Изобретение относится к металлургии, в частности к способам закрытия и открытия леток для выпуска металла из металлургических печей, например из вагранок, плавильно-восстановительных печей, доменных печей. Цель: повышение надежности операций открытия и закрытия летки и их оперативности. Закрытие летки, огнеупорные стенки которой охвачены водоохлаждаемым индуктором по большей части длины летки, примыкающей к наружной поверхности печи, осуществляют при обесточенном индукторе путем введения в ленточный канал металлического стержня. Для поддержания металла в расплавленном состоянии в части летки, примыкающей к рабочему пространству печи, в период между выпусками на часть индуктора в этой части летки подают напряжение. Для открытия летки включают индуктор по всей его длине и подают в него необходимую мощность.The invention relates to metallurgy, in particular to methods for closing and opening doors to release metal from metallurgical furnaces, for example from cupola furnaces, smelting reduction furnaces, blast furnaces. Purpose: improving the reliability of opening and closing operations of the tap hole and their efficiency. Closing the grooves, the refractory walls of which are covered by a water-cooled inductor for the most part, the length of the groove adjacent to the outer surface of the furnace, is carried out with a de-energized inductor by introducing a metal rod into the tape channel. To maintain the metal in the molten state in the part of the notch adjacent to the working space of the furnace, a voltage is applied to the part of the inductor in this part of the notch in the period between releases. To open, the tap holes include an inductor along its entire length and supply the necessary power to it.
