Optimization method and application of heating furnace operating parametersfor energy and quality control

摘要:

为了提高加热炉的钢坯加热质量并降低能耗，提出一种基于历史加热数据的加热炉运行参数寻优方法。该方法以降低断面温差和燃料单耗为目标，优化加热炉的炉膛压力、炉温等运行参数。基于该方法构建了运行参数优化推荐系统，可以根据业务规则及评价权重进行交互式、动态化分析并呈现推荐结果。该系统在某钢厂加热炉部署后，利用历史数据进行分析验证，同时满足了降低断面温差和燃料单耗的性能需求。

Abstract:

In order to improve the heating quality of steel and reduce the energy consumption, a method is proposed to optimize the furnace operating parameters based on historical heating data. Taking reducing the section temperature difference and fuel consumption as the goal, this method optimizes the furnace pressure, furnace temperature and other operating parameters. Based on this method, an operating parameter optimization recommender system is constructed, which can analyze and present the recommendation results interactively and dynamically according to processing rules and evaluation weights. After the system is deployed in the heating furnace of a steel mill, the historical data are used for analysis and verification, and the performance requirements of reducing section temperature difference and fuel consumption are met.
