摘　　要：简述了宝钢460无缝钢管项目热轧线的技术设计。对比当今世界上最先进的同类大口径三辊连轧管机组,分析了宝钢460三辊连轧管机组的技术进步:加大原料管坯直径;提高锥式穿孔机的轧制力矩,增大穿孔机轧辊直径,并在进料侧使用管坯预旋转装置;减少连轧管机及定径机的孔型系列;提高连轧管机的最大允许轧制力;采用12机架定径机,最后3个为可调型机架;应用了液压小舱技术及CARTA工艺控制软件包等。The technical design of the hot-rolling production line for Baosteel 460mm seamless steel tube project is briefed.Compared with the most advanced large-caliber three-roll mill unit of its kind in the world,Baosteel three-roll mill unit for 460mm seamless steel tube was analyzed in terms of the technological progress it has made.The progress covers an increase in steel pipe billet s diameter,an improvement in cone-piercing machine s rolling torque,an increase in diameter of the piercing machine s roll,the use of the feeding tube pre-rotation device, a decrease in the number of rolling tube mill machines and series pass of sizing machines. To increase the maximum allowable rolling force of the pipe rolling machine, the 12 rack sizing machine was used and the last three frames were rack-adjustable. Besides, the hydraulic capsule technology and CARTA process control software package were used.
