The steel rolling process consumes a tremendous amount energy, for which the average thermal efficiency is only 20% ~ 30%. Around 70% ~ 80% of the entire energy input required for such process has traditionally been lost in the environment, and at least 30% of this lost energy is carried by flue gas. Especially for steel rolling mills without a regenerative combustion system, it is important to recover the waste heat from the flue gas coming out of the billet reheating furnace.
