Description

Technical Field

[0001] The invention relates to the technical field of slab flaw detection, in particular to a slab flaw detection device. Background Art

[0002] Subcutaneous defects in slabs (including inclusions and pores) are extremely harmful to the surface quality of rolled plates. These defects are crushed or deformed during the rolling process and exposed on the surface of the rolled plates, causing linear defects in the rolled plates, which greatly harm the surface quality of the rolled plates and subsequent coating and plating performance. Slabs are widely used in automobiles, shipbuilding, wind power generation, pressure vessels, high-rise buildings, oil pipelines, engineering machinery, hydropower projects, highways, bridge construction and other fields. There are two basic ways to strengthen the metal materials of continuous casting billets. One is to make defect-free complete crystals to make their strength close to the theoretical strength; the other is to try to prevent the movement of dislocations in defective metal crystals.

[0003] The current slab flaw detection equipment selects one position on the slab surface during flaw detection, and generates resonance between the vibrating instrument and the slab, thereby utilizing vibration detection to detect the fracture inside the slab. However, during operation, in order to realize the flaw detection of the slab more efficiently, one position on the slab surface is selected, which makes it difficult to judge the precise longitudinal direction of the fracture inside the slab, and the selected knocking points are insufficient, thereby reducing the accuracy of judging the fracture pattern inside the slab.

[0009] Preferably, the adjustment frame is rotationally connected to the bottom of the connecting plate via a shaft, and a driving motor is fixedly connected to one side of the adjustment frame.

[0010] Preferably, the adjustment frame is connected to each other through a connecting arm frame and a connecting frame, and a bolt shaft is provided between the connecting frame and the rotating seat.

[0011] Preferably, the connecting frame cooperates with the rotating seat to form a rotating structure, and the adjusting frame is bilaterally symmetrical about the symmetry center line of the connecting plate.

[0012] Preferably, transmission screws for movement and adjustment are installed on both sides of the bottom of the hanging seat, and a sliding structure is provided between the hanging seat and the hanger bracket.

[0013] Preferably, the side moving seat and the side guide rail are in sliding connection, and the linear motor seat and the linear guide rail cooperate with each other to form a sliding connection.

[0017] Compared with the prior art, the present invention provides a slab flaw detection device, which has the following beneficial effects:

At the same time, as the hanger moves, the linear rail and the linear motor seat cooperate with each other, so that the vibration recorder installed on the linear motor seat can move with the position of the hanger, and then cooperate with the slab flaw detection.

[0029] Specifically, the rotating motor 30 drives the ratchet 29 to rotate, and the inner wall of the toothed plate belt 11 has a serrated structure, so that the toothed plate belt 11 and the ratchet 29 form a meshing structure. At the same time, the interior of the connecting seat 12 is set to a tooth-like structure, which is conducive to the fixed connection with the toothed plate belt 11 through the meshing structure. In this way, it is convenient to use the toothed plate belt 11 to drive the connecting seat 12 to move, thereby realizing the movement and adjustment of the position of the hanger 13.
