Problems solved by technology
At present, there are mainly two kinds of common vibration devices. One is a mechanical eccentric wheel vibration device driven by a motor. Quality; one is a hydraulic vibration device driven by servo hydraulic pressure. Its core feature is to use a double-acting hydraulic cylinder to realize the vibration of the crystallizer by controlling the oil pressure at both ends of the piston of the hydraulic cylinder and the displacement of the piston.
The hydraulic vibration device can realize various required waveforms, thus improving the continuous casting efficiency and the quality of the slab to a certain extent, but since the device is a contact vibration device, when the contact factor is not fixed, the vibration waveform will be unstable. It is impossible to further improve the quality of the slab, and it is difficult to achieve high-efficiency continuous casting

The invention relates to a non-contact electromagnetic vibration device for a continuous casting crystallizer and a method for using it. At the bottom and around the frame, the lugs are fixedly connected to the crystallizer. The fixed frame is a groove structure, and the shape of the groove matches the lugs; the armature fixed at the bottom of the lugs and the iron core set at the bottom of the fixed frame form an electromagnetic Vibration device; armatures with the same shape fixed around the hanging lugs and iron cores arranged around the fixed frame form an electromagnetic lateral positioning device. The advantages are: the use of electromagnetic force, under the action of the excitation coil, not only can complete the vibration signal of any waveform, but also can realize non-contact vibration, no additional rigid constraints on the mold, can avoid the influence of uncertain factors, and improve the quality of the slab . The electromagnetic lateral positioning device is used to ensure the stable and non-contact vibration of the crystallizer.
Description
technical field [0001] The invention relates to a non-contact electromagnetic vibrating device for a continuous casting crystallizer of metallurgical machinery equipment and a use method thereof. Background technique [0002] Continuous casting machine is an important equipment in steel production, and the mold is called the "heart" of the continuous casting machine. Therefore, the design and research of the crystallizer vibration device is one of the effective ways to improve the quality of continuous casting. At present, there are mainly two kinds of common vibration devices. One is a mechanical eccentric wheel vibration device driven by a motor. Quality; one is a hydraulic vibration device driven by servo hydraulic pressure. Its core feature is to use a double-acting hydraulic cylinder to realize the vibration of the crystallizer by controlling the oil pressure at both ends of the piston of the hydraulic cylinder and the displacement of the piston. The hydraulic vibratio...
