Carbon and Oxygen Usage in the EAF — Is More Always Better? (Room 402)

07 May 19
11:00 AM - 11:30 AM

Tracks: Direct Reduced Iron

Many steelmakers add carbon to the EAF, but most often do not critically evaluate their current practices. Carbon is viewed as a way to introduce chemical energy into the melting process. However, it can also have significant effect on other aspects of the furnace operation. This paper discusses the theory of carbon and oxygen usage, and presents examples of practices in common use. These practices are then discussed with respect to how they affect the overall steelmaking process with the intent of providing guidance to arc furnace steelmakers so that injection practices are cost-effectively and intelligently implemented.
