METHOD FOR MAKING LAMINATE INGOTS BY ELECTROSLAG REFINING Russian patent published in 2001 - IPC

Abstract RU 2163269 C1

FIELD: foundry, namely electroslag refining. SUBSTANCE: method comprises steps of introducing alloying elements into melting chamber at cutting off electric current in time periods equal to Δτ=0.2m/v, where m - mass of liquid metallic bath during stationary period of melting, kg; v - fusion velocity of casting, kg/c. EFFECT: strict layer-by-layer separation of alloying elements in casting at their batch feeding to melting chamber. 2 dwg, 2 tbl
