Hydrogen Control of Large Bottom Poured Forging Ingots at Ellwood Quality Steels (Room 414)

Hydrogen removal and hydrogen pickup during liquid steel processing at Ellwood Quality Steels are studied in detail with particular emphasis on the effect of Electromagnetic Stirring (EMS) on hydrogen removal. The results of this work indicate that the Ultra-Low Hydrogen Practice implemented at EQS allows for consistent production of high-quality, large cross-section bottom poured steel ingots with hydrogen content of less than 1.5 ppm.
