Description

Известные способы замера температуры движущейс  струи мета.чла путем применени  оптических ардометров и фотопирометров не позвол ют получать истинное значение температуры жидкого металла вследствие наличи  окислов на его поверхность.The known methods for measuring the temperature of a moving jet of a metric by using optical ardometers and photopyrometers do not allow to obtain the true value of the temperature of the liquid metal due to the presence of oxides on its surface.

Особенность насто щего изобретени  заключаетс  в том. что, с пелью увеличени  точности контрол  температуры покрытой окислами поверхности металла, определ ют интегральное значение  ркостной температуры поверхности расплавленного металла при его интенсивном движении вдоль визируемой поверхности. Посто нна  времени электрической интегрирующей цепочки определ етс  частотой флуктуации  ркостной температуры визируемой поверхности металла.A feature of the present invention is. that, with the aim of increasing the accuracy of controlling the temperature of the metal surface covered with oxides, the integral value of the surface temperature of the molten metal is determined during its intensive movement along the surface of the metal. The time constant of an electrical integrating chain is determined by the frequency of fluctuation of the viscosity temperature of the metal surface to be sighted.

При описываемом способе контрол  температуры с помощью быстродействующего фотопирометра ФП-3 определ етс  значение  ркостной температуры поверхности металла, покрытой окислами. Стабильность результатов измерений достигаетс  при условии интенсивного движени  металла вдоль визируемой поверхности. Требуемое дл  данного способа контрол  температуры металла быстрое действие прибора обеспечиваетс  за счет введени  в схему после фотопирометра ФП-3 подобранной линейной интегрирующей цепочки, PC, посто нна  времени которой определ етс  частотой флуктуации  ркостной температуры визируемой поверхности металла.In the described method of temperature control using the high-speed photopyrometer FP-3, the value of the surface temperature of the metal coated with oxides is determined. The stability of the measurement results is achieved under the condition of intense metal movement along the sighted surface. The rapid operation of the device required for this method of controlling the metal temperature is achieved by introducing a selected linear integrating chain, PC, after the photopyrometer FP-3, PC, the time constant of which is determined by the frequency of fluctuations in the viscosity temperature of the metal surface.

Измерение интегрального значени   ркостной температуры значительно повыщает точность измерений температуры расплавленного металла и исключает возможность больщих ощибок. Предлагаемый способ контрол  можно примен ть при плавке металлов независимо от ее объема при условии создани  интенсивного движени  металла при по№ 141663- 2 мощи , например, ультразвукового пол  и создани  магнитного дуть . Применение этого способа способствует автоматизации и механизации дозирующих устройств при производстве стальных отливок методами машинного лить .Measuring the integral value of the brightness temperature significantly increases the accuracy of measuring the temperature of the molten metal and eliminates the possibility of large errors. The proposed control method can be used in the smelting of metals, regardless of its volume, provided that intense metal movement is created at item 141663-2, such as an ultrasonic field and a magnetic blow. The application of this method contributes to the automation and mechanization of dosing devices in the production of steel castings using machine casting methods.
