Abstract

The invention relates to a non-contact electromagnetic vibration device of a crystallizer for continuous casting and a use method. The non-contact electromagnetic vibration device comprises suspension lugs, armatures fixed to the bottoms and the peripheries of the suspension lugs, iron cores with magnet exciting coils wound externally and fixed frames, wherein the iron cores are arranged on the bottoms and the peripheries of the fixed frames, the suspension lugs are fixedly connected to the crystallizer, the fixed frames are of groove structures, and the shapes of grooves are matched with the shapes of the suspension lugs; the armatures fixed to the bottoms of the suspension lugs and the iron cores arranged on the bottoms of the fixed frames form the electromagnetic vibration device; the armatures of the same shape fixed to the peripheries of the suspension lugs and the iron cores arranged on the peripheries of the fixed frames form an electromagnetic lateral locating device. The non-contact electromagnetic vibration device has the advantages that vibration signals of any wave shapes can be completed under the effect of the magnet exciting coils through the electromagnetic force, non-contact vibration can be realized, additional rigid constraints on the crystallizer can be avoided, the influence of uncertain factors can be avoided, and the quality of casting blanks can be improved. The crystallizer can be stable and free of contact vibration through the electromagnetic lateral locating device.

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
