Basic analysis of dieless drawing

$15.00

Dieless drawing involves continuous pulling of a tensilely stressed rod through a source of heat so as to allow local stretching of the heated, softened metal. The dieless technique has potential for low carbon steel drawing. Past efforts with this technique have often encountered cross section variation and frequent breakouts. Modern process control systems motivate new evaluations, however, and this paper presents a mathematical model.
