一、前言 热连轧带钢成品质量主要取决于带钢纵向厚度差。引起带钢厚度差的主要原因有: 1.轧件来料厚度的波动; 2.带坯的纵向温差。 在轧制过程中用自动调节辊缝的方法来尽量消除这些干扰作用的影响。 武钢一米七热连轧机带钢成品厚度公差要求在0.05mm之内。为了达到此要求,除在每一个精轧机架上均设有电动AGC系统外,在F_7机架上还设有液压AGC系统,在带钢
First, the preface The quality of hot rolled strip steel products mainly depends on the strip thickness difference. Caused by the strip thickness difference are the main reasons: 1. Rolling incoming material thickness fluctuations; 2. Longitudinal temperature difference with the blank. In the rolling process used to automatically adjust the roll gap method to eliminate these interference effects. WISCO one meter seven hot strip mill strip thickness tolerance requirements within 0.05mm. In order to meet this requirement, in addition to the electric AGC system on each finishing stand, a hydraulic AGC system is also installed on the F_7 stand,
