Description
работы печи и она будет работать как печь периодического действи .furnace operation and it will work as a batch furnace.
Рассмотрим предлагаемый способ на примере плавки чугуна (см. чертеж) в индукционной печи I. По желобу 2 в печь подаетс шихта, котора плавитс и нагреваетс до температуры 1480-1510°С. При увеличении уровн расплава через порог слива он выливаетс . Регул тор уровн 3 поддерживает посто иным задаиный наклон печи путем управлени приводом (дозатором) подачи 4, а также изменением расхода расплава с помощью устройства 5, которое мен ет угол наклона печи а°. Регул тор 6 электрической мощности поддерживает максимальную мощность . Датчик 7 температуры контролирует температуру металла на выпуске, величина которой задана в сумматоре 8 в пределах 1450-1480°С. При отклонении температуры от заданного значени сигнал ошибки из сумматора 8 поступает в схему регул тора уровн 3, где пропорционально величине отклонени автоматически измен етс коэффициентConsider the proposed method using the example of cast iron smelting (see drawing) in an induction furnace I. Through chute 2, a mixture is fed into the furnace, which melts and heats to a temperature of 1480-1510 ° C. As the level of the melt rises over the drain threshold, it pours out. The level 3 regulator maintains a constant, setpoint inclination of the furnace by controlling the drive (metering unit) of supply 4, as well as by changing the melt flow rate using device 5, which changes the inclination angle of the furnace a °. The electric power controller 6 maintains maximum power. The temperature sensor 7 controls the temperature of the metal at the outlet, the value of which is set in the adder 8 within 1450-1480 ° C. When the temperature deviates from the setpoint, the error signal from the adder 8 enters the level 3 regulator circuit, where the coefficient automatically changes in proportion to the deviation value
передачи (усилени ) регул тора. Последний, воздейству на привод 4 и устройство 5, измен ет скорость подачи и слив металла до достижени заданной температуры. В результате дл заданной температуры металла на выпуске будет поддерживатьс максимальна допустима скорость подачи шихты и слива металла. Причем непрерывный процесс плавки будет осуществлен с максимальной производительностью при заданном тепловом режиме .transmission (gain) of the controller. The latter, acting on the actuator 4 and the device 5, changes the feed rate and metal discharge until the set temperature is reached. As a result, for a given metal temperature at the outlet, the maximum permissible feed rate of the charge and discharge of the metal will be maintained. Moreover, the continuous melting process will be carried out with a maximum performance at a given thermal mode.
Предмет изобретени Subject invention
Способ регулировани теплового режима непрерывно действующей индукционной печи путем регулировани уровн расплава, отличающийс тем, что, с целью достижени максимальной производительности печи при посто нном тепловом режиме, корректируют подачу шихты и слив металла пропорционально отклонению температуры металла на выпуске от заданной.The method of controlling the thermal regime of a continuously operating induction furnace by adjusting the level of the melt, characterized in that, in order to achieve maximum furnace performance under constant thermal conditions, the charge supply and discharge of the metal is proportional to the deviation of the temperature of the metal at the outlet from the set one.
