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： A method and a system for monitoring clamping pressure exerted by a clamping cylinder to an electrode in an electrode slipping device which comprises an upper annular holderringand a lower annular holderring, each comprising at least one clamping assembly including a clamping shoe and clamping cylinder arranged in co-operation so that the clamping shoe is forced into pressure contact with the electrode and released from pressure contact with the electrode by the action of the clamping cylinder. The measuring system comprises a force sensor (30) mounted in connection with a pressing piece (22) that transmits the force created by the clamping cylinder to the clamping shoe. The force sensor can be a strain gage (30) mounted in a cavity (25) provided in the pressing piece (22) or a load cell mounted between the pressing piece (22) and the clamping cylinder.

摘要： A submerged arc furnace (10) produces foundry iron from scrap iron and steel sources where little or no slag is produced. Scrap iron or steel is fed into the submerged arc furnace (10) with a source of silica and a carbonaceous reducing agent. The scrap iron and steel is melted while simultaneously smelting the silica in the presence of the carbonaceous reducing agent. The amount of the silica source and carbonaceous reducing agent are added in an amount to selectively control the silicon and carbon content of the resulting foundry iron.
