A refractory guide member and a method for heating the refractory guide member by use of an inductor, where at least one collateral electromagnetic field located in a region spaced apart from the inductor is generated by the inductor. The mold part is made of an electrically conductive layer with several insulating interrupting slots for the controlled deflection of eddy currents from a main field generated by the inductor into a region spaced apart from the inductor.

A method and an apparatus for inductively heating a refractory shaped member provided with an internal space, particularly for a metallurgical vessel, enable as rapid, uniform heating of the shaped member as possible. An inner inductor is introduced into the internal space, the shaped member is heated from the interior by such inductor, and the inductor then is removed from the internal space.

A method of casting molten material into a strip-shaped product having substantially intended final dimensions that first supplies molten material into the interior of a vessel having a casting nozzle connected thereto. The nozzle is formed of a refractory ceramic material and has a passage extending therethrough from an inlet opening connected directly to the interior of the vessel to an outlet opening. The nozzle is oriented relative to the vessel so that the outlet opening is positioned at a location higher than the inlet opening. Molten material passes from the vessel interior directly through the inlet opening and into the passage until an upper level of molten material in the passage is the same as an upper level of molten material in the vessel interior and below the outlet opening. Solidification of the molten material is commenced in the passage, thereby forming solidifying material. The solidifying material is moved through the passage in a direction toward the outlet opening, during which the material further solidifies. The thus further solidified material is discharged from the outlet opening by imparting to the nozzle, and thereby to the material, ultrasonic vibrations including at least one vibration component in the direction toward the outlet opening.
