Description
This is a market dataset representing the consumption market in the region. It includes transportation of the product from the factory gate to consumption, with transport services calculated according to the regional transportation conditions for the product.
Activity Description
The production process of cold-rolled hard coils includes pickling and cold rolling of hot-rolled coils, covering energy consumption, material consumption, waste treatment, and environmental emissions required during the production process.
Process Description
Cold-rolled hard steel coil, also known as hard-rolled coil, is a special type of cold-rolled steel primarily used in electromagnetic applications such as the manufacturing of transformers and electric motors. This steel typically contains 2% to 4% silicon. The addition of silicon significantly enhances the material's electromagnetic properties, particularly by reducing eddy current losses and increasing electrical resistivity, which is crucial for improving the efficiency and performance of electrical equipment.

Technology comment
Using hot rolled steel coils as raw material, after pickling to remove the oxide scale, continuous cold rolling is carried out to produce hard-rolled coils. Due to cold work hardening caused by continuous cold deformation, the strength and hardness of the hard-rolled coils increase, while toughness and ductility decrease. Therefore, their stamping performance is relatively poor, and they can only be used for parts requiring simple deformation.
