Изобретение относитс к электротермии , в частности к управлению электрическим режимом дуговой электропечи .The invention relates to electrothermal, in particular, to the control of the electric mode of an electric arc furnace.
- Известно устройство дл управлени электрическим режимом дуговой электропечи, содержащее блок определени стадии плавлени шихты, в котором дл определени момента формировани жидкого металла в ванне используетс сигнал напр жени двигателей перемещени электродов tlj.- A device for controlling the electric mode of an electric arc furnace is known, which contains a block for determining the melting stage of the charge, in which the voltage signal of the displacement motors of the electrodes tlj is used to determine the moment of formation of the molten metal in the bath.
Недостатком такого устройства вл етс низка точность определени момента по влени жидкого металла, обусловленна обвгипами шихты, а также низкое быстродействие из-за необходимости введени выдержки времени нд формирование сигнала.The disadvantage of such a device is the low accuracy of determining the moment of occurrence of a liquid metal, due to the charge of the charge, as well as low speed due to the necessity of introducing a time delay for signal formation.
Наиболее близким по технической сущности к предлагаемому вл етс устройство дл управлени электрическим режимом дуговой электропечи, содержащее блок измерени электрических параметров, программный блок, один из выходов которого соединен с переключателей ступеней напр жени печного трансформатора, а второй с регул тором мощности, подключенным ,к исполнительному механизму перемещени электродов каждой фазы, -и блок определени стадии плавлени шихты с 2}.The closest in technical essence to the present invention is a device for controlling the electric mode of an electric arc furnace, which contains a unit for measuring electrical parameters, a software unit, one of the outputs of which is connected to the switches of the voltage steps of a furnace transformer, and the second with a power regulator the mechanism for moving the electrodes of each phase, and the block determining the stage of melting of the charge with 2}.
Недостатком указанного устройства вл етс сложность построени блока определени стадии плавлени шихты.The disadvantage of this device is the difficulty of building a block for determining the stage of melting of the charge.
Цель изобретени - упрощение устройства.The purpose of the invention is to simplify the device.
Поставленна цель достиг аетс The goal has been achieved
10 тем, что в устройстве дл управлени электрическим режимом дуговой электропечи.блок определени стадии плавлени шихты снабжен элементом выделени посто нной составл ющей 10 in that, in the device for controlling the electric mode of the electric arc furnace, the unit for determining the stage of melting of the charge is equipped with a constant-selection element
15 напр жени дуги и пороговым элементом , св занным выходом со входом программного блока, а входом с выходом элемента выделени посто нной составл ющей напр жени дуги, 15 the arc voltage and the threshold element connected with the output to the input of the program block, and the input with the output of the selection element of the constant component arc voltage,
20 подключенного входом к выходу- блока измерени электрических параметрбв. 20 connected by the input to the output of the electrical parameter measurement unit.
На чертеже приведена функциональна схема устройства.The drawing shows a functional diagram of the device.
