Description

Technical Field

[0001] The invention relates to the field of hot-rolled seamless steel pipe manufacturing equipment, and in particular to a plug surface defect detection device. Background Art

[0002] In the production process of hot-rolled steel pipes, the plug (or top ingot) is a key tool used to support and guide the forming of metal tube billets. It is usually installed on the piercing head of the rolling mill to expand and shape the inner hole of the steel pipe and help maintain the size and shape of the inner hole of the steel pipe. However, in the process of rolling steel pipes, the falling of the plug will cause problems such as inner surface defects of the steel pipe, deviations in the inner diameter and wall thickness of the steel pipe, damage to the piercing machine and rolling mill, which seriously affect production efficiency.

[0003] Since the hot steel pipe is in a very harsh environment during rolling, the required equipment needs to be resistant to high temperature and corrosion. In addition, a large amount of dust and smoke will be generated during rolling, and a lot of water vapor will appear during the rapid cooling process. The harsh environment affects the operation of the equipment and the accuracy of the detection. The existing detection equipment has a single structure and function, and generally detects whether the plug has fallen off, but fails to take into account the problems of plug meat falling off and melting tip.

[0004] The patent publication number is CN115400982A, and the patent name is a prior patent technology of a steel plant head detection system. It specifically discloses "including a position detection trigger device, a high-speed camera device, an industrial control host and an alarm device; the position detection trigger device, the high-speed camera device, and the alarm device are all connected to the industrial control host in communication; the position detection trigger device is arranged at the front end of the high-speed camera device, and the high-speed camera device continuously shoots the preset position at a high speed with preset shooting parameters according to the start signal sent by the industrial control host, and transmits the obtained n pictures to the industrial control host; the head feature recognition model trained in the industrial control host recognizes the received picture and gives a conclusion whether there is a head feature in the picture; if there is no head feature in the picture, the industrial control host sends a trigger signal to the alarm device; the alarm device sends an alarm message to the outside according to the trigger signal of the industrial control host". The above patent technology is composed of two groups of cameras and one group of radars, resulting in a vertical installation of the frame, a single structure and function, imperfect equipment protection measures, etc., and it cannot be adjusted in all directions according to the head position.

[0005] The patent announcement number is CN204724591U. The patent name is a prior art of a punch head detection device. It specifically discloses "including a plug, a push rod and a plug detection block arranged at the front of the plug. The plug includes a nose, a perforating part, a rolling part and an anti-conical part in sequence. The nose is arranged at the front end of the plug, and the anti-conical part is connected to the push rod. A detection area is provided in the plug detection block. The detection area includes a front end detection area and an annular detection area. The front end detection area is a cylindrical hole that allows the nose to enter. A detection head that moves therein is provided in the front end detection area. The detection head is connected to an elastic part, and the elastic part is connected to a nose detector; a plurality of annular detectors are provided in the annular detection area, and the annular detectors are evenly distributed along the moving direction of the plug." The above patent obtains plug-related information through sensors, but is not suitable for high-temperature (above 1200°) rolled seamless steel pipe production lines. The production line works continuously, and after the plug is pierced, it needs to be cooled with water. Water vapor and smoke will cause unknown errors in the detector.

[0006] At present, in the production of hot-rolled seamless steel pipes, the equipment for detecting the falling of the plug has shortcomings such as single function and imperfect equipment protection measures. The damage to the plug itself during the rolling process will also cause the quality of the rolled pipe to decline. Most of the existing equipment uses traditional CCD cameras to take pictures and then process them by program to determine whether the plug has fallen. Or a ring detector is used to measure the plug information. Traditional CCD detection has poor anti-interference and cannot accurately detect the defects of the plug. It cannot eliminate interference factors such as high-temperature water vapor and smoke. The detector detection method is not suitable for high-temperature (above 1200°) rolled seamless steel pipe production lines. Since the production line works continuously, the plug needs to be cooled after perforation, and the cooling water vapor and smoke also cause unknown errors in the detector. Summary of the invention

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention arranges a rotating bracket, a rear roller, a front roller and an angle control mechanism on the plug detection support frame. Through the cooperation of the above structures, the plug detection system can be used to perform lateral, longitudinal and all-round rotation adjustment, and the detection angle of the plug detection system is continuously adjusted, which can improve the detection accuracy and better fit the existing production line without changing the installation position; the present application is flexible and light in installation, which is convenient for combination with the manufacturer's production line and does not affect the normal operation of the production line;

The heat insulation board frame outside the head detection part of the present application adopts high temperature resistant heat insulation material, which can cope with the high temperature and corrosive environment of the hot rolling zone. The design of the internal detection device is different from the traditional camera. Traditional cameras are mostly highly integrated with lasers and cameras, and the depth of field of the camera is too small to adapt to the hot rolling environment. In order to meet the detection requirements, the present application separates the camera and the laser to achieve free combination, which can better meet the depth of field range of thermal inspection and ensure that the camera has the best viewing angle. A cooling device is added to the laser to ensure the normal operation of the laser. In summary, the equipment of the present application itself has the advantages of high temperature resistance, corrosion resistance, anti-interference, and easy installation.

The camera 103 and laser sensor 101 in the detection box will be linked with the PLC of the production line. Before the top passes through, the laser and camera will be turned on to start collecting data.
