Abstract

PURPOSE:To make a wire difficult to be broken by shifting from the max. tensile stress during a die drawing and to improve mechanical properties by displacing the center of a segregation part from the wire rod center with a specified displacement rate. CONSTITUTION:As for the wire rod after hot rolled, the center of the segregation part is displaced from the wire rod center by >=20% displacement rate calculated from an equation 1. Wherein gamma: the radius of a true circle having the equal area to that of the wire rod or billet, gamma': length from the generated part of the segregation center to the displaced position of the segregation. Therefore, the wire rod with the displaced segregation center is shifted from the position of the max. tensile stress in the steel wire center part, the generations of the cracks during the wire drawing are reduced.
