“…The advantages include the reduction of high-frequency interference and transient variations. Therefore, this technique of increasing the stability margin is called damping with the suppression of high frequencies [18]. In Figure 5, the aperiodic link can be found as block 2.…”

The article presents studies on the electromechanical system of a metallurgical horizontal looper in the steelmaking industry. During the operation of this unit, parameters in the system changes due to variations of length and mass of the steel strip, these variations significantly change elastic properties and reduce moments of inertia. Various methods of combating elastic vibrations in electromechanical systems are analyzed in this article. The article presents a description of experiments with a horizontal looper. A mathematical model for two extreme positions of the unit was developed based on experimental results. Simulation experiments were made and their results are presented. A new control system structure is proposed to reduce vibrations in the electromechanical system of a horizontal looper. A power-up sensor, adjuster and velocity derivative feedback were added into the model structure. The proposed feedback link structure takes into account the change of steel strip length. From the experimental data it follows that the proposed system provides effective damping of mechanical vibrations in the steel strip if its length during operation is changed.

Reducing mills in piece-reduction at the moment of capturing the pipe’s front end and on the rear end exit are exposed to increased dynamic loads. However these processes at present time are not fully researched. The relevant problem is to decrease dynamic loads in the clamp engine, to increase reliability and durability of the clamp on the basis of the mill’s production growth on the account of pauses decrease, rise of the production amount, and reducing in pipe costs. In the article the results of the study to define a part lifetime in the reducing mill stand have been presented. A part lifetime was calculated in month for more convenient comparison with the production data. The results have been hand over to JSC “PNTZ” for implantation.
