Abstract: A method for containing a slab during continuous casting, including casting a slab along a casting axis, said slab having a predefined width, wherein the method provides a containment of the slab with a plurality of rolls, said rolls being disposed in pairs facing to each other, and defining a passage along the casting axis for the cast slab, wherein the plurality of rolls includes electromagnetic rolls provided with an electromagnetic stirrer which stirs the liquid contained in the slab.

Abstract: Apparatus for heating metal products, able to heat by electromagnetic induction at least one metal product positioned in a heating chamber and mobile in a direction of feed, in which said heating apparatus comprises one or more heating coils positioned in a ring around said heating chamber and said metal product to be heated; said one or more heating coils are positioned substantially transversely to the direction of feed of the metal product and are able to generate a magnetic field having a direction substantially parallel or coincident to the direction of feed of the product to be heated and directed in the same direction as said direction of feed of the product to be heated; said heating apparatus also comprises at least one heat shield positioned between said one or more heating coils and the metal product to be heated; said heat shield comprises walls provided with blocks of thermal and electric insulating material and positioned around the metal product to be heated and also comprises cooling pipes pos

Abstract: Thermal insulation screen transparent to magnetic flux, intended to isolate an electromagnetic inductor with a transverse or pseudo-transverse field, from the radiation of a heated product (1), the thermal screen being made up of a matrix of blocks (7) made of a thermally insulating material and of a plurality of tubes (8) cooled by the circulation of a fluid, these tubes being imprisoned in said matrix of blocks and the tubes and the blocks being held in place by a support. The screen includes, behind the blocks, heat-conducting means (10) placed so as to intercept the heat flux passing through the blocks, these conducting means being thermally coupled to the cooled tubes (8) for discharging the heat flux into the tubes.
