Rational solution in the organization of synthetic cast iron steeling

The effect of the increased proportion of scrap steel in the raw material was manifested by a significant increase in Brinell hardness HB in synthetic gray iron, while the tensile strength was consistent with conventional gray iron. A higher proportion of steel scrap (average 34.4%) showed a higher degree of maturity of gray cast iron GR by about 10% and a higher quality number of GB - 100.64. Additionally, the positive effect of SiC in the charge on the reduction of wedge-shaped and free cementite in the structure of the resulting synthetic cast iron is known.
