摘　　要：分析了滚筒式热板坯切头飞剪机的"自然位移"参数(Δz、hj);确定出不定积分常数Cj,平移自然位移剪刃侧间隙曲线族,得出了剪切工艺过程剪刃侧间隙恒定的结论。进而阐明了上下剪刃位移间隙的连续可调性,可调双向性。并确定了热板坯的断裂"区"、"点"及其有关问题等。This paper analyzed the natural displacement parameter Δz、hj, determined indefinite integral con-stant cj and curves of panning natural displacement gap part, and obtained a conclusion that natural displace-ment gap constant invariableness. Additionally, displacement gap could continuous adjusted and a two-way ad-justment is feasible. While crack area and point and other relative issue were determined.
