Højhastighedsjernbanesvejseteknologi: Aluminotermisk svejsning, Tryksvejsning, Flash svejsning
Efterhånden som konstruktionen af højhastighedsjernbaneprojekter fortsætter med at blive dybere, landet har stillet skærpede kvalitetskrav til jernbanespor. Stålskinnen er en nøglekomponent i jernbanespor, og vælger...
Grøn støbning i gang: Sådan opnår du nul spildevand i smelteværket
Da den globale fremstillingsindustri accelererer sin overgang mod bæredygtighed, den traditionelle støberiindustri står over for alvorlige miljømæssige udfordringer. As a core foundation for rail transit equipment, the foundry industry consumes an average…
Hvad er mine elektriske lokomotivbremsesko?: Sikkerhedsgaranti for underjordisk lokomotivbremsning
In the deep mine tunnels, mine electric locomotives rumble and shuttle, carrying the safety of minerals and miners. When deceleration or emergency braking is needed, a reliable and efficient braking system is…
Fra støbejern til legeret stål: En århundrede lang udvikling af spormaterialer
Den september 27, 1825, et damplokomotiv bøvsede hvid røg, mens det langsomt trak en kulladet vogn langs Stockton til Darlington-linjen i England. This 32-kilometer-long line was not only the…
Jernbanebefæstelser: Sporsikkerhedens usynlige vogtere
Under the high-speed and fast-moving high-speed trains and on the winding and long-distance freight lines, there is a type of seemingly insignificant yet crucial component that silently undertakes the core mission of…
Stål arterier: En århundrede lang udvikling af jernbanespor
1. The Birth and Early Development of Railway Tracks 1.1 Railway Innovations During the Industrial Revolution When the Liverpool-Manchester Railway opened in 1830, it used fish-belly rails, each section only 4.5 meters…
Grundlæggende viden om jernbaner: Jernbanetransport
Railway transportation is a land-based mode of transportation in which locomotives pull trains along two parallel rails. Imidlertid, in a broader sense, railway transportation also includes non-wheel-on-rail methods such as maglev trains,…
