The difference and comparison of forged wheels and cast wheels
1. From the perspective of object shape transformation:

Casting a wheel is to liquefy solid metal, and then put the liquid metal without shape into a mold to get something of different shape (solid-liquid-solid).


Forged wheels are solids that turn one shape solid into another. That is, solids change from one shape to another at high temperatures (solid-solid).


2. In terms of focus:

Casting a wheel is the process of casting molten metal into a model to obtain a casting. The foundry major focuses on the metal smelting process and the control of the process during the casting process


Forged wheels are plastic forming in solid state, which can be divided into hot working and cold working. Such as extrusion, drawing, pier thickening, punching, etc. belong to forging.


3. In terms of molding speed:

Casting the wheel is a one-time molding, the molten liquid metal fills the cavity and cools, and pores are easily generated in the middle of the part.


Forged wheels are formed slowly, mainly by extrusion at high temperature. The grains in the part can be refined.


4. In terms of performance differences:

Cast steel is brittle in performance and cannot be heat treated.


Forged steel has a finer structure, good toughness and strength, and can be subjected to various heat treatments.

Advantages of cast wheels: low price, short production cycle; disadvantages: low strength, easy to shatter after severe impact; enough for family car owners who do not have too many requirements for control and pursue economical benefits.


Advantages of forged wheels: light weight, good heat dissipation, high strength, not easy to be crushed after impact, higher safety, strong plasticity, and can be customized at will; Disadvantages: slightly higher price, long production cycle; forged wheels are suitable for the pursuit of performance, control and individuality.

Strength of Railway wheel dimensions for Catenary and Track maintenance vehicles
