Abstract

A method of continuously rolling a ferrous workpiece into a finished round, comprising rolling the workpiece in successive first and second roll passes at an elevated temperature of between about 650 to 1000° C., the first and second roll passes each being defined by two work rolls and being dimensioned to effect a combined reduction in the cross sectional area of the workpiece of at least about 20-55%, with an accompanying effective strain pattern dominated by a concentration of maximum effective strain at a central region of the cross sectional area; and while the effective strain pattern remains dominated by a concentration of maximum effective strain at a central region of the cross section, continuing to roll the workpiece in at least third and fourth consecutive roll passes, each of the third and fourth roll passes being defined by at least three rolls and being sized to effect a combined reduction in the cross sectional area of the workpiece of not more than about 4-25 %.
