In order to predict the mechanical properties of the hot rolled strip , the bp algorithm of ann was used to reflect the influence of the chemical composition and the main parameters of hot rolling on the mechanical properties of product and the corresponding software was designed 摘要针对热轧板带的力学性能预报问题，利用人工神经网络中的bp算法建立原始化学成分和热轧生产的主要工艺参数与产品力学性能之间的关系，并开发出专门的应用软件。
Pangan hot strip mill is a large plants for hot steel coil , it ’ s mainline automatic system is two levels , the level 1 is basic automatic control system , and level 2 is process control system , level 2 controls the furnace area 、 rough mill area and finish mill area , it ’ s main function is data traffic 、 steel rolling tracing 、 the model calculating for setup and the sampling for the rolling data . the process system will save a mass of data for model data 、 setup data and sampling data 攀钢热轧板厂是一座大型的热连轧钢板生产工厂,主轧线自动化系统采用2级控制结构,其中第1级是基础自动化控制系统,第2级是过程控制系统,主要完成从加热炉区、粗轧区、精轧卷取区的数据通信、轧件跟踪、加热和轧制模型参数设定计算以及轧制过程参数的采集等主要功能。
After the technique reform in 2003 , the oracle database system replaced the file system , each data for the process system is saved in the oracle database system , and the oracle net 8 is used for the communication between the process servers . how to design a good database system in process system , and how to tune the oracle system become a important problem for pangan hot strip mill after technique reform . this paper introduce the oracle database application system in pangang hot strip mill process system for architecture 、 designing principle and ways 热连轧生产过程是一个快速过程,对过程控制系统的响应时间有很高的要求,通常在100至500毫秒级,过程控制系统本身的计算负荷又很重,由于oracle数据库不是一个实时数据库,如何设计一个适应热连轧过程控制的oracle数据库应用系统,以及如何优化oracle数据库系统,使其稳定高效的运行,保证热轧生产的顺利进行,是攀钢热轧板厂过程控制系统改造后急需解决的一个课题。
This paper researches the distribute monitor and diagnose system ( dmds ) bases on the high - pressure spray descaling system in hot strip rolling factory . it aim to make the technology of status monitor and faults diagnosis adapt to the modern machinery ' s development trend of large scale , scattering and group at the same time realize scattering monitor and centralize diagnosis 为使状态监测与故障诊断技术适应机械设备大型化、分散化、成组化的发展，实现分散监测、集中诊断管理目的，以某大型钢铁(集团)公司热轧板厂除鳞高压水系统为具体对象，进行了分布式监测诊断系统dmds的研究。
The construction of the production management system can solve the interface and support problem between production system and the erp system , and can supply the necessary method for the produce management of the hot strip mill to increase produce management level . in this article , it based on the production management system project of the hot strip mill of pangang and the request of the integrated produce and sale system and the scheme of the system and demand analysis to make the basic design from the system point of view . it defines and describes the composition for the system , and the main contents including : flow structure , system request , system platform design , soft and 生产管理系统建成后,一方面解决生产系统与整体产销系统的接口及支撑问题,一方面为热轧板厂生产管理提供必要的手段,提高生产管理水平本文针对攀钢热轧板厂生产管理系统改造项目,依据攀钢整体产销系统的要求和热轧生产管理系统方案、需求分析等为基础,从系统的角度对攀钢热轧板厂生产管理系统进行基本设计,重点定义并描述生产管理系统相关构成,内容主要涉及到:流程结构、系统要求、系统平台设计、系统软/硬件体系、应用系统架构结构及功能分配、类图定义、数据库定义、主要代码等。
