Optimizing the continuous production of electrowelded pipe

Attention focuses on improvements in the calculation of the basic roller-groove parameters and the selection of an optimal configuration in converting the strip into pipe. The basic characteristics of pipe-electrowelding systems are presented. The influence of the shaping system and the configuration of the equipment on the energy parameters of pipe rolling is investigated. To reduce the number of driven shaping cells in the mill from 8–10 to four, recommendations are made regarding the grooving system and the mill composition. To this end, shaping along the descending trajectory of the lower generatrix is also recommended.
