Optimal Heating And Energy Management For Slabs In A Reheating Furnace, Wei-Hsin Chen, Mu-Rong Lin, Tzong-Shyng Leu
Journal of Marine Science and Technology
Optimal heating for slabs in a reheating furnace is investigated numerically to aid in managing energy consumption of the reheating furnace in a hot strip mill, where an arctangent function is applied as the heating curve. Particular attention is paid to the relationship among the temperature uniformity, discharging target temperature and retention time of the slabs. The results indicate that the temperature difference between the slab surface and the core increases rapidly in the initial period and the maximum value of the temperature difference is close to the inflection point of the heating curve. After that, the internal temperature tends …
