摘要为了实现钢坯加热炉炉温的优化控制，研究了燃料流量的模糊专家控制，空/燃比的极值寻优以及炉膛压力的模糊pi控制策略。

• In order to realize the optimum control of the temperature in the billet reheating furnace, the fuzzy control and expert control of the fuel flow, the optimization extreme of the air/fuel ratio, and the fuzzy PI control of the pressures in furnace are discussed.
