摘　　要：空分设备低温系统因温差存在冷量损失。阐述了空分设备热交换不完全冷损、跑冷损失、其他形式冷损特点,介绍了马钢20000 m3/h空分设备存在的冷量损失现象,并分析了原因,提出了具体的处理措施及,取得了明显的效果。The low-temperature system of air separating unit has cold loss due to temperature difference. The characteristics of incomplete cold loss, cold escape loss and other types of cold loss in air separating heat exchange are presented. The cold loss phenomenon of the 20000 m3/h air separating unit at Ma Steel is introduced. The causes of the loss were analyzed and specific treatment measures were put forward, which has achieved significant effect.
