厚度自动控制(AGC)是板带轧机保证产品厚度精度的重要手段,是国际上行之有效的现代化板带轧机必不可少的新技术。它主要分为电动机械压下和液压压下两种。前者在六十年代已广泛应用于冷、热轧板带轧机,而液压压
Automatic thickness control (AGC) is an important means of ensuring the product thickness accuracy of strip mills and is an indispensable new technology in the modern and effective strip mill in the world. It is mainly divided into two kinds of electro-mechanical pressure and hydraulic pressure. The former in the sixties has been widely used in cold and hot strip mill, and hydraulic pressure
