摘　　要：讨论了三辊斜轧整体型翅片管的生产工艺,分析了工艺参数(轧辊压下量、斜轧角度、轧辊辊型等)对翅高及伸长率的影响规律。理论分析和实验结果表明:整体型翅片管最佳的成形工艺是:轧辊压下量3.2 mm,斜轧角度2.5°,轧辊咬入段16片,辗轧段10片,精整段4片。这对实际生产具有指导意义。The manufacturing technique of integral type tinned tube wltla tlaree-roll skew rolling was OlSCUSSetl. Jne influences of technological parameters （roll reduction, skew rolling angle and roll profile etc.） on the height of fin and elongation were analyzed. Theoretical analysis and experimental results show that the best forming process of integral type finned tube is as follows： the roll reduction is 3.2 mm, the skew rolling angle is 2.5, the section of bite is 16 pieces, the section of roll is 10 pieces, and the finishing section is 4 pieces. This has some guiding significances to actual production.
