Comprehensive dynamic model for BOF process: a glimpse into thermal efficiency mechanisms
J.-C. Huber, J. Lehmann and R. Cadet(Published online: 9 April 2008)
Abstract
Understanding thermal transfer mechanisms in BOF converter is a
key for higher energy efficiency, involving higher production capacity
and lower CO2 emissions through low hot metal ratio capability.
The developed model achieves a coupled description of the major
phenomena: refining reactions, mass transfers between phases, scrap
melting, post-combustion, slag formation. The calculated exhaust
fumes enthalpy is fitting well the measured thermal balance trials with
industrial converter when implementing a detailed description of the
post-combustion. This model, compatible with real-time use, is also a
valuable tool for further improvement in dynamic control of the process.
