Rodionov M. Justification a rational way of balancing the mold oscillation mechanism of continuous casting machine

The thesis study carried out a rational way of adjusting the lever mold oscillation mechanism of profiled continuous casting machine to increase its service life. The concept of relationship factors, which determining the force loading units and joints, with the nature of bearings wear was formulated. The intensity of wear of the mold oscillator bearings, running in the rocking motion, with the variable component of the reaction forces in the corresponding joints and supports was established and practically confirmed by the tests on laboratory and industrial stands. Using mathematical modeling of the laws of loading joints and supports corresponding to the various modes of mold operation and adjustment were defined frequency intervals of mold oscillation and the air pressure in the unloading devices which correspond to the appearance alternating and shock loads in bearing units. Based on the obtained results was provided a method of adjustment the mold oscillation mechanism, which based on the criteria for exclusion and minimize alternating shock loading of bearing joints and supports. This method is based on the selection of the air pressure in the unloading devices according to the predetermined mold oscillation frequency. Industrial introduction of mold oscillation mechanism adjustment method allowed to increase service life of this type of mechanisms by 25-30%. Experimental and industrial testing of the solutions confirming their efficiency and reliability, which was proved in the introduction act.
