In the drawing, a structural diagram explaining the descriptive method of the manager. The power of the viuhri of the specified technological range is supported by the power regulators 1 by moving the electrodes 2, and the boot-up speed is supported by the regulator 3 of the load speeds by acting 1 on the actuator; the 1st load mechanism (for example, changing the speed Bleed auger 4). The transition from one technological terminal to another is carried out automatically with the aid of the setting device 5. The ino feed rate is corrected to the temperature (the metal inside each technological interval is carried out with the help of the metal temperature controller 6 and the change in the job setting to the download speed controller. Mo; me; The beginning of the loading of sponge iron from the bunker 7 into the furnace 5 is characterized by the presence of liquid nonall in the hearth of the furnace. As a parameter used to determine the presence of a liquid metal in the furnace: The power factor is increased, an increase of 1 of which three operating the liquid bath furnace is associated with an improvement of vcc 0.3 and; mount; and arcs. The sponge iron is loaded into the furnace when the specified power factor 1 value is reached, measured by the unit 9 of determining the start of loading, according to the signal of which, the driver of the automatic unit sets the task to the POWER POWER controller, to the download speed controller and to the temperature controller, and a continuous, or discrete, temperature measurement starts simultaneously with this time. If the temperature of the metal bath does not match the specified temperature controller 6, the sponge iron loading speed is corrected by changing the task to the controller 3 so that the temperature rises or the speed of the metal changes from the specified value, while loading decreases - reduce. The invention The method of controlling the process of melting sponge iron in an electric furnace, including a change in the acorosity of the sponge iron in the furnace depending on the electrical power taken from the network, in order to increase the temperature of the metal and reduce the duration of the melt Sponge iron 3arpy3iKy Begin, with the fulfillment of the following ratio by electrical parameters: p - p 3 a p where RH is the active power taken from the network; Pp - rea, power, power taken from the network, power within 1 each technological interval is kept real at the maximum allowable level ъ a correction is introduced. Sponge iron loading speed is proportional to the deviation of the metal temperature from the set value so that of the specified value, the load rate is increased, and in the opposite direction, it is reduced.
