Embodiment Construction
[0071] figure 1 The ladle has a circular horizontally extending bottom 10 with an upper horizontal surface 10o and a lower horizontal surface 10u. A generally cylindrical ladle wall 12 extends upwardly from the outer periphery 10 p of the ladle bottom 10 . The open upper end of the ladle is indicated by numeral 14 .
[0072] A stream of metal MS, shown by arrow M, enters the ladle through its open end 14 , flowing vertically downwards before hitting an impact zone 10i on the upper surface 10u of the ladle bottom 10 .
[0073] At least a part of the metal flow continues its flow (arrow F) towards a runner 16 arranged offset from said impingement zone 10i, which runner 16 extends from the upper surface 10u to the lower surface 10o.
[0074] Such as figure 1 As shown in , the runner 16 is filled with so-called filling sand FS, and a sand cone SC can be seen above the runner 16 . Filling material prevents molten metal from approaching the sprue during filling of the ladle. It...
