摘　　要：转炉汽化冷却系统中,控制核心是汽包水位的控制。分析了传统双冲量及三冲量控制方法不能满足转炉汽包水位控制的原因,并针对转炉生产的特点,提出了一种结合转炉生产状态的分段式控制方法,其主吹氧阶段采用模糊控制算法实现对汽包水位的控制。将汽包水位和水位变化率进行模糊化计算,将模糊化计算的结果,作为汽包补水流量调节系统的输入,动态设定给水流量,以达到最终稳定汽包水位的目的。Control of drum water level is the kernel in converter vaporization cooling system. The reasons why traditional control methods, such as two-element and three-element control, can not satisfy the control of converter drum water level are analyzed. Based on characters of BOF production, an improved fuzzy control algorithm is proposed. In main oxygen-blown stage, fuzzy control algorithm is used to achieve control of drum level. Level and its change rate are fuzzified, then calculation results are used as the input of drum water flow adjustment system and feed water flow is dynamically set, so as to stabilize level of drum.
