[0021] The positioning bolt 3 of the example is slidably connected with the track window 2, and the positioning bolts 3 are distributed at equal intervals on the bottom surface of the side plate 5. The above structure design enables the side plate 5 to stably slide along the track window 2 to adjust the working position with the positioning bolts 3.

[0022] The side plates 5 are symmetrically distributed about the center of the workbench 1. The top view length of the side plates 5 is greater than 3 / 4 of the top view length of the workbench 1. The above structural design enables the side plates 5 to fit closely with the side of the hot-rolled strip over a large area, providing horizontal limit for hot-rolled strips of different widths.
