METHOD OF LIQUID STEEL PROCESSING IN VACUUM CHAMBER Russian patent published in 2009 - IPC C21C7/10

Abstract RU 2348700 C1

FIELD: metallurgy.

SUBSTANCE: invention concerns ferrous metallurgy and can be used at cycling and circulating degassing of steel during the process of out of furnace processing. In this method vacuum chamber is warmed before degassing, it is implemented cycling and circulating degassing, steel is heated and alloying materials are introduced. Steel heating is implemented by one or several lasers during the process of degassing and after alloying materials introduction.

EFFECT: mix expansion and reduction of cost price of processed steels.
