【摘要】：近年来伴随着中国钢铁市场需求下降,钢铁行业产能严重过剩,钢铁企业的盈利难度越来越大。作为国内领先的钢铁企业,必须抓住这产业结构调整的关键时刻,提升管理水平。研发轧辊管理系统可以形成统一的轧辊管理模式,使生产单元更加合理、经济地使用轧辊,发挥轧辊的最大使用效益,降低吨钢消耗轧辊毫米数,提升轧钢生产质量。论文研究了现有轧辊管理系统关键技术,改进了轧辊自动配辊功能,指导磨辊间和轧线合理经济的使用轧辊,操作人员可通过调整参数,修改自动配辊的模型,优化选辊方案,使轧辊的使用效益最大化。在分析了轧辊磨损模型基础上,得出轧辊磨损曲线,对轧辊磨损模型进行了进一步的优化,为自动配辊系统提供了理论依据和参数。研究了各机架轧辊的磨损规律,提出模拟计算轧辊磨损量的修正系数,修正轧辊磨损,实际应用结果表明,该模型计算结果更为准确。建立了轧辊管理信息系统,该系统具有全过程动态跟踪轧辊状态、实施合理的轧辊检测和修复、实现高效的精准的轧辊成本管理等功能。通过系统间的数据接口的实现,使原本隔离的数据孤岛连通了。轧辊的信息在各部门各业务系统中实现了共享。系统的平台也支持较为便捷的发布和更新,开发人员在新功能的开发后,各个操作台终端都可以在每次启动程序时,自动更新程序,改变了以往C/S程序更新困难的情况。设计了辊缝校零计算模型,根据L1校正后所得到轧机实际压下位置等数据,结合轧辊的数据、轧机的模量数据、轧辊轴承的种类和带钢的厚度计算所需要的辊缝。所建立的轧辊管理信息系统,提升了轧辊管理专业水平。使连续上机轧制的轧辊比例上升,减少轧辊磨削消耗。降低了轧辊事故发生率,降低了生产成本。
[Abstract]:With China's steel market demand declining in recent years, the steel industry has serious overcapacity, making it increasingly difficult for steel companies to make profits. As a leading iron and steel enterprise in China, we must seize the key moment of industrial structure adjustment and improve management level. The research and development of roll management system can form a unified roll management mode, make the production unit more reasonable and economical to use the roll, give play to the maximum use benefit of the roll, reduce the mm number of roll consumed by tons of steel, and improve the quality of steel production. This paper studies the key technology of the existing roll management system, improves the function of the automatic roll matching, instructs the rational and economical use of the roller between the grinding rolls and the line of the mill, and the operator can adjust the parameters, modify the model of the automatic distribution of the roll, and optimize the selection scheme of the roll. To maximize the use of the roll benefits. Based on the analysis of the roll wear model, the roll wear curve is obtained, and the roll wear model is further optimized, which provides the theoretical basis and parameters for the automatic roll matching system. In this paper, the wear law of roller on each stand is studied, and the correction coefficient of roll wear is put forward. The practical application results show that the model is more accurate. A roll management information system is established. The system has the functions of dynamic tracking of roll status, reasonable roll detection and repair, and effective and accurate roll cost management. Through the implementation of the data interface between the systems, the isolated data island is connected. The information of roller is shared in various business systems of various departments. The platform of the system also supports more convenient release and update. After the development of the new function, the terminal of each console can automatically update the program every time it starts, which changes the difficult situation of updating the C / S program in the past. The model of roll gap zero correction is designed. According to the data of actual reduction position of rolling mill after L1 correction, the data of roll modulus, the type of roller bearing and the thickness of strip steel are used to calculate the roll gap in combination with the data of roll, the modulus of rolling mill, the type of roll bearing and the thickness of strip steel. The established roll management information system improves the professional level of roll management. The ratio of roll rolling is increased and the consumption of roller grinding is reduced. The accident rate of roller is reduced and the production cost is reduced.
