Ki materyèl yo itilize pou ray tren yo?
Jan 21, 2026
tren asye, ki rele tou tren tren, tras asye, se eleman prensipal la nan tren tren. Fonksyon li se gide wou yo nan locomotive a, pote gwo presyon nan wou a, epi kenbe estabilite nan transpò tren. Rail la dwe bay sifas woule kontinyèl, lis ak minimòm pou wou yo. Nan tren elèktrifye oswa seksyon blòk otomatik, tren kapab tou itilize kòm yon sikwi òbital.
Ki materyèl yo itilize pou ray tren yo?
Tren tren yo fabrike soti nanmwayen-a-segondè kabòn alyaj asye, pa soti nan asye estriktirèl komen tankou Q235B, paske ray yo dwe reziste mete sifas ak deformation plastik anba kontak wou konsantre. Asye ray tipik yo genyen nivo kontwole kabòn ak Manganèz, pafwa ak vanadyòm oswa chromium, pou amelyore dite ak rezistans fatig apre woule cho ak refwadisman kontwole.

Pandan keQ235B asyese lajman ki itilize pou plak debaz, travès, ak ray transpò limyè, li pa apwopriye pou gwo -vitès oswa lou- tren tren akòz dite sifas ensifizan. Se poutèt sa operatè tren yo presize klas tankouR260 oswa U71Mn, ki optimize pou kondisyon kontak woule.

Èske menm materyèl yo itilize pou ray teknik ak ray tren?
Malgre ke tou de se ray asye, sistèm teknik anjeneral mande poudiferan karakteristik pèfòmans asyeakòz pi wo chaj wou vètikal ak pi ba vitès vwayaj. Ray teknik yo souvan itilizeU71Mn oswa 50Mn asyekonbine avèk pwofil lajè-baz pou pi bon distribisyon chaj sou travès asye.

Se poutèt sa pwojè tankou tèminal kontenè yo souvan pwokire de sistèm materyèl alafwa: gwo -fatig ray tren pou mouvman tren ak gwo-ray trepye chaj pou operasyon portique, tou de apwovizyone paGNEE RAILak fikse matche ak konsèy enstalasyon.
Kòm yon founisè Fastener ray pwofesyonèl,GNEE RAILka bay diferan estanda asye tren tankou GB, Ameriken, BS, UIC, DIN, JIS, Ostralyen ak Lafrik di sid ki itilize nan liy tren, trepye ak min chabon.
