A laboratory study of reactions in the hot spot area and in droplets during top lance blowing
2004 (English)Conference paper (Refereed)
The reactions in the hot spot area and in droplets during top lance blowing in a laboratory induction furnace were investigated. The experiments were performed in alumina crucible, with an inner diameter of 150mm and a height of 300mm. In hot spot sampling, the lance was lowered with a flow of inert gas through it to detect where the hot spot was going to be situated. In metal droplet sampling, the droplets were captured with an alumina cup that had a quartz tube as grip. A difference in size, appearance and shape were noted between droplets from melts with and without silicon addition.
