Title: Improvements in and relating to metallurgical slag reactions
IPC: H05B6/34
Filed: 1933-12-04
Abstract: Metallurgical slag reactions are conducted in an induction furnace constructed according to the parent Specification the induction coils having substantially horizontally disposed axes. The slag forms an emulsion in the molten metal due to the turbulent action.  Steel may be produced directly from iron ore or iron oxide in a single operation by feeding ore and carbon into a bath of molten steel or molten pig.  The process is of particular advantage for producing steel from slick or fine ores.  Reduction of carbon, phosphorous, or sulphur content is greatly accelerated. Specification 382,082, [Group XI], is referred to.

The pBr is maintained above 0À15, preferably between 1À0 and 1À3 during the crystal growth. The required conditions during crystal growth may be controlled by controlling (a) rate of addition of solutions, (b) temperature, (c) concentration of silver halide solvent, or (d) pAg.
