A rail ntses phajyog ib qho steel sib koom ua ke ntawm ob sab ntawm lub vev xaib kev tsheb nqaj hlau kom txuas ob txoj kev tsheb ciav hlau xaus rau hauv kev thauj khoom tas mus li -cov tswvcuab bearing, tso cai rau lub log loads hla kev sib koom ua ke yam tsis muaj kev hloov pauv sai. Nws lub luag haujlwm tseem ceeb yog txhawm rau txhim kho cov txheej txheem txuas ntxiv uas cov tsheb ciav hlau tsis welded.
GNEE RAILkhoom siv ntses daim hlau sib tw rau GB 8-60 kg / m rails, UIC50/54/60, DIN536 A55-A120 crane rails, QU70-QU120, JIS rail series, AS1085 seem, BS11 profiles, thiab AREMA / ASCE rail qauv, nrog rau tag nrho cov kev sib koom tes, cov khoom siv ntxhua khaub ncaws.
Dab tsi yog txoj haujlwm ntawm kev sib koom ua ke ntawm kev tsheb nqaj hlau?
Rail pob qij txha (los yog ntses phaj) yog ib qho tseem ceeb ntawm txoj kev tsheb ciav hlau uas txuas cov tsheb ciav hlau uas nyob ib sab, ua kom muaj kev txuas ntxiv, kev sib raug zoo, thiab cov qauv kev ruaj ntseg rau kev nyab xeeb kev tsheb ciav hlau. Lawv tso cai rau thermal expansion/contraction, txo lub log cuam tshuam, thiab pab kom yooj yim rail hloov.
Lub luag haujlwm tseem ceeb ntawm kev sib koom ua ke rail muaj xws li:
- Structure Integrity:Lawv txuas cov kev tsheb ciav hlau xaus, tswj kev khiav mus tas li thiab txhawb nqa cov tsheb ciav hlau hla.
- Alignment Control:Lawv khaws cov kev tsheb ciav hlau xaus ua ke horizontally thiab vertically kom tsis txhob derailment.
- Thermal Management:Lawv tso cai rau kev cog lus thiab nthuav dav ntawm cov ntsia hlau vim qhov kub hloov pauv.
- Qhov cuam tshuam:High- cov pob qij txha zoo txo qhov cuam tshuam rau ntawm txoj kev tsheb ciav hlau xaus ntawm lub tsheb ciav hlau log.
- Versatility:Cov hom tshwj xeeb, xws li cov pob qij txha insulated, yog siv rau kev taw qhia, thaum lwm tus, xws li cov pob qij txha sib txuas, txuas cov hlua sib txawv ntawm qhov hnyav lossis ntu.
Yuav ua li cas railfish daim hlau tsim? Cov ntaub ntawv dab tsi yog lawv ua los ntawm?
Rail ntses daim hlau (los yog sib koom ua ke) yog tsim los ntawm kub dov, forging, thiab precision machining ntawm siab -lub zog carbon los yog hlau alloy steel (xws li Q235, 45 #, 50 #, los yog 55Q) kom ruaj khov, siab tensile zog, thiab cuam tshuam tsis kam. Cov txheej txheem suav nrog shaping, xuas nrig ntaus lub qhov, thiab kev kho cua sov los txhim kho kev hnav tsis kam.
Kev tsim khoom
- Kev xaiv khoom siv:High - steel zoo yog xaiv rau nws cov neeg kho tshuab lub zog, feem ntau raug kuaj rau tensile lub zog thiab hardness.
- Shaping (Kub Rolling / Forging):Hlau yog rhuab thiab dov los yog forged rau hauv cov ntses phaj profile. Forging yog siv rau siab dua - qhov yuav tsum tau muaj zog.
- Machining:Bolt qhov yog drilled los yog xuas nrig ntaus kom meej qhov ntev, thiab cov npoo tiav los xyuas kom haum.
- Kev kho cua sov:Cov paib tau quenching thiab tempering (hardening) kom hnav tsis kam thiab kev pab lub neej.
- Quality Control & Finishing:Kev tshuaj xyuas zaum kawg tshawb xyuas qhov tseeb qhov tseeb thiab qhov tsis xws luag, ua raws li kev tiv thaiv -corrosive txheej.
Cov ntaub ntawv siv
- Carbon Steel:Q235, Q345, 45 #, 50 #, 55Q, 71Mn, lossis 75V yog ib txwm, xaiv raws li qhov xav tau lub zog thiab hom kev tsheb nqaj hlau.
- Hlau alloy:Siv rau kev siv kev ntxhov siab ntau dua.
- Nodular Cam khwb cia hlau:Qee zaum siv rau cov hom tshwj xeeb.
- Khoom siv tshwj xeeb:Rau cov pob qij txha insulated, siab - lub zog sib xyaw lossis hlau nrog cov txheej rwb thaiv tsev yog siv.
