Abstract

<PICT:0967337/C6-C7/1> Spheroidal-graphite iron is produced by injecting the appropriate reagents under gas pressure into the molten metal in the well of the cupola or other melting furnace. As illutrated, delivery tube 3 is connected to a suitable source of supply and passes through the lining 2 of the cupola emerging adjacent to tap hole 5. Gas pressure is applied continuously while melting is in progress, but treatment materials are fed only while metal is being tapped. Specification 808,293 is referred to.
