摘要
铸铝电机转子生产过程采用的电气溶解保温炉 ,其溶铝温度是保证产品质量和工效的关键之一[1 ] 。长期以来只简单采用全通和全断的控制方式控制电热丝加热 ,温度不能精确控制 ,工人劳动强度高 ,更难以满足现代生产的要求。本文就此介绍了采用PLC控制 ,实现电热丝全通、间断导通和全断加热的自适应控制方式的设计和工作原理 ,可将恒温精度控制在± 1℃。
The liquated aluminum's temperature of the electric liquate thermo-insulated furnace used in the machinery manufacture of micro-electrical rotor is the key to ensure the quality of production and working efficiency. The traditional on-off control can't meet the requirement of modern micro-electrical machinery manufacture. This paper presents a new design of PLC control. The control modes used are full on, full off and periodically on-off.The temperature of the furnace can be controlled within 1℃.
