oxygen-enriched combustion
burning technology
Cold rolling continuous
annealing furnace steel strip
temperature mathematical
modeling
Integrating five procedures
including cleansing, inspection,
sorting, etc. into one procedure,
hence significantly improving
the thermal efficiency of
annealing
Recovery and reuse of waste
heat from rolling reheating
furnace fume
