Carbon Steel from Prereduced Pellets--Acid Practice.

NTIS: PB 240 138 :7 pages
Eleven steelmaking heats are described in this Bureau of Mines report in which acid practice was used to produce carbon steel from prereduced iron ore pellets. Furnace slags obtained with no flux addition to the charge became quite viscous as they cooled, which precluded pressure casting from a ladle. Lime was added to the furnace charge at two levels to eight of the heats to modify slag characteristics in the furnace, and to the ladle in two heats to further modify the ladle slag cover. Selected ingots from nine heats were successfully rolled on a commercial mill to produce No. 10 reinforcing bar.
