極薄冷間圧延機における高速圧延技術および板厚制御技術

Technologies for High Speed Rolling and Control of Gauge in Cold Tandem Mill for Ultra-thin Gauge Strip

金 子 智 弘(Tomohiro Kaneko) 増田 博昭(Hiroaki Masuda) 竹澤 幸平(Kouhei Takezawa) 要旨 : ぶりきミルのような極薄専用冷間圧延機では,製品板厚の薄物化と板厚精度の厳格化にと もない,ますます高い生産性と板厚精度が要求されている。川崎製鉄千葉製鉄所第 1 冷間 圧延工場の第 2 冷間圧延機ではこれまで高プレートアウト性ダイレクト圧延油や耐摩耗性 ワークロールの開発により圧延潤滑性を改善してきた。この結果,2800m/min での超高 速冷間圧延が可能となり,生産能率が著しく向上した。また,ストリップ全長にわたる板 厚精度向上を目的にバックアップロールの高速用ローラーベアリングの適用としてミルモ ータのAC モータ化を行った。この結果板厚精度として定常圧延部で±1.0%,加減速圧部 で±1.5%の精度を達成した。 Synopsis :

High productivity and gauge accuracy are required of a tandem cold rolling mill that produces ultra-thin gauge strip, such as a tin mill black plate. Until now, the authors have improved lubrication for cold rolling by developing a new direct rolling oil and a Ti-enhanced work roll having high wear resistance for No.2 TCM of Chiba Works. As a result, it has been made possible to conduct rolling at an ultra-height speed, that is 2800m/min, and productivity has been remarkably improved. Furthermore, in order to achieve a major increase in gauge accuracy at high rolling speed cold tandem mill the authors applied a roller bearing to back up roll for high speed rotation and replaced mill motors with high response AC motors. As a result, the gauge accuracy during rolling has been improved to ±1.0% at a steady rolling speed and ±1.5% in acceleration and deceleration.
