    • The thin wall iron tube, of wall thickness below 5mm., and thickness/ diameter ratio less than 10%, is continuously cast through a vertical die. The head of the die is fitted into the casting orifice in the base of the ladle with a heated core suspended in it to form an annular mould. The die, below the shell of the ladle, is a thickwalled graphite tube, surrounded by a cooling jacket. The head is a composite, comprising a truncated conical lip, one third the thickness of the main tube, and surrounded by a thermally and melt iron insulating ceramic ring, level with the exposed top edge, and filling the space between the core and the die wall.
    • 薄壁铁管的壁厚小于5mm,厚度/直径比小于10%,通过垂直模具连续铸造。 模头的头部装配在钢包的底部中的铸造孔中,其中悬挂在其中的加热芯形成环形模具。 在钢包的外壳下方的模具是厚壁石墨管,被冷却套包围。 头部是复合材料,其包括截头圆锥形唇缘,三分之一的主管的厚度,并且被热和熔化的铁绝缘陶瓷环包围,与暴露的顶部边缘水平,并且填充芯部和模具之间的空间 壁。
