摘　　要：连续平压法热压机各温度区的控制是实现人造板连续生产得以实施的最重要工艺参数保障措施之一,而热油二次循环系统是设定温度精确控制的最重要手段。基于长期实践经验和探索研究,采用PLC的运算和控制功能,利用PLC的脉宽调制,配置传动机构进行位移调控,从而实现压机各区域温度的精确控制,它有别于传统的热油二次循环系统热压温度控制模式。Accurate temperature control for various zone of continuous hot press is the most important parameter for continuously secure production of wood-based panels. While, thermal oil secondary circulating system is the most important method for controlling accurate temperature setting. Based on long-term practice experience and research, by adopting PLC calculation and control function, the accurate temperature control in various press zones can be realized through PLC＇ s pulse width modulator and transmission mechanism for displacement control. This is different from the traditional thermal oil secondary circulating system.
