Dab tsi txiav txim siab lub neej kev pab cuam ntawm S20 kev lag luam khiav?
Lub neej ua haujlwm ntawm aDIN 5901 S20 railyog txiav txim los ntawm ib tug ua ke ntawm metallurgical zoo, ua hauj lwm ib puag ncig, thiab installation precision. Thaum lub S20 yog lub teeb rail profile (19.80 kg / m), nws lub neej ntev nyob rau hauv kev lag luam chaw xws li gantry crane runways lossis mining loops nyob ntawm seb nws tiv taus hnav, qaug zog, thiab ib puag ncig corrosion.
- Khoom Qib Xaiv:Qhov no yog ib qho tseem ceeb tshaj plaws. Xaiv55Q (siab- carbon steel) tshajQ235B (cov qauv hlau) tuaj yeem ua peb npaug ntawm txoj kev taug txoj sia nyob rau hauv siab -kev sib txhuam ib puag ncig.
55 Q qib:Muaj qhov hardness ntawm 200-240 HB. Cov pa roj carbon siab no-manganese tshuav nyiaj li cas tso cai rau txoj kev tsheb ciav hlau los tiv thaiv kev hnav ntawm steel log.
Q235B Qib:Tsuas yog 140-160 HB. Hauv siab - siv ntau zaus, lub taub hau Q235B rail yuav flatten los yog "nceb" sai, yuav tsum tau hloov thaum ntxov.

Siv cov khoom siv hluav taws xob S20 qhov tseeb kom ntseeg tau tias 30 hli lub taub hau tswj hwm nws qhov profile, uas yog qhov tseem ceeb rau kev mus ncig ntawm cranes thiab tiv thaiv kev puas tsuaj rau lub tshuab lub log bearings.
- Log-rau-Rail Interaction:Kev sib cuag ntawm lub log tsheb thiab 30 hli S20 rail lub taub hau dav dictates tus nqi ntawm deformation deformation los yog "mushrooming."
- Maintenance ntawm Joints:Qhov xwm txheej ntawm S20 rail fishplates thiab bolts. Cov pob qij txha xoob ua rau "kev puas tsuaj," qhov twg cov tsheb ciav hlau xaus yog hammered los ntawm lub log dhau.
- Environmental Corrosion:Kev cuam tshuam rau cov dej noo, tshuaj, lossis ntsev hauv cov chaw tsim khoom tuaj yeem ua rau pitting thiab seem poob, nws thiaj li txo qhov S20 rail load peev.
GNEE RAILtsom rau kev ua kom lub neej ntev ntev los ntawm kev muab siab -purity 55Q cov ntaub ntawv thiab precision- dov profiles. Los ntawm kev ua raws li tus qauv DIN 5901 nruj me ntsis, peb xyuas kom meej tias S20 rail specifications tseem zoo ib yam nyob rau hauv tag nrho cov project, txo cov neeg kho tshuab vibrations uas ua rau qaug zog ntxov ntxov.
Dab tsi yog qhov ntev ntawm S20 lub teeb rail?
CovS20 lub teeb railyog qhov nruab nrab - hnyav hlau profile txhais los ntawm DIN 5901 tus qauv. Nws yog dav siv nyob rau hauv industrial chaw xws li Hoobkas hauv pem teb systems, warehouse logistics, thiab mining lem.
Raws li DIN 5901, qhov tseeb tus qauv qhov ntev yog:
- Rail Qhov siab:100 hli (kwv yees . 3.94 ntiv tes)
- Lub hauv paus dav:82 hli (kwv yees . 3.23 nti)
- Lub taub hau dav:44 hli (kwv yees . 1.73 ntiv tes)
- Web Thickness:10 hli (kwv yees . 0.39 ntiv tes)
- Qhov hnyav:19.8 kg/m (kwv yees . 39.9 lbs/yd)

FAQ
- S20 rail feem ntau kav ntev npaum li cas?
Hauv cov qauv teeb pom kev zoo- lub tsev khaws khoom ua haujlwm (siv qib 55Q), S20 rail yuav kav ntev li 15-20 xyoo. Hauv qhov siab - tsheb khiav kuv, lub neej yuav yog 5-8 xyoo vim muaj plua plav ore abrasive.
- Puas yog tshuaj tiv thaiv- xeb txheej txuas ntxiv lub neej?
Yog lawm. Rau cov chaw ntug dej hiav txwv lossis cov chaw siv tshuaj, galvanizing lossis los tiv thaiv- pleev xim rau kev xeb tiv thaiv S20 rail hla ntu ntawm thinning vim xeb.
- Kuv puas tuaj yeem rov rub lub taub hau tsheb ciav hlau kom ntev nws lub neej?
Yog tias S20 rail lub taub hau dav muaj me me "nceb", lub teeb sib tsoo tuaj yeem rov qab tau qhov profile. Txawm li cas los xij, yog tias lub taub hau qhov siab tau txo qis, S20 rail load peev yuav raug cuam tshuam.
- Dab tsi yog txoj hauv kev zoo tshaj plaws los tiv thaiv kev tsheb ciav hlau buckling?
Xyuas kom meej tias S20 rail sib koom ua ke tau nruab nrog qhov sib txawv ntawm qhov tseeb (feem ntau 2-4 hli) thiab cov rail clips tso cai rau me ntsis kev txav mus los ntev.
- Puas yog ib lub tsheb hnyav hnyav ib txwm nyob ntev dua?
Feem ntau, yog. Txawm li cas los xij, ib qho S20 ua los ntawm 55Q feem ntau yuav dhau los ntawm kev hnyav hnyav ua los ntawm cov hlau mos vim tias nws tiv taus qhov hnav zoo dua.
- Kuv yuav ua li cas thiaj paub thaum lub sijhawm hloov tsheb ciav hlau?
Hloov cov tsheb ciav hlau yog tias lub taub hau hnav ntau dua 25% ntawm qhov siab ntawm 30 hli qub, yog tias pom cov kab nrib pleb hauv lub vev xaib, lossis yog tias S20 rail specifications rau kev ncaj yuav tsis tuaj yeem ua tau.
