METHOD OF STEEL CONTINUOUS CASTING Russian patent published in 2010 - IPC B22D11/51 

FIELD: metallurgy.

SUBSTANCE: method of steel continuous casting includes steel feeding into swinging ingot-forming equipment, feeding of slag-forming mixture to melt meniscus, drawing from ingot-forming equipment of uninterruptedly-casted blank with specified rate. Swinging of ingot-forming equipment is implemented according to equation of complex sinusoidal vibrations with different amplitudes and frequencies, consisting of sum of the first and second harmonics. Ratio of amplitudes of the second and the first harmonics is defined through coefficient χ, selected from the range 0.1≤χ≤0.25. Rate of ingot-forming equipment swinging is defined by equation of motion. In equations it is taken into account chemical composition of steel.

EFFECT: there is provided consumption increasing of slag-forming mixture between sinterskin of uninterruptedly-casted blank and walls of ingot-forming equipment up to 40%, reduction of friction between sinterskin of blank and walls of ingot-forming equipment up to 25%, reduction of production offal.
