Abstract

The computer model of temperature fields that emerge in water-cooled bimetallic hearth-level electrodes during the operation of arc steel-making furnaces of direct current was created. The model considers different structures of bimetallic hearth-level electrodes, the methods to connect their cooper and steel parts, and allows to choose optimum structure of hearth-level electrode for the specific conditions of metal smelting.
