摘要： An electrode case used to make a self-baking electrode that is consumed in a reducing arc furnace and the electrode made therefrom is described. The electrode case comprises an outer sleeve and a plurality of fins. The outer sleeve is divided into multiple sleeve sections made from a first metal, such that each sleeve section has an outer and inner surface, the multiple sleeve sections capable of being stacked together to form the outer sleeve. The plurality of fins is divided into multiple fin sections made from a second metal, such that each fin section is mechanically coupled to the inner surface of one sleeve section along its length and project radially therefrom along its width. Each fin section has an upper interface region, a central support region, and a lower interface region; the upper, central, and lower support regions having a lattice structure with at least 10% open area. Each fin section exhibits a constant volume of the second metal per unit length with the upper interface region of one fin section being capable of overlapping with the bottom interface region of another fin section.

摘要： The invention concerns a method for feeding fines or granules into a light-arc furnace (10) which consists in using a hollow electrode (24) provided with a feeding channel (38), preferably a hollow Söderberg electrode. A conveyor (40) introduces the fines or granules (12) into the feeding channel (38) so as to maintain the latter a column of material (42) whereof the lower end (44) is smelted in the molten metal bath (16).

摘要： The self-baking electrode suitable for use in an electric arc furnace comprises an elongated open ended electrically conductive casing for extending generally vertically within the furnace. A central core made of a heat conductive material is disposed within and spaced from the casing. A framework within is securing the central core to an inner surface of the casing for holding centrally the central core within the casing and for preventing an extrusion of the central core downward. The central core is surrounded by a carbonaceous electrode paste devised to cure into a solid electrode upon heating and to bond to the central core. This self-baking electrode allows the production of silicon metal in a Söderberg-type furnace without any modification to the usual slipping system or addition of another slipping system. An electrode according to the invention allows the same furnace to produce both FeSi of any grade and Si metal without any downtime between the gradual change from one product to the other and each time at the lowest electrode cost.

摘要： Provided is a self-baking electrode upper-end detection apparatus with which the upper end of a self-baking electrode can be detected automatically, accurately, and safely. The self-baking electrode upper-end detection apparatus (40) is provided with: a protection tube (50) that is disposed in an anchored state within an electrode case (20), and the lower end of which is positioned higher than the upper end of an electrode energizing section (30); a measurement tube (60) that is disposed so as to be inserted through the protection tube (50); and an air cylinder (70) for lowering the measurement tube (60) with a constant pressure, from the initial position thereof to where the lower end (61) of the measurement tube (60) hits a self-baking electrode (10) and stops. The air cylinder (70) is actuated so as to lower the measurement tube (60) until the tube stops, and an evaluation is made as to whether the stopping position of the lower end (61) of the measurement tube (60) is within a management range (R).
