Ki kalite asye tren tren? - Konesans

Rail Steel yo se pati kle nan tren an mete nan de liy paralèl bay yon sifas kontinyèl, fiks ak nivo pou kouri nan tren yo.

Ki kalite asye tren tren?

Pwal tren yo fèt sitou ak bon kalite-, cho-woule mwayen-kabòn asye, ak adisyon espesifik nan Manganèz, epi pafwa chromium, vanadyòm, oswa niobyòm pou amelyore dite, rezistans mete, ak severite ka zo kase ki nesesè pou reziste chaj lou ak gwo vitès. Konpozisyon asye sa a bay severite ak rezistans esansyèl pou ray, ak sifas redi souvan aplike pou fòs siplemantè.

Konpozan kle ak pwopriyete:

Kabòn (0.7% -0.8%): Kle pou dite ak fòs.

Manganèz (0.7% -1.3%): Amelyore hardenability ak mete rezistans.

Eleman Alloying (Cr, V, Nb): Ajoute fòs ak amelyore pèfòmans nan kondisyon ekstrèm, nòt Railroad Track Pou Vann.

Tretman Chalè: Souvan aplike (tankou trempe ak tanperaman) rafine mikrostruktur la, ogmante fòs ak pwolonje lavi sèvis.

Diferan estanda pou tren asye

Estanda tren asye yo varye globalman, diferan nan nonmen (kg / m vs. lbs / yd), dimansyon (wotè, lajè), konpozisyon materyèl (nivo kabòn / manganèz), ak konsantre aplikasyon, ak gwo sistèm ki gen ladan Ewopeyen (EN / UIC), Ameriken (AREMA / ASTM), Japonè (JIS), ak Chinwa (GB / T) estanda, tout vize bay fòs, mete pou rezistans, pwa ak estabilite diferan nan tren ak anviwònman. gwo-trajè nan tren limyè.

Estanda entènasyonal kle yo

Ewopeyen (EN/UIC): Itilize kg/m (egzanp, 60E1 pou 60kg/m), ak pwofil espesifik tankou UIC 54, 60. Konsantre sou severite ak soudabilite (egzanp, C45E asye).
