摘要（英）：

The invention discloses a magnesium alloy casting cooling system. The magnesium alloy casting cooling system comprises an upper cooling cavity formed in the upper portion of a crystallizer, a lower cooling cavity formed in the lower portion of the crystallizer, a first thermocouple, a second thermocouple and a control device. The upper cooling cavity is connected with an upper cooling medium pipeline, and the upper cooling medium pipeline is provided with an upper control valve. The lower cooling cavity is connected with a lower cooling medium pipeline, and the lower cooling medium pipeline isprovided with a lower control valve. The position, corresponding to the magnesium alloy solidification start point, of the first thermocouple is arranged on the wall of the crystallizer. The position, corresponding to the magnesium alloy liquid core terminal, of the second thermocouple is arranged on the wall of the crystallizer. The control device is connected with the first thermocouple, the second thermocouple, the upper control valve and the lower control valve. In addition, the invention discloses a magnesium alloy casting cooling method. According to the magnesium alloy casting coolingsystem, the technology is simple, cast magnesium alloy products are high in quality, and adaptability is wide.
