Policies all over the world encourage the high energy efficiency of processes and the reduction of greenhouse gas (GHG) emissions, classified as direct and indirect. Iron and steelmaking is energy intensive industry, which also contributes 30% of the direct global CO2 emissions (2007), triggered through the industrial processes [1]. This article focuses on the verification of the CO2 emissions distribution for the secondary steelmaking.The potential for reduction of these emissions depends on the following key factors of ladle logistics and temperature losses under consideration of the steel contact time, additions during tapping, treatment at the ladle furnace to compensate temperature losses, and ladle preheating.
