Research on effect of the performance of large diameter and thin wall seamless steel tubes by skew rolling and pilger rolling
Research is made on effect of the performance of large diameter and thin wall seamless steel tubes by skew rolling and pilger rolling through the test of chemical composition,tensile,elevated temperature tensile,hardness,series impact,and metallographic ofφ711 mm×24 mm size seamless steel pipe produced by the skew roller andφ 813 mm×28 mm size seamless steel pipe by Pilger roller.The research results indicate that,under the similar rolling ratios,pipes by the two rolling methods have no effect on performance of the room temperature strength,high temperature strength,and hardness.However,The 15CrMoG seamless steel pipe produced by the skew rolling method has smaller differences in transverse and longitudinal properties and better impact toughness.
