POSITION REGULATOR OF ELECTRODE OF ELECTRIC ARC STEEL SMELTING FURNACE

摘要

FIELD: metallurgy.;SUBSTANCE: invention refers to electrothermics, particularly to automated position regulators of electrodes of electric arc steel smelting furnaces. According to the invention for each phase of the electric arc furnace the regulator contains a setting power mechanism, a unit of a dead band, an output of which is connected with the input of controlled reverse converter, to the output of which an electric engine of electrode travel is connected, and a threshold component, the output of which is connected to the control input of a controlled switch. The regulator is equipped with a magnifier, with a limit unit, an aperiodic filter, a summator and a unit for separation of error signal module, the output of which is connected to the input of the threshold component, while the input is connected with the output of the setting power mechanism, the first input of the summator and input of the magnifier, the output of which via the limit unit is connected with the input of the control switch, the output of which via the aperiodic filter is connected to the second input of the summator, the output of which is connected with the input of dead band unit.;EFFECT: upgraded efficiency of furnace and reduction of specific consumption of electric power.;3 dwg
