In the high-tonnage, low-margin business of electric arc furnace (EAF) steelmaking, incremental improvements can contribute significantly to earnings. Feedback of process information to the operator and engineers is the key to continuous improvement of the operation and maximizing earnings. In many EAF operations, the only cost indicators from process feedback consists of electrical energy, oxygen and natural gas consumption along with optimization indicators such as power-on time, tap-to-tap time, and yield. In modern EAF operations, the total amount of energy lost through the off-gas (both sensible and calorific heat) can be up to 45 percent of the total energy input to the EAF. Monitoring of the energy inputs and losses continuously using Smart-Gas allows EAF operators and engineers to identify periods of the operation where the energy transfer efficiency to the steel is low. During these periods the energy input to the EAF is underutilized and inefficiently used. This paper describes the use of the Smart-Gas system, developed by WorleyParsons GCT, as a simple tool for tracking EAF energy efficiency and providing real-time feedback to steel-making operations. The Smart-Gas system is low maintenance, consists of low-cost instrumentation, and provides continuous, real-time information on the energy efficiency of the EAF.
