Abstract

In the manufacture of cast iron titanium or an alloy containing titanium is added to the charge or to the molten iron and the titanium in the melt subsequently oxidized either by passing an oxidizing gas such as air or carbon dioxide through the melt or by adding a solid oxidizing agent, such as a carbonate or an oxide, to the melt. After the oxidation of the titanium hydrogen may be blown through the melt so as to coarsen the graphite in the iron. Instead of hydrogen, hydrogen-containing compounds such as steam or hydrocarbons may be used. If too much hydrogen is dissolved in the molten iron, the excess of hydrogen may be removed by blowing nitrogen, air, or carbon dioxide through the molten metal.
