研究了特种消失模铸造生产线的工艺流程及运行特性。针对砂处理生产线流程控制的特殊功能要求,提出了基于故障预警的控制思想和方案,开发了一套自动化程度高、具有故障诊断和预报功能的监控系统。3年多的使用证明,该系统智能高效,可靠性高,使用维护简便,具有推广价值。 The technological process and operation characteristics of the special lost foam casting production line were studied. In view of the special function requirements of the flow control of the sand production line, a control thought and scheme based on the fault pre-warning is proposed and a monitoring system with high degree of automation, fault diagnosis and forecasting function is developed. More than three years of use proved that the system is intelligent and efficient, high reliability, easy to use and maintain, with promotional value.
