This paper examines the impact of charging wet and oxidized material on the quality of cast iron,
quality SL20. In consideration were taken the same products obtained from 3 melts. For the
production of the first melt wet and oxidized charging components in quantity of 60 % were used, for
the second one quantity of 20 % of oxidizied and wet charging components were used, and for the
third one dry and non-oxidized material were used. After pouring and solidification of castings,
castings had been machined and differences were determined. After examination highly promoted gas
porosity were observed in the castings poured from the first melt
