Patent ID: 7984749

Claim:
A continuous casting mold assembly, comprising a casting mold; a water box mounted on the casting mold; permanent magnet means for generating a magnetic field that reduces the rate of deceleration of flow velocity of liquid metal in the mold in direction of flow of the liquid metal in the mold and including a plurality of permanent magnets arranged in the water box; and a carrier for supporting the permanent magnets and mounted on the water box, the permanent magnets having, in the direction of flow of the liquid metal in the mold, over a height thereof, different magnetic strengths or are spaced from each other by different distances for reducing magnetic field strength in the direction of flow of the liquid metal in the mold, so that to reduce the rate of deceleration of the flow velocity of the liquid metal in the direction of flow of the liquid metal; and means for displacing the carrier, together with the permanent magnets, relative to the mold for adaptation of the magnetic field strength to a desired flow velocity of the liquid metal in the mold.
