Problems solved by technology
However, in the above calibration method, the operation space for removing and installing the gasket between the bearing seat and the side panel is narrow, the operation is difficult, inefficient, and time-consuming. If the precision calibration of the pinch roll is not accurate, it will cause cracks on the surface of the billet, subcutaneous cracks, etc. A variety of defects, resulting in unqualified billet quality

Embodiment Construction
[0045] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.
[0046] This embodiment provides an arc calibration device, which belongs to the technical field of steel rolling, and uses the arc calibration device to calibrate the movable section frame 100 . Such as figure 1 As shown, the active segment frame 100 includes a side panel 101 and a pinch roller 102, a plurality of pinch rollers 102 are arranged at intervals on the side panel 101, and the fixed position of the pinch roller 102 relative to the side panel 101 is adjustable. Such as figure 1 with figure 2 As shown...

The invention belongs to the technical field of steel rolling, and in particular relates to an arc correction device and an arc correction method. Wherein, the arc calibration device includes a working platform and a flat reference part, and the working platform is used to carry the side panels; Align the inner wall of the reference piece. The invention also discloses a method for correcting arcs. The side panel is placed on the working platform; the leveling reference part is set on the working platform and covered above the clamping roller, so that the top of the clamping roller abuts against the leveling reference part the inner walls; finally, reattach the side panels to the movable segment frame. The arc calibration device of the invention is easy to disassemble and easy to use; the arc calibration method improves the efficiency of calibrating the clamping rollers.
Description
technical field [0001] The invention relates to the technical field of steel rolling, in particular to an arc correction device and an arc correction method. Background technique [0002] The curved continuous casting machine is also called the full arc continuous casting machine. The crystallizer of the curved continuous casting machine is arc-shaped, and the secondary cooling device is in a quarter of the arc. During the downward movement of the arc-shaped roller table, it is cooled by spray water until it is completely solidified. After fully solidified, the billet enters the straightening machine at the horizontal tangent point, and then cut into blooms. The curved roller table is also called the movable section frame, which is used to carry the bloom. Its cross section is rectangular. The movable section frame is composed of four panels, namely the outer arc panel, the inner arc panel and two side panels. Among them, each panel is provided with a plurality of pinch rol...
