METHOD OF REFINING METAL Russian patent published in 2006 - IPC C22B9/10 C21C7/76 

FIELD: metallurgy; foundry for manufacture of castings.

SUBSTANCE: proposed method consists in subjecting the salt whose specific gravity is lesser than that of metal by 1.5-10.5 times to vibration at pouring molten metal into it. The lesser is the difference between specific gravity of salt and metal, the higher is intensity of vibration of molten salt. Proposed method facilitates the refining process, reduces power requirements by 1.5-2.6 times and amount of non-metallic inclusions by 2-3 times and increases tensile strength of cleaned metal by 1.2-1.5 times.

EFFECT: enhanced efficiency; reduced power requirements.
