FLATNESS CONTROL METHOD USING A FINE PASS ROLLING METHOD ABOUT ROLLING MATERIAL USING NSCR

摘要

PURPOSE: A flatness control method using a fine pass rolling method about rolling material using NCSR is provided to improve productivity and shorten the rolling pitch by preventing facility accident.;CONSTITUTION: A flatness control method using a fine pass rolling method about rolling material using NCSR are as follows. A rough rolling evaluates initial reduction rate of the current pass of the rolling material(S100). The rough rolling sets up the reduction rate range for obtaining a target flatness(S200). A minimum rolling torque is set up in current pass except final pass for maintaining final reduction rate(S300). The reduction material generates minimum reduction torque of the current pass(S400).;COPYRIGHT KIPO 2010
