Q235B 55Q I-Beams Steel Rail Railroad Mining

I-shaped steel rails are a type of railway track with an I-shaped cross-section and are an important component of railway tracks. Its main functions and features are as follows:

1. Guide train operation: I-shaped steel rails can guide the train wheels forward, ensuring that the train travels along the predetermined track.

2. Bearing wheel pressure: The head of the I-shaped steel rail is in direct contact with the wheel and can withstand the enormous pressure exerted by the wheel, and transmit this pressure to the sleeper and roadbed.

3. Provide a continuous and smooth surface: I-shaped steel rails provide a continuous and smooth surface for the rolling of wheels, which helps reduce vibration and noise during train operation and improve ride comfort.

I-shaped cross-section

The cross-section of an I-shaped steel rail is I-shaped, mainly composed of three parts: rail head, rail waist, and rail bottom. This design gives the steel rails high strength and stability, capable of withstanding the pressure exerted by heavy-duty trains.

Rail head: narrow and thick, tightly fitting with the wheel rim, bearing the direct pressure of the wheel.

Rail waist: connects the rail head and rail bottom, with high bearing capacity and bending resistance.

Rail base: wider, with a large force bearing area, able to maintain the stability of the rail.
