Embodiment Construction
[0061] In order to better understand the above-mentioned technical solutions of the present invention, the following further describes in detail with reference to the accompanying drawings and embodiments.
[0062] The control method for improving the rolling rhythm of a rough rolling mill of the present invention is used for figure 1 The control of the rolling rhythm of the roughing mill of the hot rolling production line is shown. The roughing mill includes a first stand R1 and a second stand R2, and several sets of roller tables Gx between the first stand R and the second stand R2, in Figure 4 ~ Figure 9 In the illustrated embodiment, X=1-8, and there are 8 sets of roller conveyors. The processed one or two slabs Bx (x=1 or 2), after rolling at least one pass in the first stand R1, are transferred from the first stand R1 to the first stand R1 through each set of roller tables G1 to G8 Two racks R2, and rolling m passes in the second rack R2 back and forth, where m is an odd ...
