The world's first 89 mm three-roll rolling tube in China metallurgical sadie production unit

On December 19, China metallurgical sadie complete equipment of henan linzhou phoenix co., LTD. 89 seamless steel tube rolling unit production weshuibao licensing pp-r pipe.The project adopts the MCC sadie independent sets of the world's first set of minimum diameter (89 mm) of the three roll six frame strip unit, the main technical indicators reached world leading level.Feng bao project is the world's first professional production of small diameter seamless steel tube three roll strip production lines, product specification range 32 mm to 89 mm, wall thickness 3 mm ~ 12 mm, designed annual output 200000 tons, produce axle, steering axle, bearing tube high-quality lightweight materials, used for nuclear power, oil industry supply high-end seamless steel tube.China metallurgical sadie giving full play to the advantages of more professional steel engineering system integration and core equipment manufacturing capability, self-developed MPM core production technology and equipment, will for the first time in the world three roll six frame strip unit successfully applied in small diameter seamless steel tube production, adopting the world's most advanced lateral roll change type three roll six frame and rolling mill and 28 frame tension reducing mill, equipped with a complete process control model, hydraulic servo roll gap control system with high response and high automation control system and rolling mill & other;Sharpening rolling & throughout;, tension reducing mill of wall thickness control and CEC control function, also adopted the China metallurgical sadie self-developed high speed data acquisition system and monitoring system, visual monitoring and digital analysis was carried out on the production process, production technology, control technology reached world leading level.The project also innovative production technology, the realization of the production of small diameter seamless steel tube & other;As heat generation throughout cold &;, reduce the energy consumption of traditional cold rolling\/cold drawing process, the metal consumption and environmental pollution, which laid a foundation for application in domestic comprehensive promotion and provides technical guarantee for the iron and steel industry to the transformation and upgrading of green manufacturing, intelligent manufacturing set up the pole.The project since 2017, when the heat load on October 1, since the successful commissioning, through trial production period for continuous improvement and optimization in two months namely, fully realize the continuous and stable, high flexible production rhythm, MPM unit production gradually play the advantages of high quality, high efficiency, high yield, fill in the blank of domestic high-grade small diameter hot rolled seamless steel tube industry.????(the original title: the world's first 89 mm three-roll rolling pipe unit in China metallurgical sadie) (source: machinery expo)
