<p>PURPOSE:To control a rolling speed to a fixed value by adequately and automatically setting the maximum speed of a rolling mill constituting a continuous treating equipment. CONSTITUTION:A speed reference of an inlet side equipment 1 supplying material continuously, a speed reference of a middle equipment 4 treating the material supplied from this inlet side equipment 1 and speed references of rolling mills 7 of an outlet side equipment 6 which rolls and coils the material supplied from the middle equipment 4 are calculated based on the maximum speed set to each equipment and the speed references of the front and rear equipments are corrected in proportion to the respective material lengths of an inlet side looper 5 and an outlet side looper 10 which store delivered differences of the material between the equipments. A speed pattern through which a unit schedule period of the mills 7, the inlet side equipment 1, the middle equipment 4 and the outlet side equipment 6 display the respective maximum capacities is obtained and average speed calculating means 16, 17, 18 calculating the average value of the speeds of these equipments based on this speed pattern, a selecting means 19 selecting the maximum of the average values of these speeds, a maximum speed calculating means 20 calculating the maximum speed set to the outlet side equipment 6 by the selected average value are provided.</p> |
