The steelmaking process involves converting liquid iron into steel via basic oxygen furnace (B0F, also known as converter) or melting scrap steel and/or direct reduced iron (DRl) in an electric arc furnace (EAF).

Recovery of BOF gas is the single most energy-saving improvement in the BOF proceSs, making it a net energy producer. The BOF gas containing approximately 70-80% carbon monoxide(CO) is usually recovered in gas holder for future use.

On-line instruments especially exhaust gas monitor are used to optimize operations of an EA. Benefits of it include reduced electricity consumption, shorter power on times, increased productivity a decrease in production costs, a reduction of electrode consumption, reduced natural gas, oxygen and carbon consumption, and are duction of refractory wear.
