【摘要】 钢铁冶炼过程中,高炉炉顶的炉料分布是影响炉内煤气流分布﹑矿石还原﹑炉料—气体热交换﹑燃料比和高炉寿命的重要因素。为优化高炉操作,实现准确控制炉料分布,需要分析高炉布料过程中影响炉料分布的物理现象,寻找装料条件和炉料分布之间的规律。为了直观、形象地反应炉料的分布状况,预测炉况的变化趋势,使用虚拟现实技术来研究炉料在炉内的分布成为一种可能。本文根据高炉炉内炉料分布规律,结合无料钟高炉布料经验,把一次完整的布料过程作为仿真对象。在对其进行数学建模的基础上,运用OpenGL图形库技术,通过对生产工况、场景进行模拟和再现,实时、动态地模拟高炉布料过程。本文实现的虚拟现实环境具有场景漫游功能,并且可以实时与高炉布料装置交互,控制布料装置的仰角、高度和旋转速度,此外还能实时跟踪炉料运动轨迹。该仿真模型为高炉操作者了解、分析和控制炉料在炉内的分布提供了一定依据,另外为高炉设计者和研究人员提供了一种有效、可行的设计和分析手段,为高炉布料模型的进一步发展也提供了一个框架和平台。更多还原

【Abstract】 In iron and steel making processes, burden distribution of blast furnace top is the main factors which influence the gas flow distribution, ore reduction, heat exchange between burden and gas flow, fuel rate and blast furnace campaign life. In order to optimize the operation of blast furnace and control burden distribution precisely, the physical phenomena which influence the burden distribution in the process of burden charging should be analysed, and the relation between charging condition and burden distribution should be searched. Applying the virtual reality technology to simulating the process of burden charging can display the burden distribution states directly and visually, and this could be a better way to estimate the trend of the states of burden distribution.According to the burden distribution rules of the blast furnace and combining the burden distribution experience of the bell-less blast furnace, this paper simulates a whole process of burden charging and realizes visual simulation of the process of burden charging based on mathematics model, using OpenGL library technique, through simulation and reappearance of production and scene.The user can not only navigate in the virtual reality environment, but also be able to interact with the charge distributor of the blast furnace through controlling the angle, height of elevation and angular velocity. Further more, the system can also track the movement path of the charging in real time. This simulation model provides a specific basis to analyse and control the states of the charging contribution for the operator. It can also help the designers who design the blast furnace to evaluate and analyse feasibility of the designs. Moreover, it provides a foundation for the deep development of charging model.更多还原
