FIELD: plastic metal working, namely production of forged pieces of ingots in forging complexes. ^ SUBSTANCE: method comprises steps of billeting ingot and forging it in several passes. Billeting is performed in four-striker forging apparatus for billeting ingots. At each unit reduction ingot is reduced in vertical plane at higher deformation degree than in horizontal plane. Forging complex includes forging press with movable tool table having several positions for changing forging tools. Tool has at least two four-striker forging device. Each device has four strikers secured to holders of upper, lower and lateral strikers. In first position of table four-striker forging device for billeting ingots is arranged. Angle between inclined surfaces in each holder of lateral striker of said device is in range 95 - 160°. Working surfaces of upper and lower strikers are longer than working surfaces of lateral strikers. When all strikers are in closed position, rectangle is formed in their cross section. ^ EFFECT: possibility for forging ingots with large cross section at improved efficiency. ^ 6 cl, 7 dwg, 2 tbl, 1 ex |
