ABSTRACT:
For producing metallic bar stock there is first of all fabricated a primary product of substantially regularly round or angular cross-section, and this primary product is then deformed in cross-section to the final dimension corresponding to the bar stock by means of shaping. To provide for an efficient production of high-quality bar stock also in a minor quantity, the completely solidified primary product is subjected to a forging operation for a structural improvement before shaping it to the final dimension, during which forging off in one processing plane a spreading-restricted reduction of the cross-section in the range from (1.5 to 5):1 is effected.
