  • Analysis of groove rolling of a round bar
    Pepelnjak, Tomaž ; Štarkel, Sebastjan
    Steel making plants having great diversity of several hundred different rolled profiles, bars and strips in their production program produce also various dimensions of round steel bars. For those ... bars the roundness is one of the the most difficult attainable geometrical parameter. The process of rolling set-up gets quite complicated and needs to be computer aided. The existing process is based on use of computer program for groove design and calculating rolling parameters, called Wicon, but it gives only rough values needed for rolling mill settings. In order to obtain the proper geometrical and kinematic settings, calibration experts still have to rely on their experiences. In the paper, the procedure of the rolling mill set-up is presented. The technology set-up of the Ø32 mm bar rolled with groove shapes was determined by Wicon. The rolling process was analysed by the FEM programme in order to verify the setting of the groove shapes. Both concepts were compared with rolled bars obtained in real production. Finally, the guidelines for further computer assisted research work were stated in order to improve the bar tolerances and stabilize the rolling process.
