[0020] Please refer to Figures 1-3 As shown, a surface coloring flaw detection device for a continuous casting roll includes an electron microscope 1, an L-shaped frame 4, a first strip board 5, a cylinder, a uniform wiping soft block 7, a second strip board 9, a wiping soft block 10, a first oil cylinder 15, a second oil cylinder 16, a control cabinet 18, a guide rail 19, a guide seat 20, a rectangular frame 21, a speed reducer 22, and a driving idler 23. Two electron microscopes 1 are respectively installed on the same displacement mechanism, and the displacement mechanism is arranged inside one end of the L-shaped frame 4. The back surfaces of the first strip board 5 and the second strip board 9 are respectively fixedly connected to the corresponding parts inside the L-shaped frame 4 through cylinders 6. The front surface of the first strip board 5 is provided with a uniform wiping soft block 7, and a number of coloring agent spraying holes 8 are arranged on the surface of the uniform wiping soft block 7. The front surface of the second strip board 9 is provided with a wiping soft block 10, and a number of adsorbed powder spraying holes 11 are arranged on the surface of the wiping soft block 10. Two driving idlers 23 are symmetrically and rotatably installed inside the same rectangular frame 21, and the speed reducer 22 located on one side of the rectangular frame 21 is connected to the shaft end of one end of one of the driving idlers 23.

[0021] The electron microscope 1 is electrically connected to an external display through a signal line, and is used to clearly present the image of the surface condition of the continuous casting roll obtained by the electron microscope 1 on the display, facilitating the observation of defects at the coloring flaw detection location.

[0022] As Figure 2As shown, the bottom end face of the L-shaped frame 4 and the top of the control cabinet 18 are connected to each other through two symmetrically distributed second cylinders 16. The first cylinder 15 located at the top end of the middle of the control cabinet 18 is connected to the back of the rectangular frame 21. By extending and contracting the second cylinders 16, the electron microscope 1, the uniform wiping soft strip 7, and the wiping soft strip 10 connected through the L-shaped frame 4 can be lowered and approached the surface of the continuous casting roll placed on the two driving rollers 23.

[0023] As Figure 1 and Figure 2 As shown, a spray head is provided in the coloring agent spraying hole 8, and the spray head is connected to a pump body located in the coloring agent tank 14 through a coloring agent conduit 12; a spray nozzle is provided in the adsorption powder spraying hole 11, and the spray nozzle is connected to a feeding pump located in the adsorption powder tank 17 through an adsorption powder conduit 13, which can respectively complete the coloring of the surface of the continuous casting roll and the covering of the adsorption powder.

[0024] As Figure 1 and Figure 3 As shown, two guide seats 20 are symmetrically installed at the bottom of the rectangular frame 21, and the two guide seats 20 are respectively slidably connected to the two guide rails 19. One end face of the guide rail 19 is fixedly connected to the bottom of one side of the control cabinet 18. A controller, a pneumatic system, and a hydraulic system are provided in the control cabinet 18. By the first cylinder 15 being in the extended or contracted state, the connected rectangular frame 21 can move left and right along the guide rail 19 through the guide seats 20.

[0025] As Figure 1 As shown, the displacement mechanism includes a lead screw 3 and a moving carrier 2. The two moving carriers 2 are respectively threadedly connected to the reverse thread structures on both sides of the lead screw 3, and the two moving sliders are in sliding contact with the strip-shaped groove 401 on the L-shaped frame 4. The outer end face of each moving slider is fixedly connected to the back of the corresponding electron microscope 1. By rotating the lead screw 3, the two electron microscopes 1 respectively connected through the moving carriers 2 move from both ends to the middle.

[0026] When the present utility model is in use, under the action of the existing controller, each actuator is controlled to operate. The continuous casting roll is adjusted by the workshop overhead crane to be between the two driving rollers 23 and in rolling contact with each other. The reducer 22 is started to drive the driving rollers 23 to rotate, so that the continuous casting roll is in a state of rolling in place. The first cylinder 15 is operated to be in the contracted state to drive the connected rectangular frame 21 and its two driving rollers 23 to move directly below the two electron microscopes 1. The pump body placed in the coloring agent tank 14 is started to spray the coloring agent from the spray head located in the coloring agent spraying hole 8 onto the surface of the continuous casting roll through the coloring agent conduit 12. At the same time, the uniform wiping soft strip 7 is brought into contact with the surface of the continuous casting roll through the extended cylinder 6, which plays a role in evenly spreading the coloring agent on the surface of the continuous casting roll. After the coloring agent operation is completed, the cylinder 6 is reset, and the output of the coloring agent is stopped;

[0027] After 10 to 30 minutes, operate the other cylinder 6 to be in the extended state, bring the wiping soft strip block 10 made of absorbent paper into contact with the surface of the continuous casting roll, so that the coloring agent on the surface of the continuous casting roll is wiped clean. At this time, the cylinder 6 is in a slightly contracted state, so that the wiping soft strip block 10 is separated from the surface of the continuous casting roll. Then start the feeding pump placed in the adsorption powder box 17 to introduce the adsorption powder into the spray nozzle located in the adsorption powder spraying hole 11 through the coloring agent conduit 12 until the adsorption powder is sprayed and covered on the detected surface area of the rolling continuous casting roll. Since the adsorption powder can adsorb the coloring agent and penetrate into the defects to form a visible color reaction;

[0028] After the above operations are completed, start the second oil cylinder 16 to be in the contracted state and start the built-in motor to drive the lead screw 3 to rotate, so that the two electron microscopes 1 connected by the L-shaped frame 4 move down close to the surface of the continuous casting roll and gradually move from both ends to the middle, so as to observe whether there are color reaction parts representing defects under the electron microscope 1. At the same time, the electron microscope 1 presents the image information on an external display to achieve the effect of magnified observation;

[0029] In summary, it is possible to perform automatic coloring flaw detection on the continuous casting roll, and the roller surface treatment such as coloring agent and adsorption powder is labor-saving and time-saving. The electron microscope is used to approach and perform high-definition magnified observation on the coloring flaw detection area of the continuous casting roll, improving the accuracy of coloring flaw detection.
