热连轧机的设定模型与试验研究

The setting model of hot strip mill and experimental research

为了使热连轧机的厚度控制系统满足较严格的厚度公差要求 ,新建了轧制力模型并引入了绝对值AGC。在轧制力模型结构中考虑了相变和累计应变对轧制坯料变形抗力的影响和厚度方向的温度分布。试验表明 。

A rolling force model was derived and an absolute value AGC was introduced to make thick control system of hot strip mill to meet stricter thick tolerance In the structure of rolling force model,both the influence of phase transition and accumulative total strain on deformation resistance of rolling slab and thermal distribution in thick direction have been considerate The experiment shows that the thick accuracy of hot rolling product is greatly improved
