It will be appreciated that the end of the stopper needle 2 facing the ladle 3 is located in the receiving chamber 10 when the leak is not repaired, and that it is not possible to observe whether the stopper needle 2 is aligned with the leak hole 33 when the housing 1 is mounted. The end of the stopper needle 2 facing away from the ladle 3 extends outside the housing 1. Therefore, the axial direction of the sealing needle 2 is determined by providing the positioning mark so as to align the sealing needle 2 with the leakage hole 33.

S2, the first end of the casing 1 is attached to the sidewall of the ladle 3, and the horizontal projection of the leakage hole 33 is located in the first through hole, that is, the casing 1 covers the first through hole. At this time, the leak hole 33 is closed by the refractory 4 in the housing chamber 10.
S3, the position of the housing 1 is adjusted so that the axial direction of the sealing needle 2 coincides with the laser beam. In this step, since the laser beam is aligned with the leakage hole 33, the alignment of the plugging needle 2 with the leakage hole 33 can be realized only by adjusting the central position of the housing 1 where the laser beam is aligned with the plugging needle 2. Specifically, the housing 1 is adjusted so that the laser beam is irradiated to the positioning mark of the occlusion needle 2.
