在五机架冷连轧机的同步调速系统中采用下列公式来实现连轧机同步平滑的调速过程: Vi(m/min)=LS(‰)×ESi(‰)×Vnenni(m/min) (1)式中:LS(‰)—按S型曲线形状引导轧机的升降速,其值表示为最高轧制速度的千分比值,称为引导给定值LS。 ES_i(‰)—按秒流量相等原则分配给各机架的最高轧制速度设定值,其值表示占额定轧制速度的千分比值,称为单给定值ES_i
The following formula is used in the synchronous speed control system of five-stand tandem cold rolling mill to achieve synchronous and smooth speed regulation of the continuous rolling mill: Vi (m / min) = LS (‰) ESi (‰) × Vnenni (m / min) (1) Where: LS (‰) - according to the S-shaped curve guide the rolling mill speed, the value expressed as the highest rolling speed of the thousandth ratio, known as the guide given value LS. ES_i (‰) - The highest rolling speed setpoint assigned to each rack by the principle of equal flow in seconds, the value of which represents the fraction of the nominal rolling speed, referred to as single setpoint ES_i
