Abstract
The process to change the strip form is presented for the continuous metallurgical unit consisted of the forming mill, the butt—welt pipe mill, the calibrated mill and the shaping mill. At the Metal Forming Departure of National University of Science and Technology MISIS, the next topics are developed actively: (1) The new caliber designs for forming units lines of different configurations; (2) The computer modeling of geometrical parameters; (3) The equipment manufacturing in the accordance with the modern technologies; (4) The determination of the strained–deformed state of pipe skelp during the shaping processes taking into account the deformation conditions; (5) The determination of energy-force parameters and their analyzing. Techniques based on special prints to determine the forming contact conditions are presented for the different schemes of speed conditions of pipe skelp forming in the roll caliber. Physical and computer modeling are used to study the continuous forming processes. The results of experimental investigations and the contact surfaces parameters are presented in this article. As part of the production facilities expansion the proposals have been developed to upgrade Continuous Forming Mill TESA 219-406 for the production of the pipe the 406 mm diameter pipe with the 10 mm thick wall.
