摘要：

The tube rotation method(TRM) refers to the rotational movement of steel tube about its axis as well as translation in rolling direction in stretch reducing rolling process.The influence of the TRM on transverse wall thickness precision of seamless steel tube was studied.Thickness distribution of the TRM was obtained by superimposing the thickened amount of single pass rolling.Results show that the TRM can effectively improve the evenness of thickness distribution.In order to analyze the influence mechanism of the TRM,the finite element method was adopted to simulate the thickness distribution in stretch reduction process.Results show that the TRM changes the roundtrip flow between two fix places of conventional stretch reducing and inhibits the directional accumulation of metal.In addition,the TRM has a correction effect on thickness cusp.All these advantages of the TRM help to improve the transverse wall thickness precision of seamless steel tube.
