Increasing the Durability of Separating Rolls During Rolling Ribbed Bars in the Three-Strand Technology
The paper presents the results of investigations aimed at enhancing the durability of slitting passes in the process of three-strand rolling of 16 mm-diameter ribbed bars. Using the Forge2011® computer program, numerical modelling of the rolling process was carried out in order to examine the variat...
