Hot and cold rolling are two fundamental metal processing techniques. Hot rolling involves heating billets to 1,100–1,250°C, softening the material and reducing deformation resistance by 70–80%. This allows for efficient, large-scale shaping with lower force requirements. Cold rolling, performed at room temperature, requires significantly higher rolling forces to achieve precise dimensional control. The process enhances grain refinement and mechanical strength, making it ideal for high-precision, high-strength products.
Hot - rolled materials, with a yield strength of 200 - 400MPa, are ideal for construction and shipbuilding. Cold - rolled ones, reaching 500 - 1200MPa, serve automotive, home appliance, and precision industries.
Today, the integrated "hot-cold-heat treatment" process has become the industry standard, with intelligent technologies driving continuous innovation.
