METHOD OF ALLOYING OF STEELS AND ALLOYS DURING PROCESS OF ELECTROSLAG REMELTING Russian patent published in 2009 - IPC C22B9/18 

Abstract RU 2355790 C2

FIELD: metallurgy.

SUBSTANCE: invention relates to special electrometallurgy and can be used during the receiving of high-quality alloyed steel and alloy during the electroslag remelting. Method includes feeding of portion of alloying materials into furnace mold with flux before the start of remelting and the rest portion during the remelting process, herewith feeding of alloying materials before the beginning of remelting in amount 1-2% of flux weight is implemented in the mixture with flux. Alloying materials are crushed up to fraction 2-3 mm.

EFFECT: uniform distribution of alloying elements by ingot and reduction of discard of bottom part of ingot.
