Melting and casting conditions necessary for production of the so-called S-H cast iron were studied and the following results were obtained in the scope of the present experiments:
1) The suitable melting temperature was 1350°C. to 1450°C., at which the cast iron melt was to be treated with the slag.
2) The suitable casting temperature of the cast iron melt, treated by the slag, was 1250°C. to 1300°C.
3) The basicity of the slag (CaO/SiO2) should be over about 0.4.
4) The suitable amount of the slag was about 15% of the cast iron melt.
5) The suitable time of contact between the cast iron melt and the molten slag varied with content of the titanium oxide in the slag. The larger was the latter, the shorter became the former.
