(594002) ELECTRODE AND ELECTRODE MANAGEMENT TECHNOLOGY FOR USE ON BASE METAL ELECTRIC FURNACES

摘要

The requirements determining the design of the Soderberg electrode columns used in base metal applications are different to those of other industries. There is a strong trend to position the contact shoes above the furnace roof in order to reduce the risk of water leakages directly onto the furnace bath. Tenova Pyromet has adapted its proven electrode column design for application on base metal electric furnaces based on these requirements. The design modifications implemented as well as considerations regarding the overall electrode-roof-furnace arrangement are discussed. Equally important is the management of the Soderberg electrodes to prevent over or under baking. Tenova Pyromet has developed the AutoFurn? furnace controller to not only optimise furnace operations, but to improve electrode management. An overview of the electrode management control philosophy implemented by AutoFurn? is provided, focusing on intelligent electrode regulation, slipping and baking.
