Increasing the level of control and management of arc steel-smelting furnaces

Abstract

Abstract The urgent problems of modern steel-making devices are considered on the example of ASSF-90 arc steel-smelting furnace. The analysis of modern methods for controlling the parameters of arc steel-smelting furnaces is performed, the main shortcomings of the methods used are diagnosed. Laboratory studies of the parameters of arc steel-smelting furnaces were carried out, as a result of which the dependences of the temperature parameters of the furnace during different periods of melting were revealed. Based on the data obtained, an algorithm for controlling an electric steel-arc furnace has been developed and a computer program has been written. A project has been proposed for introducing the program into an existing SCADA system at one of the modern Russian electrometallurgical facilities.
