Abstract:
The investigation experience of Institute of Metallurgy of Ural Division of RAS shows that in order to estimate technological melting characteristics in arc steel-melting furnaces and ladle metallurgy units, it is possible to use electric arc itself, as its burning zone is essentially a technological process zone, because several important characteristics of technological process are reflected in arc burning conditions features. The Institute of Metallurgy of Ural Division of RAS developed and tested data collecting automatic system of bath conditions, based on parameters of electric conditions, which allow: assigning operating information about current stage of charge melting to staff of electric-arc furnace (end of basin cutting, moment of charge melting); the necessity of materials adding; estimating the degree of deepening electrodes into slag; estimating the metal and slag oxidity; on the base of which the staff is able to make decisions concerning interference into melting process; changing conditions of coal inflation; inserting slag-forming materials; changing level of voltage, etc. The Equipment of Institute of Metallurgy of Ural Division of RAS, apart from measuring circuit, includes analog-digital converter (ADC) and computer. We receive signals of electricity and voltage from the bus-bar of the short net of every stage. The system functions independently from regularly set furnace settings.
