摘要： The present invention provides an electric furnace including: a furnace body; and a plurality of electrodes that are provided so as to hang down into the interior of the furnace body from a top section thereof. The raw material is heated and melted in the furnace body by energizing the electrodes and a molten material consisting of a slag and a metal is generated. The electric furnace is configured so that the overall heat transfer coefficient of a side wall of the furnace body is lower than the overall heat transfer coefficient of a side wall of the furnace body, the side wall coming into contact with a layer of the metal formed in a bottom layer, the side wall coming into contact with a layer of the slag formed in a top layer, and said layers being formed in the molten material due to gravity separation.

摘要： Disclosed herein are methods for producing an aluminum-scandium alloy comprising 0.41-4 wt % of scandium which can be used in industrial production setting. The method is carried out by melting aluminum and a mixture of salts comprising sodium, potassium and aluminum fluorides followed by performing simultaneously, while continuously supplying scandium oxide, an aluminothermic reduction of scandium from its oxide and an electrolytic decomposition of the formed alumina. Periodically, at least a portion of the produced alloy is removed, aluminum is then charged, and the process of alloy production is continued while supplying scandium oxide. Also disclosed is a reactor for producing an aluminum-scandium alloy pursuant to the methods described herein.

摘要： The invention relates to an induction crucible furnace and to a magnetic return element for an induction crucible furnace. The induction crucible furnace has a corresponding coil and a plurality of magnetic return elements, which are designed in the form of individual units arranged on the outer lateral surface of the coil with peripheral spacing. In order to guide the magnetic flux produced by the coil, the magnetic return elements each have an assembly consisting of a plurality of elongate individual elements of magnetically permeable material that are electrically insulated from each other and extend parallel to the furnace axis. Said individual elements consist at least partially of bars, which are electrically insulated from each other and the longitudinal axes of which extend parallel to the furnace axis. In this way, both eddy currents that hit the assembly from the radial direction and eddy currents that hit the assembly with a transverse component are minimized.

摘要： A silicon member and a method of producing the silicon member are provided. Cracking is suppressed in the silicon member even if the silicon member is used in a condition where it is heated. The silicon member 10 includes a coating layer 11 that coats a surface of the silicon member 10, wherein the coating layer 11 is composed of a product of silicon formed by reaction of the silicon on the surface, and a thickness of the coating layer is 15 nm or more and 600 nm or less. It is preferable that the coating layer is a silicon oxide film or a silicon nitride film.
