Description

Technical Field

[0002] The main function of the three-roll mill is to roll metal materials to change their shape and size. The three-roll mill plastically deforms the metal material through the interaction of three rolls to achieve the required shape and size requirements. In the process of rolling bars and wires, the sizing mill can significantly improve the dimensional accuracy and performance stability of the product. For example, the use of the KOCKS three-roll sizing mill makes the round steel products more accurate in size and more stable in performance, which can efficiently meet the demand for steel in high-end automotive parts, bearing steel, oil extraction and other fields. In addition, the sizing mill also has the advantages of high deformation efficiency, small width expansion coefficient, and uniform force on the cross section of the rolled piece. The rolling process parameters can be intelligently matched through the remote control system to achieve precise control. The existing three-roll mill is used for rolling bars and wires.

In this process, the steel will be subjected to deformation force, which will cause a certain amount of shaking when discharging, which will cause the steel to deviate, especially when multiple rolling is required, which is easy to affect the rolling operation.
