Abstract
The introduction of pipe rolling from continuous-cast bullet on the TPA 220 piercing mill, with an expanded range (up to a diameter of 245 mm, as against the previous limit of 219 mm) and increase in pipe length, is described. The mechanical parameters of the mill are measured and assessed. Options for further modernization of the mill and the production of thin-walled pipe with a diameter/wall ratio of more than 30 are outlined.
