Claims (2)

1. Способ контроля вакуумной дуговой плавки, включающий измерение значения технологического параметра, сравнение его с расчетным параметром и фиксирование аварийной ситуации, отличающийся тем, что технологическим параметром берут площадь видимого изображения ванны жидкого металла, которая фиксируется оптическим датчиком с оптической осью, проходящей параллельно оси печи и расположенной между внутренней поверхностью изложницы и наружной поверхностью расходуемого электрода, а расчетным параметром назначают видимую площадь ванны жидкого металла, выраженной как однозначная функция от аргументов смещения осей электрода относительно осей печи в двух взаимно перпендикулярных направлениях и длины расходуемого электрода, при этом фиксирование аварийной ситуации производят при значениях аргументов смещения осей электрода больше пороговых, а длины электрода меньше порогового.1. A method of monitoring a vacuum arc melting, including measuring the value of a technological parameter, comparing it with a calculated parameter and fixing an emergency, characterized in that the technological parameter takes the area of the visible image of the liquid metal bath, which is fixed by an optical sensor with an optical axis parallel to the axis of the furnace and located between the inner surface of the mold and the outer surface of the consumable electrode, and the visible area of the liquid bath is assigned by the calculation parameter metal, expressed as a single-valued function of the arguments of the displacement of the axis of the electrode relative to the axis of the furnace in two mutually perpendicular directions and the length of the consumable electrode, while fixing the emergency situation when the values of the arguments of the displacement of the axes of the electrode are greater than the threshold, and the length of the electrode is less than the threshold. 2. Способ по п.1, отличающийся тем, что контроль вакуумной дуговой плавки производят двумя или более оптическими датчиками, которые независимо друг от друга фиксируют видимое изображение ванны.2. The method according to claim 1, characterized in that the control of vacuum arc melting is carried out by two or more optical sensors, which independently of each other capture a visible image of the bath.
