Jan 22, 2026
Ahlau railua hauj lwm raws li kev taw qhia tas mus li, muab qhov chaw ruaj khov uas ua kom muaj kev sib txhuam tsawg, kev sib tw zoo ib yam, thiab kev nyab xeeb ntawm lub tsheb navigation. Nws hardness, metallurgical muaj pes tsawg leeg, thiab dov profile tsim txiav txim siab nws hnav tsis kam thiab kev pabcuam lub neej.
GNEE RAIL muab ntau txoj kev tsheb ciav hlau kom ua tau raws li tag nrho cov qauv thoob ntiaj teb, suav nrog AREMA / ASCE 25–175 lb, DIN536 crane rails A55–A120, thiab UIC50–UIC60, nrog rau kev txhawb nqa tag nrho rau qhov ntev customized, rail fastening systems, ua ntej - kev sib dhos, thiab cov ntaub ntawv zoo.
Specifications ntawm cov khoom siv Railway
Railway taug qab cov khoom specifications tsom rau siab - carbon steel rau rails, sib npaug hardness (0.65-0.85% Carbon) thiab toughness (Manganese 0.7-1.4%), nrog nruj tswj ntawm impurities (P, S<0.04%) for strength and wear resistance, plus specific dimensions (weight/meter, height) and treatments like alloying (V, Cr) or heat treatment for high-speed/heavy-haul lines, all conforming to standards like UIC, AREMA, or DIN.
