Telescopic crystallizer hydraulic vibration device

Abstract

The invention relates to a telescopic crystallizer hydraulic vibration device, which comprises a simulated arc-shaped crystallizer hydraulic vibration table used for providing vibration for a crystallizer and comprising a support structure, a vibration hydraulic cylinder arranged on the support structure, a movable arm arranged on the support structure, a first connecting rod arranged on the support structure, and a second connecting rod hinged between the first connecting rod and the movable arm; the movable arm, the first connecting rod and the second connecting rod can transmit vibration of the vibration hydraulic cylinder to the crystallizer so that the crystallizer can simulate arc-imitating motion. The hydraulic vibration table walking and positioning structure is used for walking and fixing the simulated arc-shaped crystallizer hydraulic vibration table, and the hydraulic vibration table telescopic structure is used for driving the simulated arc-shaped crystallizer hydraulic vibration table to move. According to the device, a hydraulic vibration table telescopic structure is adopted for driving, the whole vibration table can be moved away from a hot casting blank, high-precision instruments on the vibration hydraulic cylinder are repaired and maintained on line, faults such as oil leakage of a connector on the vibration hydraulic cylinder are processed on line, vibration stopping and production stopping are avoided, and the continuous casting production efficiency is guaranteed.

Description

technical field [0001] The invention relates to the technical field of continuous casting machines in the metallurgical industry, in particular to a telescopic mold hydraulic vibration device. Background technique [0002] The mold hydraulic table is the key and important equipment of the continuous casting equipment. Its function is to support the mold, provide the movement of the specified amplitude, frequency and waveform for the mold and the connected copper pipe, and realize the casting slab shell and the mold copper pipe. The relative movement between them plays the role of demoulding, preventing the billet shell from sticking to the copper tube of the mold, which will lead to cracking of the billet or steel breakout accidents, which will affect the quality of the billet. The existing electromechanical vibration table can only adjust the frequency during use, but cannot adjust the amplitude and waveform, and is gradually replaced by the hydraulic vibration table.

[0002] The mold hydraulic table is the key and important equipment of the continuous casting equipment. Its function is to support the mold, provide the movement of the specified amplitude, frequency and waveform for the mold and the connected copper pipe, and realize the casting slab shell and the mold copper pipe. The relative movement between them plays the role of demoulding, preventing the billet shell from sticking to the copper tube of the crystallizer, which will lead to cracking of the billet or steel breakout accidents, which will affect the quality of the billet

The existing electromechanical vibration table can only adjust the frequency during use, but cannot adjust the amplitude and waveform, and is gradually replaced by the hydraulic vibration table

However, it is difficult to overhaul and maintain the mold hydraulic table, especially the vibration cylinder of mold hydraulic vibration. There are displacement sensors, proportional servo valves, pressure sensors and other high-precision instruments on the belt and valve block of the vibration cylinder, and the working environment is harsh and the space is small. Close to the hot casting slab, located in the secondary cooling room, with high temperature and high humidity, once the protection or cooling of the vibration cylinder fails, it will cause the failure or failure of the high-precision instrument, and the direct result is that the vibration stops. If the vibration stops, the continuous casting machine Can only be shut down, waiting for processing after the shutdown
