PROBLEM TO BE SOLVED: To provide a continuous casting method for magnesium molten alloy which secures uniform cooling and thickness of a solidified shell in a mold so that a high quality cast piece free from cracks and irregularities can be obtained. SOLUTION: In the continuous casting method for molten magnesium alloy, a heating element 4 and a temperature measuring instrument 5 are arranged across the width of a mold 3 near a meniscus. The heating value of the heating element is adjusted on the basis of the measured value of the mold temperature and the temperature of the molten magnesium alloy 8 near the meniscus is controlled to the melting point of the alloy or higher. It is preferable to control the temperature of the inner surface of the mold near the meniscus to the melting point of the alloy or higher, in order to control the temperature of the molten magnesium alloy to its melting point or higher. This continuous casting method has a great effect in the case of using the mold of which the ratio of its thickness to its width is 1/10 or less. COPYRIGHT: (C)2004,JPO&NCIPI
