METHOD FOR PRODUCTION OF INGOTS FROM CHIPS Russian patent published in 1994 - IPC

Abstract RU 2013457 C1

FIELD: production of ingots from chips. SUBSTANCE: electroslag refining is effected in mold of consumable electrode formed of ships. Electrode is trapezoidal in cross-section with parallel sides ratio of at least 1: 5. Use of this electrode provides for electromagnetic mixing in process of melting due to magnetohydrodynamic convection to facilitate maximum gas evolution and recrystallization of seam metal. Cast ingots become more plastic and with high operate reliability. EFFECT: higher efficiency. 1 tbl
