Production of baked anodes from Anode baking furnace is performed through a continuous process with most important as well as costliest steps during. Main functions. We developed a special impact butt-cleaning system which has advantages of small volume, high capacity, low failure rate, low operation cost and can be used in the existing anode production line. To meet the new anode requirement, the baking cycle was accelerated to below 25 h from 26–30 h. 5 to 300HP. g. After rodding the baked anodes, the anode assemblies are used in the electrolytic cells for aluminum production. In fact, it helps keeps the lining in. It was the “second”-generation “hot” cathode X-ray tube. The R&D Carbon correlation relates key baked anode properties to overall reduction cell performance and in recent studies it was used to optimize the anode manufacturing process. Each anode in a pit has to reach a specific temperature overall in a certain time. It is then transported and placed into the electrolytic cell for operation. • Mass of waste tar collected. The factory has its own anode production with annual capacity of 130,000 tons of green anodes and 60,000 tons of baked anodes. C. Even in the presence of cracks and holes in the crust (for example,The baked density of the anode is an important quality characteristic, as it may affect anode life. 7. anode gas cleaning, by use of the so-called dry scrubbing method. The anodes are baked in pits that are usually separated from each other by fluewalls and headwalls made of dense refractory material. Our company is the first company in China to apply the guide mechanism of extruder to the anode vibration molding machine. Baked anode cleaning robot Shandong Hwapeng Precision Machinery Co. 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 baked quality can be found if baked anode weight and dimensions are measured. Originally installed at the former Alcan Aluminium Valais - Steg smelter in Switzerland in 2004, VHE's anode hole reamer is a pneumatically driven system. @ 350 °C nominal. has been dedicated R&D, manufacturing, marketing and sales of special-purpose machines and equipment applied in carbon iplants manufacturing green anodes, cathodes, graphite electrodes, graphite blocks, special graphite, carbon electrode paste. baked anodes and could lead, e. Abstract and Figures. The continuous anode of the Soderbergs is baked by the heat released from the cell itself. Th e quality of th baked anode s depend n gree anodeAfter, the laboratory scale anodes were produced and their green and baked densities, electrical resistivity, air and CO2 reactivities, and bending strength were measured. The baking stage is the most costly step of the anode manufacturing process and significantly affects the final anode quality. - high operational costs for extensive maintenance to clean equipment, ducts and FTC facilities. Call on (514) 687-7678. Baked anode quality is assessed by sampling cylindrical cores from less than 1% of the anodes produced weekly. 1. each side for this purpose. Finally, increasing fineness offines is an. 19 04:59:31 The company comply with the contract strict, a very reputable manufacturers, worthy a long-term cooperation. See Fig. close to that of a pre-baked anode - PAH emissions are reduced by over 50% 0 30 60 90 120 150. The anodes are stacked in pits where they remain fixed until the process ends. Carbon Baking Technology. References . kathy@hwapeng. , founded in 1936, is the first electrolytic aluminum plant in China. If they notice clear, gray, or blue gel or beads at the bottom of your water tank or anode rod, your aluminum anode rod is reacting with the high chlorine levels in. the green anodes are baked using large refractory furnacea up to a temperature 1200°C, of following an averageheating rate of 11°C/h. The evaporation and carbonization of the pitch in the baking process is the main source of the porosity in the baked anode [1]. This PT is a second-metals Article The Potential of Acousto-Ultrasonic Techniques for Inspection of Baked Carbon Anodes Moez Ben Boubaker 1, Donald Picard 2, Carl Duchesne 1,*, Jayson Tessier 3, Houshang Alamdari 4 and Mario Fafard 2 1 Aluminum Research Centre—REGAL, Département de génie chimique, Université Laval, Québec, QC G1V 0A6, Canada;. EB degassing at pressures >5. Advanced Dynamics engineers and manufactures mission critical material handling and processing systems for world leading primary aluminium smelters and secondary cast houses worldwide. This meant the anode length could be extended from 1600 to 1650 mm (baked anode dimension) without major investment in the APP (see Figure 1). During this. In this paper, the influence of the baking level and testing temperature on the thermomechanical behaviour of the carbon anode paste is investigated. The anodes under baking process are heated up to a temperature between 1050 °C and 1150 °C. Figure 1. • 3There is gain in anode reactivities if cokes of real densities lower than 2. The coarse porosity was investigated using X-ray computed tomography, the mid-range porosity using optical microscopy, and the finest porosity using mercury intrusion porosimetry. preparation, aluminium splashes, oversize steel particles or large. Previous work has shown how to overcome technical hurdles related to crack detection by using percolation-based. , Ltd. between the working shops . 656.
