Problems solved by technology

At present, most of the mold hydraulic vibration devices used in domestic slab continuous casting machines rely on foreign companies to provide, and there are many problems in use, such as the wear between the rolling unit and the guide plate causes the gap to increase, resulting in casting The depth and shape of the vibration mark of the slab are irregular; some equipment has a resonance phenomenon, which increases the deflection of the mold during vibration, resulting in a decrease in the surface quality of the slab, etc.

Abstract

The invention belongs to the technical field of metallurgy continuous casting, and particularly provides a hydraulic vibration system of a small square billet or small circular billet continuous casting machine crystallizer. The hydraulic vibration system comprises a vibration unit, a servo hydraulic unit and a control unit, wherein the vibration unit supports the crystallizer and is used for controlling the crystallizer to conduct arc or arc-imitation motion according to the arc radius set by a continuous casting machine, the servo hydraulic unit is used for controlling hydraulic pressure to be provided for a vibration servo hydraulic oil cylinder and enables the vibration unit to drive the crystallizer to vertically vibrate according to a given sine or non-sine curve and the control unit is used for controlling the vibration unit and the servo hydraulic unit. The hydraulic vibration system of the small square billet or small circular billet continuous casting machine crystallizer has the advantages that the structure is compact, the crystallizer can conduct the arc or arc-imitation motion according to the set arc radius of the continuous casting machine, the online vibration parameter adjusting function can be achieved, the vibration control accuracy is high, the deflection errors of the continuous casting machine crystallizer can be effectively controlled in the longitudinal direction and the transverse direction in the vibration process, stability is good, service life is long, the failure rate is low, and the requirement for modern production of high-quality steel in a continuous casting mode is satisfied.

Description

technical field [0001] The invention belongs to the technical field of metallurgical continuous casting, and in particular relates to a hydraulic vibration system for a crystallizer of a billet or billet continuous casting machine. Background technique [0002] In the continuous casting machine, the mold vibration system is an essential part of the continuous casting machine. At present, most of the mold hydraulic vibration devices used in domestic slab continuous casting machines rely on foreign companies to provide, and there are many problems in use, such as the wear between the rolling unit and the guide plate causes the gap to increase, resulting in casting The depth and shape of the vibration marks of the slab are irregular; some equipment has a resonance phenomenon, which increases the deflection of the mold during vibration, resulting in a decrease in the surface quality of the slab, and so on. Therefore, it is necessary to independently develop a practical and reli...
