OPERATION OF AN OPEN-TYPE ANODE BAKING FURNACE WITH A TEMPORARYrnCROSSOVER

摘要

As part of the Puerto Madryn smelter expansion project, AluarrnAluminio Argentino has built and now operates an open typernfurnace designed with Rio Tinto Alcan AP Technology. Thernfurnace was built and put into service in two stages, each of whichrnconsisted of 34 sections and 2 fires. In order to allow the erectionrnof the second stage and the connection between both halves of thernfurnace, a method that had proved to be successful on otherrnprojects, was applied. A temporary crossover was used to connectrntwo sections at the end of the first stage. This paper describes thernexperience gained during the operation under these conditions andrnthe procedure and process control modifications that have beenrnnecessary to maintain the anode baking quality.
