“…refining and solidification processes [1][2][3][4] . Traditional ESC methods, including electroslag one-step casting (ESOSC), electroslag step-by-step casting (ESBSC), electroslag pouring (ESP) and centrifugal electroslag casting (CESC), have been applied in producing specialshaped castings, such as rotary bodies, crankshafts, and turbine blades [5][6][7][8][9][10][11][12][13][14] . In ESOSC, to obtain a qualified part, the mold cavity needs to be enlarged to increase the casting allowances.…”

Electroslag casting with parallel fixed-movable dual electrodes is a new method for achieving better quality of castings in complex mold cavities. In this work, a mathematical model, y=kx 2 +(k+1)x, was established to describe the ideal correlation between the current ratio (y) and the cross-sectional area ratio (x) of the dual electrodes, where k is the filling ratio. Investigation was conducted on the electroslag casting process with dual electrodes of various cross-sectional areas, but at a constant k value. The experimental results indicated that the ideal correlation was obtained at the stable casting stage, and the fitting results were consistent with the experimental results at certain k values. The experimental findings show that better castings can be obtained when the current ratio is greater than 1.536 and the cross-sectional area ratio is greater than 0.5.
