Key Features: Heavy duty hydraulic rams make light work of pushing anodes through the BACM in a single stroke in each direction enabling complete discharge of all anodes. Power consumption is less than 0. - Baked Anode Cleaning Machine – Assembly Stage - Servicing the world, with a local focus; May 2016 - CeMAT 2016 12th to 14th July Come visit us at stand C26 - What is a Baked Anode Cleaning Machine (BACM)? We answer your questions; April 2016 - Position Filled: Automation Project Engineer; March 2016Then the anodes were baked over a range of temperatures (920 to 1,260 C) in order to evaluate the influence of this heat treatment on anode properties. Scrap rates of baked anodes between 0. A prebaked anode baking technology by utilizing smelting slags as filler comprises the steps that the smelting slags are smashed to a certain particle size and sieved according to the certain particle size, when an anode green-pressing is fed into a furnace, smelting slags particles are treated as the filler and are baked according to the regular prebaked anode. Originally installed at the former Alcan Aluminium Valais - Steg smelter in Switzerland in 2004, VHE's anode hole reamer is a pneumatically driven system. very different processes . com2. The procedure is widely used in preparing parts for. Baking Furnace. Electropolishing is an electrochemical finishing process that removes a thin layer of material from a metal part, typically stainless steel or similar alloys. For baked anodes, the resistivity and the number of internal defects were the lowest for the anode cooled by forced convection in air and the highest for the one cooled by free convection in air (Fig.
