| Abstract: | To the problem that delay and over control exist when hot rolling bar shear in high speed cutting,product quality is influenced and production line speed is restricted.The principium of hot rolling bar shear controlled by T400,and the effect of speed set-point characteristic to load current are analyzed.The shear control method by re-setting the parameters is optimized.Practical application of the optimized shear control method shows that the accuracy and speed of hot rolling bar shear can meet the requirement of on-line process control. |
