Description

TECHNICAL FIELD

[0001] The utility model relates to copper alloy metal material processing field, concretely to emulsion and rolling oil dual -purpose rolling mill. BACKGROUND

[0002] In the field of metal material processing, rolling mill is a common equipment for pressing metal materials into various shapes and sizes. During rolling, lubricant is needed to reduce friction and wear, improve rolling efficiency and quality. The traditional emulsion rolling mill uses a water-based lubricant during rolling. The use of emulsion in metal rolling has a long history. However, with the progress of science and technology and the increasing awareness of environmental protection and the increasing demand for product surface quality, the shortcomings of emulsion have gradually emerged. Emulsion contains a large amount of water, which can easily cause metal surface rust and corrosion, thus failing to meet customers' requirements for material surface quality, and also increasing the wear of the roller and reducing the yield, thus increasing the production cost. In addition, the service life of emulsion is short and needs to be replaced regularly, which not only increases the production cost but also pollutes the environment. In order to solve these problems, rolling oil rolling technology is developed to solve the above problems. However, the traditional old rolling mill cannot be used for rolling oil rolling, and additional replacement of existing equipment is needed, which is costly and increases the production cost of enterprises. SUMMARY

[0003] The utility model discloses a rolling mill that can use both emulsion and rolling oil to solve the problem that the current rolling mill mostly uses emulsion as lubricant, which can easily cause metal surface rust and corrosion, but replacing the rolling mill with one that uses rolling oil is costly.
