Cold rolling mills are industrial machines used to process metal sheets and strips at room temperature. This method enhances the material's strength and surface finish by reducing its thickness through a series of rollers. The process is essential in producing high-quality steel and aluminum products for various applications. These mills operate by passing metal through a set of rollers, which compress and elongate the material. The result is a smoother and more uniform surface, making cold rolling mills crucial in industries such as automotive, construction, and manufacturing. The final products often include steel sheets, aluminum strips, and other metal components.
