MIXER Russian patent published in 2011 - IPC B22D11/49 

FIELD: process engineering.

SUBSTANCE: invention relates to continuous or semicontinuous casting. Proposed mixer comprises crystalliser 1, sprue tube 3 through which fused metal is fed into said crystalliser under metal meniscus 7, and, at least, one mixing device 4 with steel magnetic core with coil wound thereon. Magnetic core is located in the area of meniscus 7 at the distance varying from 50 mm above meniscus surface to 195 mm below said surface. Magnetic core length varies from 50% to 80% of crystalliser wider side length. Magnetic core is 240-280 mm high. Mixing devices 4 are arranged in asymmetry about crystalliser axial line wider sides.

EFFECT: melt flow stable speed and symmetric motion in meniscus region, resulting in lower turbulence, hence uniform growth of rim and nonmetallic inclusions in finished ingot.
