摘要： This invention relates to an electrode column and a method of determining the length of the electrode in it in an active furnace. The column is a Söderberg column including a mantel in which the electrode is movable in an axial direction by lower and upper slipping clamps which are movable relatively to each other by slipping cylinders. The method includes the steps of moving, with the slip clamps, the electrode in a downslip relatively to the mantel by means of the slipping cylinders and gravity and measuring the force required to move the electrode by means only of the upper slipping clamp against predetermined reaction forces acting against movement of the electrode and computing these parameters to determine the mass and so the length of the electrode relatively to the theoretical mass of the undamaged electrode at the time of movement.

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).
