Influence of Hollow Electrode Ar-CO₂ Injection on Carbon Content in Ladle Furnace

Abstract:

The argon and carbon dioxide co-injection tests were carried out with low carbon steel melts of 100 kg in a multi-function direct current ladle furnace (DC-LF) equipped with a hollow graphite electrode. It is shown that, the electrode consumption rate and the carburetion rate decrease when Ar-CO₂ gas mixtures are blown into the furnace. The carburetion rate is 3.6×10^-6 per minute for the steel heated by conventional LF, and is 1.35 and 3.22 times of the heats blown 85%Ar-15%CO2 and 80%Ar-20%CO2, respectively. The carburetion rate is reduced by 25.8% at least than normal LF. The more the carbon dioxide content in the gas mixtures is, the less the carburetion rate and the electrode consumption rate are. With the increasing of the electrode consumption rate, the carburetion rate becomes bigger.
