Lub tsheb ciav hlau steel yog ib qho tshwj xeeb, hnyav- lub luag haujlwm steel bar, feem ntau muaj qhov hloov pauv 'T' zoo li, tsim cov kev taw qhia tseem ceeb thiab thauj khoom -cov kabmob nto rau tsheb ciav hlau, tsheb ciav hlau, thiab cranes, tsim los tiv taus qhov siab loj, kev sib txhuam, thiab kev cuam tshuam thaum muab txoj kev du, txuas mus ntxiv rau lub log. Ua los ntawm siab - carbon steel alloys nrog cov ntsiab lus tshwj xeeb xws li manganese, chromium, thiab tooj liab rau kev txhim kho lub zog, ruaj khov, thiab hnav tsis kam, cov ntsia hlau no hloov tsheb thauj mus rau cov neeg pw tsaug zog, ua kom muaj kev nyab xeeb thiab muaj txiaj ntsig zoo.
Lub 60ft rail hnyav npaum li cas?
Ib qho 60-foot rail qhov hnyav sib txawv raws li tus qauv, tab sis ntau hom nyiamUIC60/60E1hnyav ib ncig ntawm 60 kg / meter, tag nrho kwv yees li 3,600 kg (7,937 lbs) rau 60 ko taw (kwv yees 18.288 meters). Asmeskas cov qauv (ASCE) muaj qhov hnyav sib txawv, zoo li ASCE 60, uas yog kwv yees li 29.76 kg / meter, ua 60-ko taw ntu ib ncig ntawm 1,786 kg (3,937 lbs).
Raws li tus kws tshaj lij kev tsheb ciav hlau xa khoom, GNEE RAILcan muab cov txheej txheem sib txawv steel hlau xws li Asmeskas, BS, UIC, DIN, JIS, Australian thiab South Africa uas siv cov kab tsheb ciav hlau, cranes thiab thee mining.

Qhov tseem ceeb ntawm Steel Rail
Qhov tseem ceeb ntawm txoj kev tsheb ciav hlau yog lub taub hau, lub vev xaib, ko taw, lub kaum ntse ntse nuv ntses, thiab qhov siab ntawm txoj kev tsheb ciav hlau. Cov kev xav tau, nrog rau cov kev xav tseem ceeb, rau kev tsim ntawm cov tsheb ciav hlau yog raws li hauv qab no.
- Lub taub hau- Lub taub hau ntawm txoj kev tsheb ciav hlau yuav tsum muaj qhov tob txaus kom tso cai rau kev hnav ntsug. Lub taub hau tsheb ciav hlau yuav tsum yog qhov dav txaus kom tsis yog tsuas yog muaj qhov dav dav dav, tab sis kuj tseem muaj cov tsheb ciav hlau uas xav tau rau sab nraub qaum.
- Web- Lub vev xaib yuav tsum ua kom tuab txaus kom tiv taus cov kev ntxhov siab tshwm sim vim yog cov khoom thauj los ntawm nws, tom qab tso cai rau kev ua haujlwm zoo.
- Ko taw- Cov ko taw yuav tsum muaj cov tuab txaus txhawm rau tiv thaiv txoj kab ntsug thiab kab rov tav tom qab tso cai rau poob vim corrosion. Lub ko taw yuav tsum dav txaus rau stability tiv thaiv overturning. Tus tsim ntawm ko taw yuav tsum yog xws li tias nws tuaj yeem ua lag luam thiab ua tau zoo dov.
- Nuv ntses cov ces kaum- Lub kaum ntse ntse nuv ntses yuav tsum xyuas kom muaj kev sib kis ntawm cov khoom thauj los ntawm cov ntsia hlau mus rau cov phaj ntses. Lub kaum ntse ntse nuv ntses yuav tsum yog qhov nruj ntawm lub phaj tsis tsim kev ntxhov siab ntau dhau ntawm lub vev xaib ntawm txoj kev tsheb ciav hlau.
- Qhov siab ntawm txoj kev tsheb ciav hlau- Qhov siab ntawm txoj kev tsheb ciav hlau yuav tsum tsim nyog kom lub tsheb ciav hlau muaj qhov ntsug txaus thiab lub zog zoo li lub nqaj.
Txij xyoo 2008,GNEE RAILtau muab steel rails ntawm cov qib sib txawv rau ntau tshaj 18 xyoo, steel rails los ntawm GNEE yog heev recommened nyob rau hauv Tuam Tshoj thiab txawv teb chaws.Wtih txiav ntug khoom, GNEE ua tau zoo steel rails uas tau raws li cov kev cai ntawm feem ntau lub teb chaws. Standard rail, lub taub hau hardened rail, hnyav rail, lub teeb rail, crane rail thiab lwm yam yog tag nrho cov muaj nyob ntawm no, raws li ib tug ntawm cov Tuam Tshoj lub ntsiab rail tsum, GNEE RAIL tau ua hauj lwm rau muab kev lag luam ntsuab railway khoom thoob plaws lub ntiaj teb no.
