Abstract

PURPOSE: To pressure-weld the surface of an ingot, prevent surface cracking and improve yield by enclosing and screwing-down the ingot at a surface temp. and draft higher than specified right under a continuous casting mold.
CONSTITUTION: An ingot 2 is enclosed and screwed down from the surroundings by rolls 3a, 3b, 4a, 4b, right under a continuous casting mold 1. At this time, the ingot 2 is screwed down from the surroundings until the draft by the formula I reaches ≥2.0% in the state that the surface temp. of the ingot 2 is above 1,100°C, whereby the surface of the ingot is pressure-welded.
