【摘要】 为了提高冷轧压力模型的精度,进行了外区影响的实验研究,结果表明,当ε较小时外区有较大影响,当ε>10～15％时,影响实际上已不显著,随原始厚度增加,其影响也就愈大,计算轧制压力时在一定情况下应考虑外区的影响,实验结果完全与塑性力学的观点一致。更多还原

【Abstract】 In order to increase the precision of the roll-force models for cold strip-rolling, outer zoneseffect is studied. The results of the tests show that the outer zones have greater influence when εis smaller and this effect is not obvious when ε>10-15%. The influence increases with increasinginitial thickness. Therefore this factor must be considered when calculating roll force under certainconditions. The results of the test are in complete agreement with plastic mechanics.更多还原
