The article describes the construction of a 20 mm diameter grey cast iron ingots continuous casting laboratory line. This line is made of three main units: melting unit (induction furnace), casting unit and the pulling unit. In order to improve the homogeneity of the microstructure of ingots (by applying forced convection of liquid metal during the crystallization process) in this case a crystallizer system generating the forced movement of liquid metal based on a system of electrical power windings of the AC specific frequency. This solution allowed to obtain a homogeneous microstructure of the continuous casting of cast iron EN-GJL-200 species.
