Title: Treatment of molten steel in ladle - where linear motors are used to transfer steel to overhead auxiliary vessel for vacuum degassing and/or alloying (AT 15.5.81)
Inventor: NARITA KIICHI
IPC: C21C7/10
Filed: 1980-04-18
Abstract: A vessel is located above the ladle, and is provided with one or more pipes which project downwards into the molten steel in the ladle. Each pipe is surrounded by a linear motor driven at a frequency of 50-60 Hz and used to lift part of the steel into the vessel while simultaneously heating the steel. The steel in the vessel is subjected to degassing by a vacuum, and/or alloying elements are added. The linear motors are then used to return the molten steel to the ladle after a prescribed time. The transfer of the molten steel to and from the vessel is repeated several times to produce a homogeneous melt. By using a frequency of 50-60 Hz to drive the linear motors, the latter heat the steel while transporting it between the ladle and the vessel. The heat aids both the dissolving of alloying elements and the vacuum degassing of the molten steel. The stirring action is also very efficient.

Title: Process for preparing a granular catalyst for the synthesis of ammonia
Inventor: LYTKIN VIKTOR PETROVIC
IPC: B01J23/745
Filed: 1981-01-29
Abstract: The present invention relates to the field of inorganic synthesis and in particular to a process for preparing a granular catalyst for the synthesis of ammonia. The process proposed according to the invention consists in melting and oxidising iron with the use of promoters to produce a melt of the catalyst composition, and in subsequent granulation. According to the invention, the melting and the oxidation of iron with the use of promoters are carried out simultaneously in a thin film of the melt of the catalyst composition being formed, while granulation of said melt is effected by an air stream which ensures the horizontal movement of the granules produced and their cool-down to 1000 DEG C; then the granules produced, as they cool down spontaneously, are reduced by means of a reduction gas. The process proposed is expected to find wide use in the nitrogen industry.
