Title: Improved ferrous alloys
IPC: C22C37/00
Filed: 1957-11-18
Abstract: A cast iron containing Al 1.0-5.0%, Mn 1.5-15.0% and Ni 0 to less than 2.0% has a structure in the "as-cast" condition comprising free graphite in a matrix of austenite and/or an acicular transformation constituent thereof, e.g. a matrix of austenite and bainite.  The relative contents of Al and Mn may be adjusted to produce either a white or a gray cast iron.  Any of the common alloying elements used in cast irons may be included, e.g. Cr, V, Mo, Cu, Ni, Co.  Other elements such as Ca, Cl, Mg, Li, Na, K, Bi, Ti may also be present, e.g. Mg may be added to render the graphite carbon in spheroidal form.  The cast iron may be heat treated.  Thus an "as-cast" bainite structure may be converted to austenite by quenching from 1600-1900 DEG F. or even lower depending on the composition.  An austenitic product may be precipitation hardened at 900-1200 DEG F.  The alloy may be produced by introducing Al as a ladle addition, in the form of ingot or shot or as an alloy, e.g. with manganese, to high manganese metal melted in an electric furnace or acid lined cupola. Alternatively Al may be added as chunks mixed with Al powder and a metallic oxide.  These constituents act as an exothermic mixture to assist alloying and to improve the fluidity of the melt. Specification 281,051 is referred to.

Title: Process and apparatus for making anhydrous alumina
IPC: C01F7/445
Filed: 1960-10-27
Abstract: A continuous process of making inert, stable, anhydrous alumina, principally of alpha alumina, from hydrated alumina, comprises feeding the hydrated alumina to a first and endothermic stage, supplying to the alumina in the first stage sufficient heat to effect a rapid preliminary substantially complete dehydration of the alumina without allowing any substantial change in the physical structure of the dehydrated alumina, continuously passing the dehydrated alumina from the first stage to a second and exothermic stage, maintaining the dehydrated alumina in the second and exothermic stage at a higher temperature and for a longer period of time than in the first stage to ensure complete dehydration of the alumina and to effect substantially complete recrystallization of the dehydrated alumina, and collecting the dehydrated recrystallized alumina at the end of the second stage, the vapour driven off the alumina being separately extracted from each stage.  The first stage may be carried out for up to 60 seconds at a temperature of 300 DEG -600 DEG C., and the second stage for 10 to 120 minutes at 900 DEG -1200 DEG C. The heating for the first stage may be accomplished by flowing hot gases counter-current to the alumina hydrate.  In the described apparatus, the first stage is carried out in a series of cyclone heat exchangers, and the second stage in either a fluidized bed or a rotary furnace. Since the second stage is exothermic it is sufficient to initially heat the second stage apparatus to the required temperature, no further heating then being necessary.
