摘　　要：根据斜轧管机组存在轧制周期长、产量低的情况,设计一种新型的双芯棒限动机构。介绍该新型双芯棒限动机构的结构组成,分析其优势,并介绍实际应用情况。分析认为:其设计的新型双芯棒限动机构,即一根芯棒在轧制中,另一根芯棒预穿毛管的机构,可以实现芯棒的实时控制,缩短芯棒循环的时间,提高轧制节奏,延长芯棒的使用寿命,提高钢管产量以及成材率,降低生产成本。Addressing the shortcomings staying with the rotary-rolling pipe mill such as rather long rolling cycle and low output, a new type dual-mandrel-retaining system is designed. Described in the paper are the main aspects of the said system, including the structural composition, the advantage analysis and the actual application result, etc. It is regarded via the analysis that employment of the said system which gets one mandrel being used for rolling, while the other being pre-piercing the shell shall bring about such advantages as real-time control of the mandrel, shortening the mandrel circulation time, enhancing the rolling cycle, increasing the mandrel service span, increasing pipe output and yield, and reducing the production costs.
