Prospect of Future Development Direction of Mandrel Mill Pipe-rolling Technology

Elaborated here in the paper is the present situation of the development of the mandrel mill pipe-rolling technologies at home and abroad,and also forecast is the future development direction of the technologies.Although the mandrel mill technology,particularly the three-roll mandrel mill technology is taken as the main development direction to eliminate the backward production capacity and realize the transformation & upgrading of the seamless steel pipe industry,there are till certain technical bottlenecks with it.From the perspectives of improving efficiency,reducing consumption,intelligent manufacturing and green production,it will be the trend for seamless steel pipe-making field to meet the transformation development demand and maintain the long-term and stable development in the future to solve the bottlenecks and common problems of the hot-rolled seamless steel pipe technology by using the-state-of-art technology,intelligence and newly-developed equipment,and developing a new generation mandrel mill technology as featuring high-efficiency,high-quality,greenness and intelligence.
