 2012, kev txhim kho thiab ntawv pov thawj ntawm railway steel khoom, cov khoom tsim muaj ntau yam kev siv, npog bogie steel phaj, lub zog locomotive txhawb steel phaj, steel phaj rau tsheb lub cev, monorail turnout steel phaj thiab lwm yam. Cov neeg muas zaub tseem ceeb yog Puzhen dov Tshuag Hoobkas, Qingdao Sifang, Datong dov Tshuag Hoobkas, Zhuzhou dov Tshuag Hoobkas, Jinan dov Tshuag Hoobkas, Changzhou Qishuyan locomotive dov Tshuag Hoobkas, Ziyang dov Tshuag Hoobkas, Wuhan Changjiang dov Tshuag Hoobkas, Xi'an dov Tshuag Hoobkas.

Nyob rau hauv xyoo tsis ntev los no, nrog rau kev loj hlob ntawm lub teb chaws railway kev lag luam, lub tuam txhab cov steel phaj muag tau pom ib tug loj hlob sai. Nyob rau hauv 2019, nws tau ua tiav dhau ISO / TS22163: 2017 tus qauv ntawv pov thawj, thiab yog tib lub tuam txhab steel hauv kev lag luam uas tau dhau qhov nyiaj tau txais txiaj ntsig ntawm ISO / TS22163: 2017 tus qauv txheej txheem. Cov khoom zoo thiab kev xa khoom tau lees paub thiab qhuas los ntawm cov neeg siv khoom.

Rail steel, tseem hu ua rail track steel, yog hom tshwj xeeb ntawm cov hlau tsim los siv hauv kev tsheb ciav hlau. Hom hlau no yuav tsum ua kom tau raws li qhov yuav tsum tau ua kom nruj kom tiv taus qhov hnyav hnyav, kev ntxhov siab rov ua dua, thiab hnav cuam tshuam nrog kev txav ntawm cov tsheb ciav hlau. Cov khoom ntawm rail steel yog ua tib zoo tsim kom muaj kev nyab xeeb, kev ua neej ntev, thiab kev ua haujlwm zoo hauv kev tsheb ciav hlau.

Composition thiab Manufacturing: Rail steel feem ntau yog cov pa roj carbon tsawg, siab-manganese hlau nrog cov khoom siv ntxiv xws li silicon thiab qee zaus chromium. Qhov tshwj xeeb muaj pes tsawg leeg yog ua tib zoo xaiv kom ua tiav qhov sib npaug ntawm hardness, toughness, thiab tsis kam hnav. Cov txheej txheem tsim khoom suav nrog kub dov, uas muab cov khoom xav tau rau cov hlau.

Cov yam ntxwv ntawm Rail Steel:

High Hardness: Rail steel yuav tsum muaj zog txaus los tiv thaiv hnav thiab deformation los ntawm kev sib txhuam tsis tu ncua ntawm lub tsheb ciav hlau log thiab cov tsheb ciav hlau. Qhov hardness no ua kom lub neej ntev kev pab cuam rau cov ntsia hlau.

Toughness: Txawm tias nws hardness, rail steel yuav tsum muaj toughness los tiv thaiv tej yam loads thiab tiv taus nkig tawg. Toughness yog qhov tseem ceeb rau kev tiv thaiv kev tsheb ciav hlau tsis ua haujlwm thiab ua kom muaj kev nyab xeeb ntawm kev thauj mus los.

Hnav Resistance: Qhov kev txav mus tas li ntawm cov tsheb ciav hlau hla cov ntsia hlau ua rau cov hlau tseem ceeb heev. Rail steel yog tsim los ua kom pom kev hnav zoo heev, txo qhov xav tau kev hloov pauv thiab tu.

Ductility: Rail steel yuav tsum muaj cov hlua txaus kom nqus tau thiab rov faib cov kev ntxhov siab, tshwj xeeb tshaj yog nyob rau hauv cov pob qij txha thiab kev hloov pauv. Ductility pab tiv thaiv kev txhim kho ntawm cov kab nrib pleb thiab ua kom muaj kev ncaj ncees tag nrho ntawm cov qauv tsheb ciav hlau.

Resistance rau Rolling Contact Fatigue: Rail steel yog raug rau dov kev sib cuag qaug zog vim qhov rov ua dua thiab tshem tawm los ntawm kev hla tsheb ciav hlau. Nws muaj pes tsawg leeg thiab kev kho cua sov yog optimized los tiv thaiv txoj kev loj hlob ntawm qaug zog tawg.

Daim ntawv thov: Rail steel feem ntau yog siv rau hauv kev tsim kho ntawm txoj kev tsheb ciav hlau, suav nrog ntau yam kev tsheb ciav hlau xws li:

Rails: Lub ntsiab kab rov tav Cheebtsam uas txhawb nqa thiab coj lub tsheb ciav hlau log. Cov no yog cov tseem ceeb load-bearing ntsiab ntawm khiav.

Hloov thiab Hla: Cov khoom tseem ceeb uas cov tsheb ciav hlau tuaj yeem hloov tau. Cov hlau siv hauv cov keyboards thiab hla yuav tsum muaj cov khoom zoo sib xws rau cov hlau rail.

Fasteners: Ntau lub tshuab fastening, xws li clips thiab bolts, yog siv los tuav cov ntsia hlau rau cov hlua khi lossis cov neeg pw tsaug zog. Cov fasteners feem ntau yog ua los ntawm cov hlau sib xws nrog rail steel.

Standards thiab Specifications: Rail steel yuav tsum ua raws li cov qauv tshwj xeeb thiab cov qauv tsim los ntawm cov tub ceev xwm thiab cov koom haum. Cov qauv no txhais cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab cov kev xav tau zoo rau cov hlau rail kom ntseeg tau tias muaj kev sib haum xeeb thiab kev nyab xeeb thoob plaws hauv kev tsheb ciav hlau.

Xaus: Rail steel yog cov khoom tshwj xeeb uas ua lub luag haujlwm tseem ceeb hauv kev nyab xeeb thiab ua haujlwm zoo ntawm kev tsheb ciav hlau. Nws qhov tshwj xeeb ua ke ntawm hardness, toughness, thiab hnav tsis kam ua kom cov kav ntev thiab kev ntseeg siab ntawm kev tsim kho tsheb ciav hlau, ua rau muaj kev nyab xeeb tag nrho thiab kev ua haujlwm ntawm kev thauj mus los thoob ntiaj teb. Raws li kev siv thev naus laus zis, kev tshawb fawb tsis tu ncua thiab kev txhim kho txuas ntxiv txhim kho kev ua tau zoo thiab kev ua haujlwm ntev ntawm kev tsheb nqaj hlau hlau hauv kev hloov pauv ntawm kev thauj mus los.
