Thermal Efficiency in Steel Reheating Process

الملخص

In this study, the energy consumption by the
process of steel billet reheating in an industrial steel reheat
furnace at the Libya Iron and Steel Company (LISCO) is
considered. It is known that in the steel industry, one of the
processes requiring the most energy is the process of
reheating the steel prior to hot rolling. A comprehensive
mass and heat balance was performed on the furnace, taking
into account all actual entering and exiting furnace
parameters. Furnace thermal efficiency was found to be low
and heat losses from different areas of the furnace were
considerable.
