Antykuz O. Substantiation of parameters of movement of a mold of continuous casting machine of preparations and improvement of its design.

Object - oscillation mechanism of continuous slab caster's mould. Goal - slab casters mould structure and oscillation mechanism improvement. Investigation methods and equipment - simulation methods of slab mould reciprocal motion consider with basic theses of machines for metallurgical industry theory, vibrometry methods, methods of mathematical statistics, physical and mathematical simulation, computer with real-time operating system, portable vibration analyzer, accelerometer. Theoretical and practical results - relevant scientific-and-engineering problem of theoretical and experimental substantiation of slab mould movement (amplitude, oscillation frequency, non-sinusoidal coefficient, acceleration curve's shape), improvement of it's construction is solved by means of liquid metal level sensor arrangement explanation and mould equipping with two three axial accelerometers. Conditions of shell formation are improved and the slab quality is advanced by oscillation marks depth decreasing for 15%. Novelty: For the first time the frequency of mould reciprocal motion influence on standing wave appearance in meniscus theoretically and experimentally determined; non-sinusoidal mould motion law is improved by acceleration curve smoothing, that's allows to except acceleration sharp leap during mould movement direction change; it was established, that standing waves development process on the meniscus in the slab mould promote to the slag movement to the narrow mould faces phenomenon and exposure of the meniscus. This provokes increase in 2 to 2,5 times of wave oscillation amplitude and slag particles involving. The degree of implementation - industrial operation on the slab casters oscillation mechanisms on "Novolipetskiy metallurgical plant", "MK "Azovstal". Sphere of usage - metallurgy, machine-building.
