从邯钢三炼钢厂精炼现场应用角度出发,开发了基于PLC的LF精炼炉生产过程监控系统,详述了包括系统配置、数据库开发、数据通信在内的系统构成,介绍了系统的设计流程及主要功能。工艺人员利用该系统对精炼生产过程中的加料、底吹、供电、测温、喂丝、静吹等多个环节的全自动监控功能及历史查询功能,制定合理的工艺模式,并督导现场操作工按照工艺标准进行操作,实现生产现场的精细化控制,使精炼现场的合金、供电成本大幅降低,取得了良好的经济效果。
Based on the field application of the Third Steelmaking Plant in Handan Iron and Steel Co., Ltd., the production process monitoring system of LF refining furnace based on PLC was developed. The system structure including system configuration, database development and data communication was described in detail. The design flow of the system And the main function. Process staff to use the system of refining the production process of feeding, the end of blowing, power supply, temperature measurement, wire feeding, static blowing and other aspects of the automatic monitoring and history of multi-functional query capabilities to develop a reasonable process model and supervise the operation of the site Workers in accordance with the process standard operation, to achieve the fine control of the production site, refining the scene of the alloy, power supply costs significantly reduced, and achieved good economic results.
