Abstract

In this article, research was conducted on low-alloy steel alloy 35XGCL (analog is JIS G 5111). Research is aimed at reducing the amount of gas pores and non-metallic inclusions in the liquid alloy. This process was carried outside of furnace. SEM/EDS analyzes were conducted on each experimental sample obtained during the research. In the research, the analysis of the effect of Al and Zr elements on reducing the amount of oxygen and nitrogen in the liquid alloy is presented. For experiments, the alloys were melted in an electric arc furnace. Experiments were conducted with different amounts of Al and Zr. As a result, ZrO2 and Al2O3 were formed. Processing in an argon flow after exposure to the elements increased the possibility of cleaning from largesized (>7 μm) inclusions. At the end of the research, the cleaning of the alloy from gas pores and non-metallic inclusions led to a significant improvement in mechanical properties.
