As a kind of strip Composite Cold Rolling Mill, the Stainless Steel Composite Mill has a more sophisticated and efficient working principle. During the cold composite process, the metal strip is rolled at room temperature, which requires the rolling mill to have higher precision and control capabilities. The Compound Mixing Mill will first pre-treat the metal strip, such as surface cleaning, deoxidation layer, etc., to ensure the cleanliness of the composite interface. Subsequently, two or more layers of metal strips of different materials are fed into the working area of the rolling mill through a precisely adjusted roller system. Under the strong force of the rollers, the metal strip undergoes plastic deformation, while the small gap between the rollers ensures that each layer of metal can be tightly combined without generating excessive internal stress.
