Copper cold rolling mill is a kind of equipment used for cold rolling processing of copper plates and strips. Its features include high precision, high efficiency and versatility. Through the cold rolling process, the copper material can obtain a uniform thickness and smoother surface. It improves the strength and hardness of the material. Copper cold rolling mill is widely used in electronics, communications, construction and other fields for producing electronic components, conductive materials, building decoration materials and so on. There are many advantages on meeting different specifications and requirements of copper material processing and improving product quality and production efficiency. At the same time, the copper cold rolling mill also has an intelligent control system, which can realize automatic production and improve the stability and reliability of the production line.
