| description | The advantages of using CO2 for the decarburization of high alloy steels have
been recognized from environmental and economic view points. The present
paper presents the heat and materials balances in the decarburization process
with the introduction of CO2 as a diluting gas in Electric Arc Furnace (EAF)
process for steel production. The aim is to optimize the amount of CO2 and
the materials requirements, which includes the addition of scrap, hot metal
and coolant. These estimations are also important to control the bath
temperature, thereby prolong the lifetime of the refractory lining of the
furnace. The present calculations enable an optimization of the CO2:O2 ratio
and materials input in the decarburization of carbon steel melts. Another
important extension of the work is the possibility to enhance the addition of
hot metal during steel making process. The present results show that addition
of up to 20% hot metal is likely to the energy loss due to the introduction
of 50% CO2 for a 110 tons EAF resulting in the saving of electric energy. |
