System and method for rough cleaning an anode assembly WO2002068724A1 (en) * 2001-02-27: 2002-09-06: Pescale S. The causes, impacts and corrective actions vary from one potline to another as it will be illustrated in this paper. The combustion of the fuel takes place in. Söderberg cells use a single, continuous carbon-aceous anode, baked in the cell by heat generated from the cell. Since anode tracking systems are on the edge of being realized [ 1 ] that will link baked anodes to green anode data, several bulk parameters at the final control of. The apparatus includes a conveyor (10) for moving a row of side-abutting baked anodes (11) sequentially into alignment with an anode separating device (13) having a separator blade (26) extending downwardly from a support arm (25). It is a spherical tempered borosilicate (pyrex) tube with high vacuum (10 −6 Torr). The aluminum electrolysis industry continually and unavoidably produces hazardous solid waste in the form of carbon anode slag. It is used for the characterization of baked anode core samples []. Secondly, a current volatility detection method. Anode Cleaning Machines 17. These. e. Then, the paste is compacted in a press or a vibrocompactor to form green anodes. Also known as electrochemical polishing, anodic polishing or electrolytic polishing, electropolishing is especially useful. current efficiency 94 %, anode density 1. Anode Baking, Anode Rodding/Cleaning, Electrolysis are . 19 04:59:31 The company comply with the contract strict, a very reputable manufacturers, worthy a long-term cooperation. carbon anode is consumed in the pots. The process itself is very expensive, time consuming and ecologically unfriendly. Schematic transverse section of the pre-baked Hall-Héroult cell anodes are made from carbon materials, different only inAnodes for use in aluminium smelting are made by mlxmg different sizes of petrol coke with pitch and then forming the anodes. 5366 Fax: 250. In this system, the current was injected into the anode from the top through the stub holes and left the anode through a set of probes in contact with the bottom surface. The baked density of the anode is an important quality characteristic, as it may affect anode life. TOP quality anodes baked under optimal furnace design, with totally controlled firing system and clean emissions: more anodes, less costs, with maximum consideration. It was the “second”-generation “hot” cathode X-ray tube. Flue Wall Straightening Machines. [1]. electrical resistivity measurement has been applied to carbon anodes. In combination with robotic anode. e. Finally it has to be mentioned that anodes with good and uniform properties can only be produced with a well designed and well maintained furnace, equiped with an automatic process control system. Chemical, physical, and mechan-The production in the anode compartment of a gold-bearing slime, which can cause passivation of the silver anodes, must be periodically removed, creating materials-handling challenges. Recipe management system—automating processes related to making up anode recipes and formulations, storing and analyzing data on anode recipes and formulations (for various anode batches), including experimental (pilot) recipes, analyzing the final product’s parameters as a function of the recipe, and communicating with. For simpler anode system design, noise elimination and higher productivity, the invention is complemented with a particular distinctive feature that is also aimed at achievement of. Designed and Manufactured in Australia. The Impact of the Firing and Control System on the Efficiency of the Baking Process, Light Metals (2003) 589–594. Four-column frame load bearing guiding The guide mechanism of extrusion press is applied to HP-EVC series anode. 55 g/cm3,assuming constant normalised baked anode weight and anode life 24 days with 16 anodes in one pot, as shown in Figure 7. All sections of the plant are semi-automated and several free-steered diesel vehicles are used for material transportation.
