JUDGING METHOD FOR GENERATING SOURCE OF THICKNESS DEVIATION OF SEAMLESS STEEL PIPE

PURPOSE:To judge on line the generating source of thickness deviation of a seamless steel pipe, by measuring the change of rolling conditions continuously in rolling a pipe-material to analyze a wave form obtained from the measured result. CONSTITUTION:Rolling load signals, obtained only in rolling,...
