Abstract
The paper is concerned with the synthesis of the automatic control system based on the experimental statistical model of the gas-dynamic operating mode of a continuous furnace in the process of practical implementation of the energy-saving method of heat load distribution by the heating zones, when up to 40% of the total heat load of the furnace is supplied to the soaking zone. Planning and implementation of the complete active 25 factorials were considered for a four-zone continuous furnace under actual operating conditions. The paper describes the results of the plan implementation and the statistical appraisal of obtaining the results to develop adequate models of pressure distribution along the furnace working chamber in order to choose the most representative pressure take-off for the automatic control system of the gas-dynamic mode in the working zone. Implementation of the suggested method of pressure take-off made it possible, without any significant costs, to decrease the specific consumption of the fuel equivalent value by 1.7 kg/t when the automatic control of gas-dynamic mode of a continuous furnace is applied.
