摘要
本文由结晶器摩擦力的新检测方法及其应用方法研究两部分组成。
     随着结晶器液压振动装置在连铸生产中逐渐推广应用,与之相关的结晶器摩擦力在线监测方法己成为一个新的课题。在此背景下,本文开展了液压振动方式下摩擦力检测方法研究。从理论分析入手,推导出摩擦力检测数学模型,并对该模型进行验证和误差分析;讨论了检测参数与液压振动参数间的关系,最后提出其在线应用方法。
     MDF异常特征和规律分析 以宝钢2号板坯连铸机生产中的结晶器摩擦力实测数据为基础,对应现场的漏钢、水口断裂等异常纪录,讨论了生产中采取工艺操作、工艺参数变化及异常发生时MDF及其均方根的波动规律及变化特征。
     MDF异常预报方法研究和软件的开发基于实测数据分析的结果,本文的最后开展了MDF应用方法的研究,应用BP神经元网络与斜坡、脉冲等辅助判据相结合的方法进行异常预报。对应着生产现场的异常纪录,对现场检测到的摩擦力数据进行离线预报,异常预报的结果证明了该方法是可行的。
This paper presents on-line measurement of mould friction(MDF) and the applications with MDF in continuous casting.
    With the spread and application of hydraulic oscillators in continuous casting, the on-line measurement method of mould friction is coming to a new subject. Under this circumstances, the on-line measuring method of mould friction is investigated in this paper. Based on theoretic analysis, a mathematic model of on-line measurement is built, and its correctness and error is discussed. At the same time, the relation between measuring parameter and oscillating parameter is investigated. Finally, the primary on-line measuring method is put forward in the paper.
    Analysis of characteristic of MDF abnormity Based on the measuring data of mould friction of continuous slab casting in steel plant, the fluctuation characteristic of MDF and its rootmeansquare has been studied on the unstable conditions, such as breakout, temperature system warning, abnormity of submerged entry nozzle, mould level fluctuation, and on-line change of slab width.
    Study on the prediction method of MDF abnormity and development of software for abnormal analysis Based on the above analysis, a prediction method for MDF abnormity has been built employing neural network and two abnormal models: ramp and puise judgments. A set of software of abnormal analysis of MDF has been developed. According to abnormal records of steel plant, the software can forecast accurately most abnormities, and it can make prediction several minutes ahead of temperature system warning. The results show that the method is dependable and it demonstrates remarkable potential for application in abnormal prediction.
