<P>PROBLEM TO BE SOLVED: To provide: a metal product manufacturing apparatus, which is inexpensive, is easy to maintenance, requires less running cost, and is easily installed; a metal product manufacturing method; and a rotary magnetic field generation system for stirring. <P>SOLUTION: By rotating a magnetic field generation device having a plurality of magnetic poles around a first axis along a pulling-out direction of a mold 30 so as to make different poles alternately line up around the rotary magnetic field generation system 10 arranged in the vicinity of an outlet of the mold 30 having an internal space for cooling up molten metal, the molten metal in a semifinished product is rotated around a second axis being parallel with the first axis by moving output magnetic force lines that come out from respective magnetic poles or input magnetic force lines that enter respective magnetic poles while they penetrate the molten metal in the semifinished product. <P>COPYRIGHT: (C)2013,JPO&INPIT |
