摘    要:针对水泥生料细度难以在线测量,无法采用传统控制方法控制的问题,结合专家知识和操作经验,提出基于案例推理技术的水泥生料细度智能优化控制方法。根据立磨内选粉机转速、通风量、研磨压力等信号,采用案例推理方法自动调整选粉机转速,从而使水泥生料细度满足质量要求。该智能优化方法在某水泥厂应用结果表明:基于案例推理技术的智能优化方法与传统控制方法相比,生料细度合格率提高了11%。

Abstract: Fineness of raw material is a key parameter in raw grinding process. It is difficult to measure the fineness online, and unable to achieve ideal effect by adopting traditional control method. To solve these problems, combining the expert knowledge and operation experience, an intelligent optimization and control method based on case reasoning was designed. This method adjusted the separator speed automatically by using case reasoning method according to process parameters, such as ventilation and grinding pressure. Application in a cement plant shows that the intelligent optimization and control method based on case reasoning can increase product quality by 11% compared with traditional manual method.
