Acier moulé & Bogie en fonte: L'épine dorsale de l'innovation ferroviaire
1. Physical Structure: Le “foundation construction” of cast steel and cast iron 1.1 Cast Steel Frame: Stable Support Under Heavy Load The frame of the bogie is the core load-bearing structure. Taking…
Qu'est-ce que la coulée continue et le laminage dans les pièces ferroviaires?
Continuous casting and rolling is a process where the metal melt undergoes simultaneous rolling deformation during the continuous casting and solidification process, also known as liquid rolling or no-die rolling. This technology…
La tendance au développement intelligent et vert de l’industrie du moulage et du forgeage
Casting is the process of melting metal into a liquid state and pouring it into a mold. Then it cools and solidifies to form a shape. It is suitable for manufacturing complex…
Qu'est-ce que le rail sans couture de la voie ferrée?
Seamless rail of train track, également connu sous le nom de longue voie ferrée soudée, est une longue ligne ferroviaire formée en soudant ensemble des rails de longueur standard. It is an important new technology in track structure and has…
Fonte: Le gardien centenaire des carters de moteurs ferroviaires
1. Cast Iron Foundation Stones of the Steam Age 1.1 The Original Function of the Cast Iron Casing At the beginning of the 19th century, the power core of steam locomotives relied…
Liste de chemin de fer: Le “Colonne vertébrale flexible” dans les bogies
1.Compréhension de base de la traverse ferroviaire 1.1 Definition and Core Functions As the core load-bearing component of the railway vehicle bogie, the railway bolster is usually arranged in a transverse “je” shape or…
Quels types de patins en fer sont utilisés pour les fixations ferroviaires?
The iron base plates in railway fasteners are important components of the railway track system. They are responsible for supporting the rails, distributing the track load, and ensuring the stability and safety…
Moyeux de roues ferroviaires: Le “Pieds en acier” de l'exploitation des trains
The railway wheel hub, as the core component that directly contacts the train with the track, seems to be a simple “disc” structure. Cependant, it bears the entire weight of the train,…
Moyeux de roues ferroviaires: Analyse technique et adaptation des applications des procédés de forgeage et de fonderie
1. Special Challenges of Railway Wheel Hubs As core components of rail vehicles, railway wheels must operate reliably under extreme conditions. Their design must meet three key requirements: 2. Forging Process: Balancing…
What Is The Heat Treatment? Analysis Of The Seven Core Heat Treatment Processes
Heat treatment is a crucial step in the metal processing, which alters the internal structure and properties of metal materials through controlled heating, holding, and cooling to meet specific mechanical performance and…
La paire de roues minières est-elle spéciale?
The wheel set is the part of a locomotive or vehicle that comes into contact with the rails. It is composed of two wheels firmly pressed onto the same axle. The function…
Comparer aux rails droits et incurvés, Quelles sont les différences?
Although both straight and curved tracks are made of steel rails, their stress states are vastly different. Understanding this distinction is crucial for ensuring the safety, confort, and efficiency of railway operations.…
