Abstract

PURPOSE: To contrive the stabilization of quality and the labor saving, by correcting the twist residual or newly generated after the correction work for the twist generated in the initial forging work, through choosing the optimum corrective quantity using the quantity of that residual twist, the corrective quantity for the rotation of the tongue, etc.
CONSTITUTION: The rotatioanl position detector 10 delivers a position signal depending on the memory stored in the manipulator for the correct position of the ingot, and on the rotational displacement of the tongue 3 due to the twist; the twist is detected according to this position signal together with the memory stored in the manipulator controller 18. Hereby, at first, the force always returning to the normal position is acted; next, the forging work is recorded in the oscillograph, etc., and when a twist generates, the position of the tongue 3 is corrected on purpose to correct the twist; and for the third way, the twist is corrected using the data relating to the twist generated formerly, the corrective quantity of rotation of the tongue for correcting this twist, the corrective quantity of thus corrected twist, etc.
