Title: Procede d'evacuation a haute efficace des scories du fer en fusion et appareil de mise en oeuvre dudit procede
Inventor: SHENG FUCHUN
IPC: C21C5/46
Filed: 2004-04-05
Granted: 2013-03-19
Abstract: L'invention concerne un procédé permettant d'évacuer de façon efficace des scories du fer en fusion ainsi qu'un appareil destiné à cet effet. Deux herses fixées à l'extrémité avant d'un cantilever tournent au niveau du fer en fusion. Les scories solides sont saisies lorsque les deux herses se rapprochent l'une de l'autre; les deux herses se retirent ensuite vers le rebord de la poche de coulée, ce qui permet d'évacuer les scories de ladite poche de coulée. L'évacuation des scories est achevée en trois minutes, la rentabilité de l'évacuation des scories étant d'au moins 90 %. La quantité de fer évacuée en même temps que les scories est considérablement réduite et la perte de fer est rigoureusement régulée dans une proportion de 0,1 %.
