METHOD OF FLOW-TYPE METAL VACUUMIZING AT CONTINUOUS CASTING Russian patent published in 1995 - IPC

Abstract RU 2037365 C1

FIELD: metallurgy. SUBSTANCE: method comprises steps of feeding an inert gas at process of flow-type vacuumizing simultaneously through a bottom of a vacuum chamber and through a casting hole of the casting ladle into vacuum chamber; setting a flowrate of the gas through the bottom of the vacuum chamber in a range 0.5-1.5 of its flowrate through the casting hole of the casting ladle. EFFECT: enhanced manufacturing process. 1 cl, 1 dwg, 1 tbl
