Abstract

The subject of the research is the production of high quality long products. A literature review is presented, which includes some features of the production of bars without additional longitudinal forces, a description of the effect of tension and/or back dam on the quality of the rolled products. The formulation of the problem of modeling rolling bar simultaneously in three stands is completed. The adequacy of the presented model is shown by comparing the simulation results and indications from the rolling mill. The error in the spreading did not exceed 0.4%, at the torque of rolling 11%, which is satisfactory convergence. Based on the developed model, a design experiment was planned and performed on the effect of the mismatch of continuous rolling speeds on the process parameters. The regression equations are obtained that describe the patterns of the influence of mismatch of rolling speeds on the technological parameters of the process.
