Clause is devoted to a frequency method of synthesis of technological processes on an example autogenous swimming trunks of sulphidic materials in furnace Vanjukova. The basic parameters of quality of management are resulted, revolting influences are described, transformation of a multivariate control system by complex processes to qvasisystem (to one-dimensional control systems) with the purpose of indemnification of indignations is made. The frequency method described in clause can be used for synthesis of control systems by other processes.
The approach to studying metallurgical processes by means of a method of planning of experiment is considered. With use 2 4 -factorial plans are investigated influence of parameters of loading of furnace Vanjukov on concentration of copper in stein. As varied variables the stream of sulphidic materials, stream of fluxes and stream of technical oxygen were considered. As a result of processing skilled data the equation of regress is received. Influence of separate factors, and also their joint influence is analysed.

A brief summary of the research and engineering work performed by professors, graduate students, and students of the Department of Furnaces, Control and Automation of Metallurgical Processes in 2000 is given. Two main directions of research activities were modeling of technological equipment for metal production and modeling of control systems for industrial metallurgical furnaces. In the first direction of research the following mathematical models were developed: converter conversion of smelting shop of Pechenganickel metallurgical plant; ore thermal smelting process; dissolution and liquation processes; waste water treatment using calcium hydrocarboaluminate. The technology of zinc-tin iron dust processing in a rotary kiln was also developed. A method of separating suspensions using LAROX PF press-filters was introduced. The second area of research includes works on development of spectral density method for synthesis of control systems with intermittent lag and on improvement of efficiency of manipulation of gas regimes in converters.
