摘要： A hot dip coating system comprises a bath of molten coating metal contained in a vessel having a strip passage opening located below the top surface of the bath. A metal strip is directed along a path extending through the strip passage opening and through the bath of molten coating metal, to coat the strip. An electromagnet is employed to prevent the escape of the bulk of the molten coating metal from the bath through the strip passage opening while permitting the strip to move along its path. Expedients are provided to reduce leakage of molten coating metal through the strip passage opening.

摘要： A method and an apparatus are provided for electromagnetic stirring during a continuous casting process, especially for casting a billet and bloom of medium and high carbon steels. The method and apparatus provide a higher surface quality of the ingot, reduce the entrapping of nonmetallic inclusions into the ingot, and suppress issues regarding central segregation and central porosity. The method provides an improvement in the stirring process from the meniscus to the crater end—and relates to in-mold stirring and stirring in a zone of secondary cooling and up to the crater end. The in-mold stirring is geared towards the suppression of meniscus disturbance, for submerged casting, in particular, the reducing of helical and axial velocity components of the molten steel, the lowering of the initial solidification point to avoid the touching of a shell edge with the slag ring, and a decrease of oscillation marks.

摘要： Device and corresponding method for the continuous casting of molten materials, comprising a vertical duct having the shape of a funnel made of refractory material for receiving molten material, and a second duct where the molten material is cooled off, the two ducts being set one on top of the other and being axially aligned. The molten material is injected into the channel, around a stretch of which electromagnetic means are set for generating magnetic forces on the molten material, the said means consisting of a plurality of windings of electrically conductive material and of a ferromagnetic core and may be electrically supplied to produce a magnetic flux along the direction of the channel, thus producing a set of forces acting on the molten material which are directed orthogonally with respect to the direction of the said magnetic flux so as to maintain detachment of the outer surface of the molten material from the walls of the channel.
