Abstract
To give vibration to molten metal in a melt pool to enhance solidification efficiency of the molten metal. Substantially directly above meniscus 14 between molten metal 5 in a melt pool 4 and each of rolls, an AC electromagnet 15 is arranged over the entire length of said meniscus 14 so that magnetic flux runs substantially perpendicular to a surface of the molten metal. Above the AC electromagnet 15, a DC electromagnet 16 is arranged over the entire length of the AC electromagnet 15 so that magnetic flux runs substantially perpendicular to the surface of the molten metal. Under application of DC magnetic field by means of the DC electromagnet 16, an AC magnetic field is applied near the meniscus 14 between the molten metal 5 in the melt pool 4 and each of the rolls 1 and 2. As a result, induction current is generated in the molten metal 5 and high frequency vibration is applied to the molten metal 5 by Lorentz's force due to interaction between the induction current and the DC magnetic field.
