摘要
设计了一种基于STM32系列单片机为核心的智能钢水测温定氧仪表。仪表的主要功能是在线实时测量钢水的温度与氧电势,并通过内嵌的计算模型得出钢水的氧含量、铝含量与碳含量。现场实验证明:该系统温度测量误差Δt<±1℃,氧电势误差Δe<±1 mV,模型碳与铝含量的计算相对误差<±0.8%。与传统单片机仪表相比,该仪表具有精度高、扩展性强、内嵌模型可调整等优点。
An intelligent molten steel temperature and oxygen content measuring device based on STM32 microprocessor is designed.The function of device is an online temperature measurement,oxygen potential measurement and computation the content of Oxygen and aluminum and carbolic by the embedded computing model.The results of experiment show that the measuring error of temperature ＜ ± 1 ℃ and oxygen content potential ＜ ± 1 mV ;the relative measurement error of aluminum content and carbon content ＜ ± 0.8％.Compared with the traditional microcontroller,this device has higher accuracy,scalability,and adjustable embedded model.
