Abstract

Modern devices for continuous casting (cc.) of steel - despite the shape of cross-section of cast billets, are equipped with electromagnetic systems for stirring liquid core inner the solidifying steel shell. Depending on the grade of cast steels, requirements for isotropy of chemical composition and properties along transverse and longitudinal cross-section of cc. billets, there are applied various schemes in placing systems inducing motions (rotation) of the liquid core.Based on the analysis of samples after etching, being cut out as continuous casting billets with square cross-sections, the following was stated: the surface of the equiaxed crystal zone, values of overheating and the total surface - on which internal structural defects can be observed in continuous casting of billets.

Keywords: steel, electromagnetic stirring, continuous casting, defects of billets.
