Abstract
Изобретение относитс к литейному производству, а именно к устройствам дл ввода измельченных порошковых материалов , например модификаторов, микрохолодильников , в расплав в стадии заполнени литейных форм, изложниц, кристаллизаторов при непрерывном и полунепрерывном литье. Целью изобретени вл етс повышение надежности в работе за счет исключени заполнени запирающего стопора, расположенного подвижно внутри неподвижной трубы, расплавом в период выпуска и его замораживани там в результате захо- лаживани порошковым модификатором, поступающим из дотирующей воронки. Дл этого неподвижна труба 2, закрепленна в стопорном ковше 1, в нижней части выполнена с отверсти ми, равномерно расположенными по окружности и тангенциально направленными к ее внутренней поверхности . Нижн кромка отверстий находитс на 10-15 мм выше дна ковша, отношение площади отверстий на неподвижной трубе к выходному отверстию ковша меньше или равно 1,3, а подвижный стопор 4 расположен внутри трубы. Дозирующа воронка 6 установлена выход щим носиком пр мо в центре по оси стопора. Поставленна цель достигаетс тангенциально расположенными отверсти ми в стенке неподвижной трубы , внутри которой находитс полый стопор, суммарна их площадь меньше или равна 1,3 площади выпускного отверсти ковша 2 ил у ЈThe invention relates to a foundry, in particular, to devices for introducing crushed powder materials, such as modifiers, microcoolers, into the melt in the stage of filling casting molds, molds, molds in continuous and semi-continuous casting. The aim of the invention is to increase reliability in operation by eliminating filling the locking stopper, which is movably located inside the fixed pipe, with the melt during the period of release and freezing it there as a result of cooling with powder modifier coming from the donating funnel. For this purpose, the fixed pipe 2, fixed in the stop bucket 1, is made in the lower part with openings evenly spaced around the circumference and directed tangentially to its inner surface. The lower edge of the holes is 10-15 mm above the bottom of the bucket, the ratio of the area of the holes on the fixed pipe to the exit hole of the bucket is less than or equal to 1.3, and the movable stopper 4 is located inside the pipe. The dosing funnel 6 is mounted with an outlet spout directly in the center of the axis of the stopper. The goal is achieved by tangentially located holes in the wall of the fixed pipe, inside which there is a hollow stopper, their total area is less than or equal to 1.3 of the area of the bucket outlet 2 or less.
