ROLLING METHOD OF PLATE

摘要

A method for rolling a plate is provided to minimize variation of thickness of the plate by finely controlling pressure of a pressure changing unit using an operation panel and a load cell. A method for rolling a plate comprises the steps: installing a pressure changing unit which is independently operated from a slider to a body unit(S100); applying power to a plurality of electric elements installed in the body(S200); inserting a material between rollers which rotated on the body(S300); rolling the material on a roller(S400); supplying hydraulic pressure exerting oil to the pressure changing unit(S500); sensing pressure of the pressure changing unit using a load cell and displaying sensed pressure on an operation panel(S600); re-rolling the material which has been already rolled using pressure of the pressure changing unit(S700).
