METHOD FOR TREATMENT OF MOLTEN METAL Russian patent published in 1996 - IPC

FIELD: metallurgy. SUBSTANCE: prior to treatment metal is overheated by 80-120 ^o C above liquidus temperature. Time of action of electric and water hammer is found from relation τ = 10^-3(8,4+0,02 Δt) M^0,5•B_S(m)•Δt, where τ is duration of action, min; Dt is temperature of overheating of melt above liquidus temperature, ^o; B_S(m) is action intensity, J/kgf; M is mass of melt. EFFECT: enhanced efficiency. 2 tbl
