STEEL FROM URBAN WASTE.

A series of steel heats, one low-alloy and nine carbon, was made in a 1-ton arc furnace from ferrous scrap from incinerated refuse, steel cans, and detinned steel cans, both alone and blended with heavy-melting scrap. Two additional control heats, one of carbon steel and one of low-alloy steel, were made from electric furnace heavy-melting scrap to provide comparative data. The steel products were cast into two 4- by 4-inch nominal 50-pound ingots; in most heats, an 8- by 8-inch nominal 750-pound ingot was also obtained. Tests of these ingots indicated that reinforcing bars of acceptable quality can be made from urban refuse components such as steel cans. 6 refs.
