The rodding station is the key installation of the system, as the access to the anode data is via the rod ID from here onup to stripping off of the spent anode; the dot-coding is surrendered as itCarbon anodes used in the aluminium industry were imaged through destructive and non-destructive testing (NDT) methods. The device is combined by respectively connecting and controlling an. The baked anode quality control strategy currently used by most carbon plants based on testing anode core samples in the laboratory is inadequate for facing increased raw material variability. Innovations include the SCAP-Rhodax® and Bi-Eirich processes, a high density anode forming solution, advanced baking furnace technology and a brand-new firing system. In stage 1 vanadium was introduced into the mixture composition of a dry coke charge from ordinary RF coke with a low vanadium content up to 350 ppm with UPNK (Petroleum Coke Calcining Unit) coke. The vibration molding machine is equipped with a vacuum system, which is simple in structure, easy to maintain, accurate in. be eliminated and corrosion inhibited in all sea water circulating systems. Both the green and baked anodes were characterized. VHE's baked anode cleaning system removes coke from anode holes and cleans all surfaces and chamfers. Technical Performance 1. This may be due to the effect of fine coke particles in anode on the. At the beginning of 2006, it joined Chalco and became a wholly-owned subsidiary of Chalco. Thus, the production of high-quality anodes depends, among others, on the efficient control of their. The baking was stopped at different temperature for each anode (200°C, 300°C, 400°C, 600°C, 800°C and 1050°C). HP-H(H)KC-SG Series Heating Kneading Cooling System for Special Graphite; HP-MDC Series Pulse Bag Filter;Results of introducing vanadium into molten aluminum through baked anodes are presented for thirteen month observation period (Fig. 44 tons of carbon is consumed and. The anodes are stacked in pits where they remain fixed until the process ends. high baked density for long anode cycle time and a low . 1 μΩ·m as the pitch/coke ratio was increased from 16 to 18/100. During the baking process, the anode undergoes complex physicochemical transformations. comDeep learning camera will take photos of anode blocks, after cloud processing and 3D imaging, it will send the three-dimensional coordinates of anode blocks to the robot, then the robot will clean anode block surfaces, stub holes and flutes, dust collecting device will take packing coke out while the robot cleaning stub holes. The plots confirm that the anode closer to the grounding system (i. The SER of the anodes experienced reduction by 26. In the last years, coke quality has been deteriorating throughout the world. The anode cover material must not introduce any metal contamination, and hence a mixture of alumina and recycled electrolyte is used. using slotted anodes in aluminium production cells is an easy and powerful prediction. 5 million tons per year []; around 0. Suitable for -40. are applying slotted anode technology to en-hance performance and to achieve economic and production improvements. 10 From baked anode properties, we estimate that this sort of preheating would require roughly 0. AIV-CS Baked anode cleaning robot is an artificial intelligent polishing robot which is developed by our company aiming at harsh work environment during cleaning and. Gases from pots are drawn off and treated in a dry scrubbing system before release to the atmosphere. To find out root causes behind the sub-standard baking, performance analysis of Anode Baking Furnace (ABF) was carried out. (2. metals Article Crack Detection Method Applied to 3D Computed Tomography Images of Baked Carbon Anodes Donald Picard 1, Julien Lauzon-Gauthier 2, Carl Duchesne 2, Houshang Alamdari 3,*, Mario Fafard 1 and Donald P. System. very different processes . Alumina is used in the scrubbing process. 1. In the lab, it is possible to produce anodes under different conditions and with or without specific defects, and the study of these anodes allows the verification of SERMA for its. In addition, the change in the resistivity of the anodes produced with biocoke modified using A(1) and A(3) was quite small, both for green and baked anodes. 8 a and b). 01. 5. Getting started; Baked Anodes Cleaning System; Baked Anodes Cleaning System - China Manufacturers, Suppliers, Factory. Full size image. System for recovering anodes from. Reduction cell operation in primary aluminum production is strongly influenced by the properties of baked anodes. The baked portion of the anode extends past the steel casing and into the molten electrolyte. This excess carbon consumption is partly due to the anode manufacturing processes. The powder was dried in . High quality baked carbon anodes contribute to the optimal performance of aluminum reduction cells. The oven enclosure contains a steel tube acting as a pyrolysis chamber, having a length of 1030 mm and a diameter of 100 mm. Baking Furnace – Automatic stacker cranes, cleaning machines, lifting, turning and positioning devices as well as heavy-duty roller conveyors and grouping conveyors increase throughput and productivity. From seals to expansion joints to precast refractory shapes to thermocouples, Pyrotek offers an extensive range of products and.
