NVH Analysis of Mold Oscillation Devices

Mold oscillation device is one of the most important systems within a continuous casting process, which is necessary to minimize friction /sticking of the solidifying shell, to avoid shell tearing /liquid steel breakouts, and to elimination of surface/internal defects in the cast product. In order to meet the increased demands on exact curve profile match, billet/slab quality, productivity and functional safety, a precise oscillation and a high level of flexibility with respect to profile, stroke, frequency and their optimal combination are definitely essential .

On the other hand, fatigue issues and the thermo-mechanical coupling deformation of components of the device caused by the sinusoidal and non-sinusoidal excitations should satisfy the use requirements. Simulation aimed to these devices is practice-oriented and needs extensive experience and relatively sound knowledge across a wide range of technologies.

Generalety offers the complete simulation and solutions for the mold oscillation devices technically including trajectory analysis, vibration analysis, dynamic stress analysis, fatigue life prediction and so on, well based on our effective and timely service for different types of devices from several customers.

For instance, the dynamic stress induced by oscillation is simulated for entire structure of the device, and corresponding FRF analysis indicates which part contains the high stress zone, which element ( location) has the highest stress level. These results, combined with the integrity, reliability and performance goals of the device, will provide a practical basis for the dynamic behavior design of the device and the selection of a better oscillation frequency range.

    I’ve been surfing online more than 2 hours today, yet I never found any interesting article like yours. It is pretty worth enough for me. In my view, if all webmasters and bloggers made good content as you did, the net will be much more useful than ever before.
    I’ll immediately snatch your rss as I can’t find your e-mail subscription link or newsletter service. Do you’ve any? Kindly let me recognize in order that I may just subscribe. Thanks.
