摘要： After molten metal has been poured from a ladle 6 into a converter, metal 6b adhering to the ladle 6 is dropped into the ladle 6 on-line, and molten metal is poured from an electric furnace into the ladle 6 into which the metal 6b has been dropped. As a result, the metal 6b is melted and is recovered as a material.

摘要： A load current value I of a motor (4) rotationally driving an impeller (3) is read out when the impeller (3) is rotated at a predetermined set rotational speed X 0 , and the rotational speed of the impeller (3) is increased so that the load current value I becomes equal to or larger than a threshold value I 0 when it is determined that the load current value I is smaller than the predetermined threshold value I 0 .
