Abstract

The invention belongs to the technical field of metallurgy, and relates to a multi-stage continuous casting crystallizer. The multi-stage continuous casting crystallizer comprises a crystallizer unit,a cooling unit for cooling the crystallizer unit and a vibration control unit for controlling vibration of the crystallizer unit. The cooling unit comprises a water supply pipe and a water return pipe. Through non-synchronous vibration control of a plurality of sub-crystallizer units, the friction force between a slab shell and a crystallizer copper plate is reduced, so that the targets of increasing the pulling rate and reducing the bleed-out probability are achieved.

Description

technical field [0001] The invention belongs to the technical field of metallurgy, and relates to a multi-stage continuous casting crystallizer. Background technique [0002] Continuous casting is the process of cooling liquid molten steel into a solid casting billet with a specific shape. The liquid molten steel flows into the mold through the immersion nozzle, and after cooling in the mold to form a shell with a certain strength and thickness, it is continuously pulled out for crystallization. , and continue to cool to a solid billet. In recent years, in order to achieve energy saving, emission reduction and production cost reduction, high-speed continuous casting technology has become one of the important trends in the development of the continuous casting industry. [0003] The difficulty of increasing the drawing speed of the continuous casting process is that at high drawing speed, the probability of breakout accidents in the mold area is high, and there are two reaso...
