The utility model discloses a roller type
electromagnetic stirring device with a braking function, the roller type
electromagnetic stirring device comprises a traveling wave roller, a braking roller and connecting seats, the two ends of the braking roller are respectively connected with the first end of the traveling wave roller through the connecting seats, the traveling wave roller comprises a main shaft, a traveling wave coil and a roller sleeve, the traveling wave coil is wound on the main shaft, and the roller sleeve is sleeved on the main shaft. The traveling wave coil generates a traveling wave
magnetic field after being electrified; the
brake roller comprises an outer cylinder, an iron core, an arc-shaped coaming and end covers, two ends of the arc-shaped coaming are hermetically connected with the end covers to form a
hollow cylinder, the iron core is fixedly mounted in the
hollow cylinder and is perpendicular to the outer cylinder, the cross section of the iron core is
waist-shaped, a
brake coil is wound on the iron core, and the
brake coil generates a brake
magnetic field perpendicular to the traveling wave
magnetic field after being electrified. The traveling wave rollers generate transverse thrust to stir an unsolidified
liquid core in a
casting blank, the braking rollers generate longitudinal braking force to buffer overlapped
impact of
molten steel circulation formed by the transverse thrust of the traveling wave rollers on the two sides, sufficient mixing of
molten steel and floating of inclusions are promoted, and
slag entrapment is prevented.
