Abstract

The invention relates to the field of vibration detection, in particular to a portable crystallizer vibration amplitude and horizontal oscillation measuring system of a continuous caster, providing reliable evidences for technicians to regulate and maintain a crystallizer. The system at least comprises vertical displacement sensors, horizontal displacement sensors and a processing and analyzing unit and is characterized in that the vertical displacement sensors and the horizontal displacement sensors are distributed on a crystallizer vibrating platform; the crystallizer vibrating platform of the continuous caster vibrates at a frequency of 0.35-6Hz and the processing and analyzing unit synchronously acquires vertical vibration quantity and horizontal oscillating quantity signals of each distributed vertical displacement sensor and horizontal displacement sensor at the adoption rate being bigger than the vibration frequency of the crystallizer vibrating platform, and the processing and analyzing unit obtains the casting blank quality and the relation between the vibration amplitude and the frequency influence of the crystallizer vibrating platform of the continuous caster through processing and analyzing the vertical vibration quantity and the horizontal oscillating quantity. The system is beneficial to carrying out real-time reconstruction, record, analysis and judgment on the crystallizer vibration amplitude and horizontal oscillation, thereby providing the reliable evidences for the technicians to regulate and maintain the crystallizer.

Description

technical field [0001] The invention relates to the field of vibration detection, and is a portable continuous casting machine crystallizer amplitude and horizontal swing measurement system that provides reliable basis for technicians to adjust and maintain the crystallizer. Background technique [0002] Mold is continuous casting machine equipment, its function is to force-cool the high-temperature molten steel continuously injected into its inner cavity through the water-cooled copper wall, export its heat, make it gradually solidify into a shell with the required cross-sectional shape, and make it The slab whose core is still liquid is continuously pulled out from the lower opening of the crystallizer, creating conditions for its complete solidification in the subsequent secondary cooling zone. The main function of the crystallizer vibration device is to make the mold move along the outer arc of the continuous casting machine according to the given amplitude, frequency an...
