Steel Manufacturing Processes and Techniques

The video tutorial covers the process of reducing the thickness of aluminum lingotes using hot rolling techniques, ensuring a smooth finish by removing impurities. It also details the production of modern axes from high-quality steel, including heating, molding, and cooling processes. Various metal bending techniques are explained, highlighting their applications in low-volume production. Finally, the video illustrates the cold imposition process used to create specific types of containers.
