设计了基于数字信号处理器DSP的热连轧自动厚度控制(AGC)实时仿真器,建立了调厚过程压下系统和变形区的动态模型.仿真时,仿真器实时并行地计算带钢和轧机的模型, 计算机控制系统的控制器运行AGC软件,两者通过内存映像网实时交换数据,因此通过虚拟的对象实现了对AGC软件的实时离线调试

在LECO436氧氮分析仪上研究了1600~2813℃温度范围内钢液脱氮动力学。结果表明:温度低时,脱氮受液相边界层传质及界面化学反应混合控制,温度高时,脱氮受液相边界层传质过程控制。在2250℃以下,温度对k1'的影响服从Arrhenius公式。硫对脱氮的阻碍作用随着温度的升高而降低,在温度2250℃以上,硫的表面活性作用消失
