A reheating furnace is a facility of a rod mill plant where a billet is heated to have uniform target temperature so that it can be milled to produce wire. Since the reheating furnace consumes very large amount of energy to heat up the billets, it is very important to find an optimal temperature setting in the furnace for energy saving. This paper proposes an opti mal temperature setting method based on FEM (Finite El ement Method) and uDEAS (Univariate Dynamic Encod ing Algorithm for Search). The energy consumption by the proposed scheme is reduced meaningfully.
