Embodiment 1

[0033] Such as Figure 1-2 As shown, this embodiment provides a dual-source vibration device for a continuous casting mold, including a planar linkage mechanism and two power devices. The planar linkage mechanism includes a transmission mechanism, a rocker 5 and two cranks 1. The transmission mechanism includes A crossbeam 3, an output rod 4 and two connecting rods 2, a power device is used to drive a crank 1 to move, the upper end of each crank 1 is hinged to the lower end of a connecting rod 2, and the two ends of the crossbeam 3 are respectively connected to the two connecting rods 2 The upper end of the output rod 4 is hinged to the upper surface of the beam 3, the upper end of the output rod 4 is used to be hinged to the crystallizer vibrating table, one end of the rocker 5 is hinged to one side of the transmission mechanism, and the other end of the rocker 5 is connected to the The first base 6 on the frame is hinged.

[0034] In this specific embodiment, the power devi...

Embodiment 2

[0047] Such as image 3 As shown, the installation position of the rocker 5 in this embodiment is different from that in Embodiment 1. Specifically, the end of the rocker 5 away from the first base 6 is hinged to the output rod 4, and the hinge point of the two is located at the output rod 4. In the middle part, the output end of the output rod 4 indirectly pushes the crystallizer 7 fixed on the second connecting rod 9 to vibrate through the connecting rod mechanism.

[0048] It can be seen that, in the continuous casting crystallizer dual-source excitation device provided in the present invention, the two power devices rotate in one direction and move at the same angular velocity to respectively make the two cranks 1 realize the rotary motion, and the motion of the two cranks 1 is passed through the transmission Mechanisms are synthesized to push the crystallizer vibrating table to vibrate. Compared with the hydraulic cylinder shock wave driving device, not only can realize ...

Description

technical field [0001] The invention relates to the field of continuous casting, in particular to a dual-source vibration device for a continuous casting crystallizer. Background technique [0002] Continuous steel casting is the core link of steel production at present. During the process of pouring molten steel into the crystallizer, the mold must vibrate according to certain rules to ensure the lubrication conditions between the casting slab and the mold, thereby preventing the mold from forming a gap between the mold and the new slab shell. A steel breakout accident caused by bonding between them. With the in-depth understanding of various complex physical mechanisms between the slab and the mold, non-sinusoidal vibration is recognized as the optimal waveform for high-efficiency continuous casting. Therefore, the development of advanced non-sinusoidal Driving equipment has always been a hot topic in engineering circles at home and abroad. [0003] For molds such as squ...
