Claims (2)

1. Способ контроля вакуумной дуговой плавки путем измерения действующего значения технологического параметра и сравнения его с пороговым значением, отличающийся тем, что в процессе плавки регистрируют изображение участка ванны жидкого металла, измеряют скорость изменения площади этого изображения и при отклонении измеряемой скорости от порогового значения фиксируют возникновение аварийной ситуации, причем регистрацию изображения участка ванны проводят в области спектра, свободной от излучения плазмы дуги, например, в инфракрасной области.1. A method of controlling a vacuum arc melting by measuring the effective value of a process parameter and comparing it with a threshold value, characterized in that during the melting process, an image of a portion of a bath of molten metal is recorded, the rate of change of the area of this image is measured, and when the measured speed deviates from the threshold value, the occurrence an emergency situation, and registration of the image of the bath section is carried out in the spectral region free of radiation from the arc plasma, for example, in infrared blasts. 2. Способ по п.1, отличающийся тем, что при измерении скорости изменения площади изображения используют изображение одной четвертой части площади ванны жидкого металла.2. The method according to claim 1, characterized in that when measuring the rate of change of the image area using an image of one fourth of the area of the bath of liquid metal.
