Secondary Pig Iron from Shredded Auto Scrap.
NTIS: PB 226 101 :9 pages
The Bureau of Mines has been involved for several years in the development of processes for the recycling of solid wastes. As part of this program, a project was initiated to determine the feasibility of producing secondary pig iron from auto scrap. During the test period, 86,000 pounds of shredded auto scrap, along with petroleum coke and fluxing agents, was charged to a submerged-arc furnace of 1 ton nominal capacity. Eighty-eight thousand pounds of pig iron, with an average carbon content of 3.90 percent and an average copper content of 0.2 percent, was produced at an electrical consumption of 512 kw-hr per net ton. A cost estimate of the process showed that the pig iron might be produced at a cost of $57 per ton.
