拉弯矫直过程的张力损耗问题在拉矫应用理论中研究较少，本文从力学角度深入分析了张力损耗问题，明确了张力损耗实际上反映了拉弯变形时拉应力和弯应力的相互影响关系 The problem of tension loss in tension straightening process is less studied in straightening application theory. In this paper, the tension loss problem is analyzed in detail from mechanics. It is clear that the tension loss actually reflects the interaction between tensile stress and bending stress relationship
