Krupnyk O. The automated process control and generation of cold blast in blast-furnace ironmaking

This thesis research is devoted to the solution of scientific task - the energy efficiency improvement of blast-furnace process by searching new mechanisms and interconnections of the process of development and transportation of cold blast for its automation, which allows minimizing atmospheric emissions of compressed oxygen-enriched air through snort valves. For the purposes of the problem of analytical construction of regulators the system of subordinated pressure control and cold blast flow at the outlet of the gas transmission network was built based on a modified method of symmetry. New control algorithms of elements in a system of cold blast development were developed during the process connection / disconnection of air heaters for reduction of the operation time of snort valves. Keywords: system management, development of the blast, blast furnaces, the electromechanical transducer, steam turbine, blower, gas transport network, heater, engineering controls.
