    Load Control Operational Correction of a Blast Furnace Based on the Correlation Models
    (Croatian Metallurgical Society (CMS), Zagreb, Croatia, 2024) Shvachych, G.; Mamuzich, I.; Selegej, A. M.; Мoroz, B.; Kadylnykova, T.; Pobochii, Ivan A.; Мoroz, D.; Friman, Y.
    ENG: The paper uses regression analysis to research the movement dynamics of charge materials along the paths of a blast furnace coneless loader device. The research’s main goal is to consider two main factors when optimizing the loading process of the blast furnace - the opening degree of the charge shutter of the loading device hopper and the inclination angle of the distribution tray. That approach allows the optimization of the loading impact, taking into account the current change in the granulometric parameters of the blast furnace charge. A model for determining the dynamic parameters of the charge flow in the case of its movement along the paths of the blast furnace coneless loading device has been developed.

    Mathematical Model of a Pipe Welded Connection under Vibration
    (Дніпровський державний технічний університет, Кам’янське, 2021) Balakin, Valeriy F.; Kadylnykova, T.; Savkyn, S.
    ENG: The article discusses the theoretical foundations for improving pipe welding processes through the use of vibration. A mathematical model of a pipe welded joint has been constructed, which makes it possible to determine the residual stresses in welded seams exposed to vibration during the welding process and the optimal time of vibration exposure. The constructed mathematical model makes it possible to obtain analytical values of residual stresses for each specific processed object having data on the natural vibration frequency, vibration damping coefficient, amplitude and frequency of the driving force of vibration.
