Crane hnyav railyog ib qho tshwj xeeb, muaj zog steel khiav system tsim los pab txhawb thiab coj cov kev lag luam hnyav cranes (xws li nyiaj siv ua haujlwm gantry cranes hauv cov chaw tsim khoom lossis nkoj - mus rau - ntug dej hiav txwv cranes hauv cov chaw nres nkoj) rau cov kab rov tav txav, tsis zoo li cov qauv kev tsheb ciav hlau rau cov tsheb ciav hlau, muaj qhov tshwj xeeb profile (wide taub hau, thicker lub vev xaib) txhawm rau ua haujlwm hnyav, muaj zog, muaj zog thiab muaj kev cuam tshuam. nres- pib voj voog, ua kom ruaj khov, ruaj khov khoom tuav.
Dab tsi yog crane rails ua los ntawm?
Crane rails feem ntau yog tsim los ntawm siab - lub zog, hardened carbon thiab alloy steels, tshwj xeeb tshaj yog tsim rau hnyav loads, featuring siab manganese cov ntsiab lus (xws li U71Mn los yog U75VX qib) rau superior coj kuj thiab hardness, kom ruaj khov thiab durability nyob rau hauv xav tau kev lag luam ib puag ncig.
Cov ntaub ntawv tseem ceeb & Khoom
- High Carbon Steel: Muab qhov tseem ceeb hardness los tiv thaiv hnav los ntawm crane log.
- Manganese (Mn): Ntxiv los txhim kho hardness, lub zog, thiab hnav cov khoom, nrog cov ntsiab lus zoo li ntawm 1.1% mus rau 1.5% hauv qib zoo li U71Mn.
- Alloy Steels: Tsawg- alloy steels nrog cov ntsiab lus xws li Manganese (Mn) thiab Silicon (Si) txhim kho hnav thiab tiv thaiv corrosion.
- Killed Steel: Lub siab- steel zoo (feem ntau los ntawm qhib-hearth smelting) nrog tswj cov ntsiab lus roj, tiv thaiv qhov tsis xws luag xws li tawg thiab npuas kom txhim kho kev nyab xeeb thiab kev ua haujlwm.

Cov Qib & Cov Qauv
- U71Mn: Tus qauv siv dav dav rau cov crane rails (piv txwv li, QU70, QU80, QU100, QU120), nrog QU qhia lub taub hau dav hauv mm.
- DIN 536: Tus qauv European qhia cov qib kev tsheb nqaj hlau (xws li Qib 1, 2, 3) rau qhov sib txawv ntawm cov peev txheej.
Manufacturing & Tsim
- Kub Rolling: Cov txheej txheem siv los tsim cov ntsia hlau, ua rau lub ntsej muag du, ruaj khov.
- Cov Duab Tshwj Xeeb: Tsim los nrog dav flanges (soles) rau kev ruaj ntseg tiv thaiv ntsug thiab kab rov tav.
