Abstract

PURPOSE: To enable precise marking by abutting a marked piece precisely against the surface, by a method wherein a posture of the marked piece is made to change by adapting itself to a slope of an ingot. CONSTITUTION: When a cylinder rod 6 of a cylinder is extended, an up-and-down motion plate 7, a support 8, a marking set up plate 9, a marked piece fitted into a marking fitting hole 10 are lowered together and a marked part 14 of the bottom of the marked piece abuts against the surface 1a of an ingot 1. Since the marked piece is simply fitted into a marked fitting hole 10 of the marking set up plate 9 by empty weight, when the cylinder rod 6 is extended downward, it is floated and adapted itself to a slope. A rod 15 for pressing the marking against the surface la presses semispherical protrusion 13 and the surface 1a is marked. In this case, since the rod 15 for pressing the marking against the surface 1a presses semispherical protrusion 13, press force is transmitted completely irrespective of a posture of the marked piece and beautiful marking can be performed.
