Abstract

Верхняя погружная фурма имеет внешнюю оболочку из трех, по существу, концентрических труб фурмы, по меньшей мере одну дополнительную трубу фурмы, расположенную концентрически внутри оболочки, и кольцеобразную торцевую стенку на выпускном конце фурмы, которая соединяет концы самой внешней и самой внутренней труб оболочки фурмы на выпускном конце фурмы и отстоит от выпускного конца промежуточной трубы оболочки фурмы. Охлаждающая текучая среда может циркулировать внутри оболочки, протекая к выпускному концу и от него. Зазор между торцевой стенкой и выпускным концом промежуточной трубы обеспечивает сужение потока охлаждающей текучей среды для увеличения скорости течения охлаждающей текучей среды в этом зазоре. Дополнительная труба фурмы определяет центральный канал и отстоит от самой внутренней трубы оболочки фурмы, определяя кольцеобразный проход, в результате чего материалы, проходящие по каналу и по проходу, смешиваются вблизи выпускного конца фурмы. Торцевая стенка и прилегающая к ней малая часть длины оболочки включают сменную сборку наконечника фурмы.
