摘    要：介绍了新型蓄热式钢包烘烤装置自动化系统的构成,重点叙述了其控制功能。针对首钢炼钢厂原有自身预热式钢包烘烤器存在燃气消耗量大、废气污染严重、烘烤效率低等问题,新型烘烤装置采用由西门子S7-200控制器及现场仪表组成的控制系统,通过逻辑顺序控制实现烧嘴自动交替加热及加热温度调节功能。系统自投入以来,运行稳定可靠,提高了生产线的自动化水平,达到了节能减排的目的。

Abstract: Constitution of automation system for new regenerative ladle baking device is introduced,and its control functions are described in detail.In original self-preheating ladle baker of Steelmaking Plant of Shougang,there were large gas consumption,serious waste gas pollution,and low baking efficiency etc.problems.Control system of new baking device consists of Siemens S7-200 controller and site instruments.Through logic sequence control,automatic alternation heating of burner and heating temperature regulation function were realized.Since the system was put into operation,running was stable and reliable,automation level of production line was improved,and purposes of energy saving and pollution reducing were achieved.
