摘    要：介绍自主研发的转炉过程控制系统功能与模型。针对转炉静、动态模型不同的应用环境,设计开发了以冶金机理为内核的静态模型和以副枪检测值为基础的动态模型,模型的关键参数采用统计学习的方法进行修正。其中静态模型中的氧耗计算、加料计算、装料计算、出钢合金计算以及二次补吹计算等,经过现场测试可以满足工艺要求;动态模型正在进一步测试中。系统框架采用最新的.NET/WCF技术开发,以组件化方式设计,确保系统具有良好的扩展性和稳定性。

Abstract: The functions and the models of a process control system for BOF are introduced in this paper.Dedicated to their different application scenarios,the static and dynamic control models are developed accordingly on different principles.The static model is developed on the basis of mechanism of steelmaking process,while the dynamic model is established on the measurements of sublance.Primary parameters of the models are updated via statistical learning.Verifications of the static model are made on essential calculations that the model performs,including total oxygen volume,scraps weight,additions weight,alloys addition weight and second blow setting.The results of the verifications,in which the calculated values are compared against practical data,indicate that the model satisfies the requirements of production.Further tests on the dynamic model are currently under way.The control system is developed with.NET/WCF framework,and the component based design provides the system with better expansibility and stability.
