ABSTRACT:
A procedure is disclosed for treating a metal melt, such as an iron melt, with a vaporizable substance, such as, for example, unalloyed magnesium. The treatment is carried out in a reaction vessel within whose reaction space a wall enclosed chamber is located which communicates with the reaction space of the vessel through vertically spaced passages. The substance to be vaporized is placed into the chamber and metal melt is charged into the reaction space of the vessel. The metal melt rises along the wall of the chamber and enters the chamber to vaporize the substance. The passages which establish the communication between the chamber and the reaction space may be initially blocked by mechanical means or by a material which is dissolved or destroyed by the metal melt.
