The paper presents the research results of horizontal continuous casting of ingots of aluminium alloy containing 2% wt. silicon (AlSi2).

Together with the casting velocity (velocity of ingot movement) we considered the influence of electromagnetic stirring in the area of the

continuous casting mould on refinement of the ingot’s primary structure and their selected mechanical properties, i.e. tensile strength, yield

strength, hardness and elongation. The effect of primary structure refinement and mechanical properties obtained by electromagnetic

stirring was compared with refinement obtained by using traditional inoculation, which consists in introducing additives, i.e. Ti, B and Sr,

to the metal bath. On the basis of the obtained results we confirmed that inoculation done by electromagnetic stirring in the range of the

continuous casting mould guarantees improved mechanical properties and also decreases the negative influence of casting velocity, thus

increasing the structure of AlSi2 continuous ingots.
