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...

Abstract

The invention relates to a ladle bottom being part of a metallurgical ladle for treating a metal melt as well as a corresponding metallurgical ladle.

Description

technical field [0001] The invention relates to ladle bottoms as part of metallurgical ladles for processing metal melts, and to corresponding metallurgical ladles. Background technique [0002] Such a ladle bottom is made of a refractory ceramic body providing an upper surface, a lower surface and a runner extending between the upper and lower surfaces. As part of the ladle, the ladle bottom fits within one end of a corresponding wall portion, wherein the wall extends from the periphery of the ladle bottom. [0003] The ladle and ladle bottom are described hereinafter as being horizontally arranged at the ladle bottom and at the location at the lower end of the ladle, respectively. [0004] The metal melt is poured (cast) into the ladle via the open upper end of the ladle. The metal stream first impinges on the ladle bottom before being redirected to flow along the upper surface of the ladle bottom and towards the sprue which is closed by filler sand at this stage of the ...
