研究了各向异性钢板方坯拉伸的变形机理。通过大量试验,对比了圆坯、方坯的拉伸力,极限拉伸比,拉伸件有效高度及壁厚变化规律。在较大拉伸比的情况下,方坯与圆坯相比,拉伸件的高径比可提高9％左右,材料利用率可提高5％左右。对于方法兰圆筒件。采用方坯拉伸更具优越性,材料利用率可提高45％左右。 The deformation mechanism of billet in anisotropic steel plate is studied. Through a large number of experiments, compared the round billet, billet tensile force, ultimate tensile ratio, tensile member effective height and wall thickness variation. In the case of a larger draw ratio, compared with the billet billet, tensile aspect ratio can be increased by about 9%, material utilization can be increased by about 5%. For flanged cylinder parts. Billet stretching more advantages, material utilization can be increased by about 45%.
