介绍了酒钢中板加热炉控制系统的组成。在炉内传热数学模型的基础上 ,建立了加热炉在线优化控制 ,实现了炉温优化控制。根据现场的能源测试与统计 ,与同类型没有实现优化控制的加热炉相比 ,板坯的加热质量有明显改善 ,燃耗和氧化烧损降低了约 5 %和 6 % ,取得了明显的经济效益。

Control System for Slab Re-heating Furnaces of JISCO CHEN You-wen (Jiuquan Iron and Steel Company,Jiuquan 735000,China)The components of control system for slab re-heating furnaces were introduced, and on-line optimum control system was established on the basis of math model of furnace conduction, the optimum control of furnace temperature was achieved. According to the power test and statistics in-situ, the heating quality of slab improved greatly compared with the re-heating furnace with no optimum control system, and the consumption of fuel decreased 5%, loss of oxide decreased 6% and great economy effects were achieved.re-heating furnace;math model;optimum control
