METHOD OF FLOW-TYPE METAL VACUUMIZING UPON CONTINUOUS CASTING Russian patent published in 1996 - IPC

Abstract RU 2060858 C1

FIELD: metal continuous casting process. SUBSTANCE: method comprises steps of feeding metal from a casting ladle to a vacuum chamber, provided by a vacuum guide; creating in the chamber a necessary residual pressure; treating the metal in the vacuum chamber; feeding it to an intermediate ladle through a branch pipe up to a predetermined level and then - into molds, from which ingots are being drawn. At casting process inert gas is being periodically fed into the branch pipe, and a level of a metal layer on a bottom of the vacuum chamber is being periodically raised and descended. EFFECT: enhanced efficiency of the method. 1 cl
