Description

Technical Field

[0001] The utility model relates to the technical field of slag discharging for continuous casting ladles, and in particular to a vibration slag discharging monitoring device. Background Art

[0002] Continuous casting is continuous casting, which is an important part of the steel production process. The continuous casting process is the process of casting liquid molten steel into solid steel billets. The molten steel flows from the ladle into the tundish, and the molten steel flows into the crystallizer through the tundish. The billets of equal length are formed through a series of processes such as crystallizer cooling, fan-shaped segment cooling, straightening, and cutting. Therefore, the quality of continuous casting will directly affect the quality of later steel. In the process of casting from the ladle to the tundish car, when the casting is about to be completed, slag will enter the crystallizer along with the molten steel. The slag will not only cause the water inlet to be blocked and affect the continuity of casting, but the slag will also penetrate into the continuous casting billet, which will seriously affect the quality of the later hot-rolled and cold-rolled steel products. It can be seen that timely monitoring of the slag under the ladle is a key means to prevent slag from entering the continuous casting billet.

[0003] The most widely used system at present is the electromagnetic induction slag monitoring system. However, since the system requires the coil to be buried in the ladle, the ladle needs to be modified, and the investment and maintenance costs are relatively high. At present, the inventor has also applied a vibrating slag monitoring device in actual work, combined with a mid-package weighing system. However, there are some disadvantages in the use process, for example: the currently commonly used slag monitoring technology includes electromagnetic vibration slag measurement.

This fixing method requires the use of specific installation tools, which is inconvenient to use, and the bolt fixing method cannot guarantee that the monitoring device is completely in line with the mechanical arm during the vibration process, and it is difficult to ensure the accuracy of the test.

[0030] In this embodiment, the protective box is provided with a USB interface for connecting to an external host computer, and the signal input end of the USB interface is connected to the vibration measuring single chip microcomputer by a communication data line. The external host computer can be directly connected by using the USB interface. Based on this structure, the utility model can quickly transfer the data in the vibration measuring single chip microcomputer to the computer, which can not only output the data of the slag situation to the computer for long-term storage, but also facilitate the analysis and summary of the data on the external host computer at a later time. In addition, the protective box is fixedly installed with an audible and visual alarm 15, and the audible and visual alarm 15 is connected to the vibration measuring single chip microcomputer by a communication data line. An internal power supply (not shown in the figure) is provided in the protective box, and the internal power supply is connected to the vibration measuring single chip microcomputer and the audible and visual alarm 15 by a wire to power the vibration measuring single chip microcomputer and the audible and visual alarm.

[0031] Those skilled in the art should know that the vibration-detecting single-chip microcomputer may include a vibration sensor 13 and a vibration-detecting circuit board 14. The vibration sensor 13 is used to monitor the vibration parameters of the mechanical arm of the manipulator and transmit the vibration parameters to the vibration-detecting circuit board.

The storage is used to store the vibration data, analysis results and alarm information of the mechanical arm 11 during the working process, which is convenient for subsequent query and tracing. In order to ensure the safe operation of the internal circuit of the protective box, the vibration measurement circuit board 14 should use the STMF single-chip processor, a low-power, high-performance microprocessor as the control core, and be equipped with safety protection measures such as over-current protection and over-temperature protection.
