Abstract

A hydraulic vibration device of a slab crystallizer comprises two identical hydraulic vibration units and a hydraulic servocontrol system; the two hydraulic vibration units are fixed on the two sides of the crystallizer; the vibration guide device of each hydraulic vibration unit is a plate spring-type guide device; plate springs are mounted on the two sides as well as the upper and the lower positions of a vibration frame; the hydraulic servo cylinder of a vibration generation device is arranged on a fixed frame; and the piston rod of the hydraulic servo cylinder is connected with the vibration frame through a connecting rod. The hydraulic vibration device is characterized in that one end of each plate spring is connected with the fixed frame; the other end of each plate spring of the piston rod of the hydraulic servo cylinder that passes the middle part is connected with the vibration frame; a pair of plate springs on the left and the right, and the connecting position of the vibration frame and the fixed frame are arranged in a staggered manner; a pair of plate spring on the upper side and the lower side, and the connecting position of the vibration frame and the fixed frame are arranged in a staggered manner. The hydraulic vibration device can realize a nonsinusoidal vibration curve of the crystallizer, and has the advantages of small volume, light weight, high strength, stable performance in service, enhanced overall rigidity, high kinematic accuracy, long service life, etc.; furthermore, the hydraulic vibration device can meet the requirement for the vibration frequency of the continuous casting technology.

Description

technical field [0001] The invention relates to the key equipment on the slab continuous casting machine production line of the steelmaking plant, which enables the crystallizer to implement regular reciprocating vibration according to the given amplitude, frequency and waveform. Background technique [0002] The purpose of crystallizer vibration is to facilitate "demoulding" and prevent the occurrence of breakout accidents caused by bonding between the billet and the copper wall of the mold during the solidification process. At present, the new slab continuous casting machines are all straight arcs, and the straight mold is conducive to the floating of molten steel inclusions, which is conducive to the omnidirectional symmetrical and uniform cooling of the casting slab in the mold, and can obtain good casting quality. [0003] There are many types of vibration devices for slab molds. Currently, the vibration devices used in slab continuous casting machines include mechanica...
