接触開始位置（噛み込み開始位置）が異なつて
くるため、各パス相互の長手寸法にずれを生
じ、被加工材の長手寸法に不具合を生じる。 When the rolling reduction amount is adjusted, the contact start position (biting start position) between the roll die and the workpiece differs, which causes a deviation in the longitudinal dimension of each pass, causing a problem in the longitudinal dimension of the workpiece.

フオージングロール型の摩耗（熱間加工を行

る。）に伴う微調整が全体調整方式では困難で
ある。 It is difficult to make fine adjustments due to the wear of the forging roll type (the contact surface with the workpiece gradually wears out when hot working is performed) using the overall adjustment method.

同様なことが、フオージングロール設備の各
摩耗部（例えばロール軸軸受メタル）の劣化に
対する微調整に関してもいえる。 The same thing can be said about fine adjustments for deterioration of each worn part of the forging roll equipment (for example, the roll shaft bearing metal).

さらに、フオージングロールの型設計上の誤

By setting d 3 , d 4 , and d 5 , it is possible to obtain the optimum rolling reduction amount in each pass, and the roll biting start position l 2 ,
By configuring l 3 , l 4 , and l 5 to be variable, and setting these positions l 2 , l 3 , l 4 , and l 5 for each pass, the bite position of each pass can be optimized. Make it.
