摘要针对无缝钢管张力减径头尾增厚缺陷,基于管端壁厚补偿方案与头尾削尖技术,预设计削尖荒管的削尖参数,借助ABAQUS有限元软件建立了张力减径全过程仿真模型并通过现场试验验证其准确性。通过单一控制变量法研究不同削尖量、削尖长度等参量对张减头尾增厚缺陷所造成的管端切损长度的影响及壁厚补偿规律,通过补偿效果不同,建立“全补偿区”、“过补偿区”和“不合理区”等评判依据。考虑无缝钢管生产工艺长流程、多工序的特点及钢管尺寸在不同工序、道次、工具下的遗传特性,提出连轧-张减多工序联合控制的削尖荒管补偿控制策略,给出削尖荒管削尖参数的设计准则,并基于模拟壁厚数据推导得出削尖量有效取值范围预测模型。建立削尖荒管在张力减径咬钢-稳定轧制-抛钢全过程的头尾削尖补偿控制模型,对比分析补偿前后无缝钢管截面形状及尺寸精度,结果表明削尖荒管补偿控制策略具有显著的缺陷抑制效果。将削尖荒管补偿控制策略拓展应用于3种不同规格、不同延伸系数的钢管张减过程,验证了头尾削尖补偿控制方法的适用性,以减少60%的管端切损长度为衡量标准,各规格张减产品的削尖量均存在某个有效取值范围。对于提高无缝钢管产品质量稳定性及成材率具有一定指导意义和行业实用价值。

Abstract：Aiming at the thickening defects on the seamless pipe ends during tension reducing,basing on the compensation scheme of the wall thickness on pipe ends and the head and tail sharpening technology,the sharpening parameters of the sharpened pierced billet are pre-designed. With the help of ABAQUS finite element software,the whole process simulation model of tension reduction was established and its accuracy was verified by field test. The effects of different sharpening amount and sharpening length on the cutting loss length of the ends of pipe and the law of compensation of thickening wall were studied by single control variable method. Establishing the judgement basis of "full compensation area","over compensation area" and "unreasonable area" with different compensation effects. Considering the characteristics of long process and multi-process of seamless pipe production process and the genetic characteristics of pipe size under different processes,different passes and different tools,a control strategy of sharpened pierced billet compensation of multi-process joint control of tandem rolling-tension reducing is proposed. The design criterion of cutting parameters for pierced billet is given and the prediction model of effective value range of sharpening amount is derived basing on a large number of wall thickness data. The compensation control model of the head and tail sharpening of the sharpened pierced billet is established during the whole process of tension reduction,biting steel-steady rolling-casting steel. The section shape and dimensional accuracy of seamless pipe before and after compensation are compared and analyzed. The results show that the compensation control strategy for the sharpened pierced billet has significant suppression effect of defects. The strategy is extended to the pipe process of tension reduction with different specifications and extension coefficients,the applicability of the head and tail sharpening compensation control method is verified. Taking the length of pipe end cutting loss reduced by 60% as the measurement standard,there exists an effective value range for the sharpening amount of tensioning products of various specifications. The research has important guiding significance and industry practical value for improving the quality stability and yield of seamless pipe products.
