Analytical calculations carried out to determine the degree of heat recovery by a liquid melt depending on the electric mode and the residual height of the furnace slag. It was shown that despite the use of automation systems, the temperature semiproduct tapping does not always correspond to the one specified in the process documentation. In this regard, there is a period of “finishing”, which is carried out at lower voltage steps and with a minimum residual mass of slag on the surface of the melt. An increase in slag mass leads to a decrease in the “freeboard” value in the steel ladle after tapping, which, in consequence, can lead to its downloading during ladle treatment procedure, with the loss of expensive additional materials. Based on the analysis of the data obtained, options proposed for improving the degree of heat recovery of electric arcs during the “finishing” period by changing the electrical parameters at a fixed height of residual slag in the furnace.
