双辊铸轧薄带钢铸轧力计算公式及控制模型

Establishment of Rolling Force Formula and Process Control Model for Twin-Roll Strip Casting of Thin Steel Strips

在经典轧制理论和现代连铸理论相结合的基础上,推导出了铸轧力计算公式,并建立了一个非线性状态空间模型,描述双辊结晶器内的金属凝固和塑性变形.此模型可以作为双辊铸轧薄带钢过程铸轧力的实时在线控制模型.

Based on classic rolling theory and modem continuous casting theory, rolling force formula is deduced, and a nonlinear state-space model is established, which is to describe metal solidification and plastic deformation in twin-roll mould. The nonlinear model can be used in real-time on line control of rolling force and strip thickness of twin-roll strip casting.
