NOVELTY - Method involves preparing a piece of a metal plate to be rolled for rolling, or preparing multiple metal plates to be rolled for rolling and compounding. Water, oil and nano particles are mixed and performing high speed stirring and ultrasonic vibration treatment. The blank to be rolled metal plate or multiple metal plate group of the blank is cleaned into a vacuum heating furnace for heating. Heat treatment is carried out to a single layer or composite metal plate obtained by rolling, straightening, trimming, segmenting and making into metal plate finished product. USE - Nano lubricating method for improving surface quality of a corrugated roll hot rolled metal plate. ADVANTAGE - The service life of the roller can be prolonged. The surface quality of the metal plate can be improved. The problem that the metal plate corrugated roller hot rolling process in the shape of warp and surface quality is bad can be solved. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the nano lubricating method (Drawing includes non-English language text).
