Product Description Features of cold rolling Cold rolling refers to the process of reprocessing hot-rolled materials at room temperature, which is mainly characterized by the following points: 1. High strength: Due to processing at low temperatures, the cold-rolled material has high tensile strength and yield strength. 2. High toughness: The metal grains deformed by external extrusion will become ... Shandong Zhengde Metal Manufacturing Co., Ltd Verified Supplierlicense Verified

Cold-rolled coils use hot-rolled coils as raw materials. During cold rolling, the rolled pieces are rolled below the recrystallization temperature. Generally, steel rolled pieces are rolled at room temperature. Silicon steel sheets with high silicon content have high brittleness and low plasticity and need to be preheated to 200°C before cold rolling. Since no heating is performed during the ...
