Rail Wheel Factory Process Charts

Large semi-finished blocks of steel used in manufacturing.

The process of cutting steel billets to specified dimensions.

The specific dimensions of the cut billet: 287 X 300 X 343 mm.

Heating the billet in a Rotary Hearth Furnace at 980-1050°C.

A furnace design used for uniform heating of materials.

The process of shaping metal using compressive forces, typically from a forging press.

A cutting process using high propane gas for precise metal shaping.

An air-cooled area used to remove internal stress from forged materials.

A heat treatment that produces a uniform fine-grain structure in metals by heating and cooling.

A process of marking metal with numbers for identification or tracking.

A machining process where a cup-shaped profile is created, often performed on a journal orca.

A non-destructive testing method using high-frequency sound waves to detect flaws in materials.

A process of cutting and shaping materials using a Computer Numerical Control lathe for preliminary shaping.

A rapid cooling process using polymers after heating; often applied to loco axles for hardness.

A machine used to shape the outer surface of cylindrical objects for accuracy.

Internal cooling process to control material properties during heating.

Heat treatment that improves toughness by reheating metal after hardening.

Special purpose machine used for drilling and tapping processes in metalworking.

A finishing process that creates a smooth surface by polishing.

A computer-controlled process for precisely shaping and finishing materials.

An area or equipment used to accurately measure dimensions of components.

A non-destructive testing method for detecting flaws on ferromagnetic materials using magnetic fields.

A method that uses high-frequency sound waves to detect imperfections inside materials.

A measure of material hardness characterized by indentation diameter from a steel or carbide ball under a specific load.

A non-destructive testing method using high-frequency sound waves to detect internal defects in materials.

A test to assess distortion or warping in materials or products under specific conditions.

A surface treatment process that improves material properties through controlled deformation by shot particles.

The last assessment performed on a product to ensure it meets all specifications and quality standards before delivery.
