Abstract
To increase utilization of sulfur dioxide generated during blowing of copper-nickel matte in horizontal converters, a system of automatic control of gas mode of converter process was developed. The system consists of three hierarchy levels: at the lower level, the tasks of stabilization of technological parameters of matte conversion process determining gas mode of the unit are solved; at the middle level, the optimization of gas mode of individual converters is carried out in order to reduce gas emissions into the shop; at the upper, level the control of redistribution of gas flows of converters of the smelting shop in order to supply gases with maximum sulfur dioxide content to sulfuric acid production, the method of fuzzy system parameter identification is presented.
