综述了我国镁合金双辊薄带连铸技术的发展现状，以及几种双辊薄带连铸技术在开发和应用中取得的新进展。镁合金水平双辊铸轧技术在我国已获得工业化应用。镁合金垂直双辊铸轧（VTRC）的铸轧速度可达30 m/min以上，其研究和发展才刚刚起步，显示出令人振奋的潜力。通过比较两种工艺的工艺特点，发现高温拉坯工艺的工艺稳定性更好，真空拉坯工艺的拉坯速度和冷却速度更快。这两种工艺生产的产品质量有待进一步提高和研究。
The development status of twin-roll strip casting for magnesium alloys in China was summarized as well as the new progress when several kinds of twin-roll strip casting technologies were developed and used. Horizontal twin-roll casting (HTRC) of magnesium alloys has attracted much attention and has been industrialized in China. Vertical twin roll casting (VTRC) of the magnesium alloys can reach a speed of higher than 30 m/min and its research and development are just beginning and exhibit exciting potential. By comparing the process characteristics of the two technologies, the process stability of HTRC for the magnesium alloys is better, and the casting speed and the cooling rate of VTRC for the magnesium alloys are higher. The quality of the products by the two technologies needs to be improved and further investigated.
