In the prior art, the sector section 0 of the continuous casting machine adopts a structure that inner arc frames and outer arc frames are connected through side frames, each device is provided with a plurality of side frames, the side frames and the outer arc frames are connected through bolts (the number of the bolts is determined according to the length of the device, the number of the bolts is far more than 4, then the combined body of the combined outer arc frames and side frames is connected with the inner arc frames, and the number of the bolts is the same as that of the outer arc frames connected with the side frames).

The adjustment of the taper is accomplished by adjusting the number of shim packs as many as the opening degree or by directly adjusting the shim packs for each roller.
In the sector section 0 of the continuous casting machine in the prior art, side frames are arranged on the left side and the right side, so that when the arc is aligned on line, the line of sight can be completely blocked by a theoretical upper side baffle, the position of an on-line template cannot be seen, the arc alignment correction cannot be performed, and the problem in the prior art is that hand holes are formed in the side frames on two sides, even if the hand holes are formed, because the sizes of the hand holes are quite limited, great inconvenience is brought to the arc alignment and the adjustment on line. In addition, due to the side frames, when the equipment is in linkage debugging, the specific position of the dummy bar cannot be clearly observed by field personnel from the outside, and small trouble is brought to debugging work.
In the sector section 0 of the continuous casting machine in the prior art, the roller base is directly processed on the vertical plate, once the vertical plate is damaged, the vertical plate is difficult to repair, and the use requirement can be met again only by the complicated process of roller gaskets or overlaying welding.
