The number of the semi-circular steels used on the ship outfitting piece is large, the purchasing of the semi-circular steels in the market is difficult, the semi-circular steels can only be changed into two semi-circular steels by adopting round steels in corresponding specifications, and the whole round steel is unevenly heated in the cutting process, so that if the whole round steel is subjected to ordinary rigid fixation, the semi-circular steel after being cut is deformed no matter the volume of the semi-circular steel is reduced or the volume of the semi-circular steel is increased; under the condition that the volume is reduced, the round steel is easy to move inwards, so that the round steel is easy to cut and deform; when the volume becomes bigger, the round steel is easy to be extruded and deformed by the rigid supporting device. Generally speaking, the conventional fixing method can cause the round steel to deform in the cutting process, and the size and direction of the deformation or side bending are not controllable, so that the correction of the shape correction is needed. The increase of the straightening process not only restricts the production speed in terms of efficiency, but also causes instability in product quality.
