Self-connecting vibration crystallizer ：
The overall structure is more compact and the size is much smaller than the traditional design, reducing the weight of the vibrating table system equipment.
The mold "copper tube, inner water jacket and mold upper flange" vibrates. The mold box itself, cooling water, vibrating table, and electromagnetic stirring coil are all fixed. Compared with the traditional design, the dynamic gravity is reduced by 95%, so the vibration frequency and vibration accuracy are greatly improved.
High-precision vibration can significantly reduce the depth of vibration marks on the billet surface, improve the surface quality of the cast billet, and increase the service life of the mold copper tube.
Low maintenance costs.
The vibration drive source is a servo hydraulic cylinder, which drives the vibrating arm to vibrate; the flexible hydraulic control system can change the vibration frequency and amplitude during the casting process to optimize the negative slip time and negative slip rate; at the same time, the control system can realize online selection vibration curve, such as sinusoidal, deformed sinusoidal and triangular curve and other non-sinusoidal vibration modes.
Introduction to the company's new technology "Direct vibration + high efficiency mold" high-speed technology and equipment

Billet high-speed drawing technology:
The high-speed billet solution is suitable for the section of 150-200 billet of ordinary carbon steel, and the high-speed range is 3.0-6.5 meters. It has technical and project cooperation with Danieli Company of Italy and Comcast Company of Switzerland:
1. Optimize the mold assembly, using grooved copper tube technology, fixed water gap diversion water jacket technology, etc.;
2. Extend the secondary spray cooling interval;
3. Adopt high pressure and high density nozzle arrangement form;
4. The tundish pouring nozzle adopts automatic flow control technology that changes according to the pulling speed;
5. Whole-process temperature measurement system for continuous casting billet;
6. Adaptive water distribution control system.
At present, the casting billet with 160x160 section has been realized, and the production speed can be stabilized at 4.5m/min. In the future, through continuous technical updates, a speed level above 5.0m/min will be achieved.
