Problems solved by technology
Although the online detection system has strong processing capacity and can realize long-term monitoring of the crystallizer state, the disassembly and assembly of the displacement sensor is complicated, and the service life is relatively short in high temperature and humid working sites. In addition, the hardware cost of the equipment is high, the volume is large, Low integration and inconvenient use
However, there are large errors in manual detection methods, which have little guiding significance for actual steelmaking production.

The invention relates to a vibration detection device for a continuous casting crystallizer, which comprises a hardware system. The detection device is characterized in that the hardware system comprises an acceleration vibration sensor, a lower computer data acquisition card, an upper computer system control card and a touch screen which are sequentially connected. The detection device can accurately detect the amplitude value, the frequency and the vibration waveform deflection ratio of the vibration of the continuous casting crystallizer through the different mounting modes of the sensor. The system has simple and convenient mounting, convenient carrying and easy maintenance and achieves the purposes of plug and play when required and unplug and removal when not required. The detection device has good man-computer interface, realizes different requirements of different users through adjusting parameters and is easy to control and operate by operators.
Description
technical field [0001] The invention relates to the field of metallurgical industry, and more specifically relates to a detection device and a detection method for continuous casting crystallizer vibration data for molten steel continuous casting equipment. Background technique [0002] The crystallizer is the billet forming equipment in the steel continuous casting production, and it is the heart equipment and key equipment of the continuous casting machine. In iron and steel production, the vibration of the crystallizer enables the forced stripping of the slab; it is beneficial to the lubrication of the slab and eliminates the connection; it improves the surface quality of the slab. However, the choice of mold vibration parameters is related to the production of continuous casting slab and the surface quality of continuous casting slab. In order to improve the surface quality of continuous casting slabs, online detection systems and traditional manual detection methods ar...
