ELECTROHYDRAULIC SYSTEM FOR AUTOMATIC GAGE CONTROL (AGC) FOR TANDEM COLD MILL PLANT IN STEELWORKS SMEDEREVO

摘要

There is a problem with elastic deformations of a rolling mill stand and deviations in the output thickness of the strip. Another problem is very similar and it means that the inhomogeneity of material of the strip leads to a deviation in the output thickness of the strip. Therefore, the goal was to achieve increased rigidity of the rollers in tandem rolling strips. Flattening and flexion of the rollers, along with the elasticity of the system of rollers, can cause deviations in the output thickness of the strip from desired thickness.
