板坯库实时生产物流管理系统的研发
摘要
在钢铁企业炼钢-连铸-热轧一体化生产模式下,板坯库作为连铸、热轧生产工序间的缓冲环节,其管理自动化水平的高低,直接影响着连铸-热轧生产的连续性和一体化生产的成本。在以往的研究中,人们主要集中在炼钢、连铸和热轧的计划与调度中,忽视了对板坯库管理与控制的研究。因此,本文根据重钢热轧厂1780mm热连轧生产线的实际情况,对板坯库实时生产物流管理系统进行研究,采用Justep Business业务架构平台和Oracle数据库,以Delphi为开发语言,设计并开发满足重钢热轧厂生产需要的板坯库实时管理系统软件。
本文的主要工作如下:
①分析了板坯入库选择垛位的原则,对影响板坯库作业效率的主要因素进行了归纳,以板坯库有限储位和垛位选择原则为约束,建立了一种基于铸轧作业计划协同优化的板坯入库决策模型,实现需入库的板坯批次的全局优化运算,算法可快速优化出板坯入库垛位和铸机板坯产出序。为了克服遗传算法和模拟退火算法在实际应用中显现的不足,构造了遗传模拟退火算法,该算法充分发挥了遗传算法良好的全局搜索能力和模拟退火算法有效避免陷入局部极小的优点,从而提高了算法的全局寻优能力。基于遗传模拟退火算法实现了板坯入库优化程序,并进行了大量的计算。
②详细分析板坯库实时管理系统的需求、热轧和炼钢的物流和信息流,完成了板坯库实时管理系统总体设计和系统实现。
③基于Justep Business业务架构平台和Oracle数据库在MES系统中实现所提出的板坯库管理系统。该生产管理系统对热连轧产线的物料库存、技术质量、生产计划、设备、数据采集等进行管理,实现物流和信息流的协调统一。
重钢热轧厂板坯库实时管理系统软件开发采用软件工程设计方法,依次经过需求分析、详细设计、软件编程、和软件测试等步骤,应用图形界面友好,较好地实现设计目标,得到重钢现场专家们的肯定。
Under the incorporate product model of steel-making, casting, hot-rolling in steel enterprise, slab-yard is used to amortise the product line between the casting and hot-rolling, and the continuity and cost of slab operating is directly effected by the automatic level of its management。In previous Research, people concentrated in continuous casting and hot rolling of the planning and scheduling, ignored the storage management system Research and control.Based the demand of information constructing of Chongqing Iron and Stee Company Limited(CISC),the paper researched the designing and actualizing of the steel company 1780mm hot strip rolling manufacturing management system.It especially researched the slab-yard management.Based on the Justep Business platform and Oracle database,delphi as the development of language,the storage management system in MES was developed.
The contribution aspects can be embodied:
①The rules of slab location and pile position selection are analyzed. According to the factors we induce that affect the efficiency, based on the collaborative optimization of CC-HR operating plan, a slab location decision model which is subject to the limited HCR slab-yard storage and the rules of slab location and pile position selection is suggested. The model is a general optimal operation to a slab lot of entering slab-yard and can quickly optimize the pile position for each slab and the casting sequence. The advantages and disadvantages of genetic algorithms and simulated annealing algorithm are analyzed, and a genetic simulated annealing algorithmx is applied to solve the model. In the algorithm, it makes full use of the excellent whole searching ability of genetic algorithm, and the advantage that simulated annealing algorithm can efficiently avoid getting into part minimum, thus the global searching ability of is improved. The slab location optimization program based on GSA is realized and calculated many times.
②Analysed the demand for the storage management system and the production logistics management information system of the Third Steel-Making Mill and the Second Hot Strip Mill rolling of CISC the storage management system has been designed and realized.
③Based on the Justep Business platform and Oracle database,the storage management system in MES was developed.The material storage,technical quality, manufacturing plan,equipment,data gathering in the company were took charge by the manufacturing management system.It made the material flow and the information flow harmonious.
The method of software engineering was adopted in system development, and requirement analysis, system design, detail design, programming and testing were applied to the system. finally, the storage management system was developed in the slab continuous casting direct hot charge rolling (CC-DHCR) integrated management system for CISC. The software run online now, and it work stability and reliability, have friendly graphic user interface, and reach the target of the project. Steel-Making Experts are very satisfied with this system in CISC.
