Abstract

Погружной стакан или труба, применяющаяся для непрерывной разливки расплавленного металла, в особенности раскисленной алюминием стали. Погружной стакан формуют из смеси долома и графита, которые связаны вместе в карбонизированной матрице. Погружные стаканы или трубы, согласно изобретению, имеют улучшенное сопротивление термическому удару. Кроме того, погружные стаканы или трубы согласно изобретению сопротивляются образованию в них окиси алюминия, когда они используются для непрерывной разливки расплавленной раскисленной алюминием стали. Следовательно, эти трубы или погружные стаканы могут быть использованы в процессе непрерывной разливки стали в течение длительного периода времени без необходимости периодически останавливать процесс и заменять трубы, по мере того как они забиваются окисью алюминия. В результате устойчивости к термическому удару обычная стадия предварительного нагрева перед контактом погружного стакана расплавленным металлом сильно сокращается.Международная заявка была опубликована вместе с отчетом о международном поиске.
