Quick-change type double-cylinder electro-hydraulic direct-drive crystallizer vibration device

Abstract

The invention belongs to the technical field of metal smelting continuous casting production equipment, and relates to a quick-change type double-cylinder electro-hydraulic direct-drive crystallizer vibration device. The quick-change type double-cylinder electro-hydraulic direct-drive crystallizer vibration device comprises a fixed frame, a vibration frame, vibration generation devices and a vibration guide device, wherein the vibration frame is arranged in the fixed frame, the two ends of the vibration guide device are connected with the fixed frame, and the middle of the vibration guide device is connected with the vibration frame; the vibration generation devices are arranged in the fixed frame, one ends of the vibration generation devices are connected with the fixed frame, and the other ends of the vibration generation devices are connected with the vibration frame; and the two vibration generation devices are arranged on the inner sides of the two opposite sides of the vibration frame correspondingly. According to the quick-change type double-cylinder electro-hydraulic direct-drive crystallizer vibration device, an electro-hydraulic direct-drive mechanism is adopted to provide power, an external driving device is not needed, the whole driving mechanism is integrated, the structure is compact, the two vibration generation devices are adopted to restrain vibration of the vibration frame, so that vibration of the vibration frame does not depend on an upper plate spring and a lower plate spring, and the influence of the upper plate spring and the lower plate spring is avoided; and accurate vibration is realized by controlling displacement of the vibration generation devices, and meanwhile, a foundation is laid for automatic control.

Description

technical field [0001] The invention belongs to the technical field of metal smelting and continuous casting production equipment, and relates to a quick-change double-cylinder electro-hydraulic direct-drive crystallizer vibration device. Background technique [0002] Mold vibration device is an important equipment in continuous casting machine. In order to prevent the molten steel flowing down from the tundish from sticking to the copper plate during the solidification process in the crystallizer to cause sticking, cracking or leakage accidents, and to facilitate the stripping, the crystallizer is driven by a vibration device to perform periodic vibrations according to the vibration curve. To change the relative position of the molten steel surface and the mold wall, at the same time, reduce the bonding by adding mold slag. For billet continuous casting, hydraulic vibration is generally used, including hydraulic vibration body and hydraulic station. The main disadvantage i...
