A method that predicts in a real time wear amount of work rolls and A apparatus that predicts in a real time wear amount of the work rolls

摘要

The present invention relates to a method for predicting a wear amount of a work roll for rolling work in real time. According to the present invention, the method for predicting a wear amount of a work roll for rolling work in real time predicts a wear amount of a work roll for rolling work in real time, calculates roll torque of the work roll from a current value of a motor to rotate the work roll, measures the calculated roll torque (T) and a roll pressure force (F) from an effective radius (r) of the work roll, and predicts the maximum wear depth from the roll pressure force in real time based on proportional relation between the roll pressure force and the maximum wear depth of the work roll.
