【Abstract】 In this paper, a new method to get the optimal furnace temperature of reheating furnace is brought up for the first time on the basis of the mathematical model of continuous reheating furnace. The objective function is the integral value of enthalpy increasing process of billet. The calculating results show that this method incarnates really the essense of optimal temperature raising process of billet and embodies sufficiently the principle of speedy reheating. The optimal furnace temperature makes reheating furnace not only save fuel sufficiently but also decrease the oxidation of metal to the greatest degree. So it makes saving fuel consistent with decreasing oxidation.更多还原
