Impact rotating wheel electroslag cast-weld manufacturing method

An electroslag cast-weld manufacturing method for an impact rotating wheel specifically comprises the steps that the impact rotating wheel is divided into a spoke unit and a bucket unit along the circumference, a wedge-shaped cast-weld groove is reserved in the circumference of the spoke unit, and a trapezoidal connecting plate is reserved in the bucket root direction of the bucket unit; a combined crystallizer and a consumable electrode are manufactured according to the structural characteristics and the boundary dimensions of the split spoke unit and the split bucket unit; the method comprises the following steps: firstly, carrying out block electroslag cast-welding on spoke units, and then adjusting the spoke units to rotate vertically and circumferentially; a bucket unit combined crystallizer and a consumable electrode are clamped on a cast-weld groove, cast-weld of a first bucket unit is carried out, after cast-weld of the first bucket unit is finished, a spoke is rotated to carry out cast-weld of a seco
