The Influence on the Bar Straightness and Plastic Deformation the Roll Intersection Angle of a Two Roll Straightene

2roll 교정기의 교차각이 봉의 직진도와 소성변형에 미치는 영향

Two roll straightener showed the remarkable improvement in straightness betterment of the bar compared with other types of straightener. So, in this study we designed a two-cross straightener curvature for the straightness improvement of a bar and contact sections with respect to the variation of the gap between two-cross roll using nonlinear contact analysis. The Displacement in terms of a intersection angle between roll and bar was predicted on with the effect of a straightness and plastic deformation behaviors of the bar according to the roll drive of a two cross-roll straightener.
