Ladle breakout is a risky affair which is always present in steel making. The ladle breakout involves equipment damage and loss of production and sometimes loss of life. The present article describes the method of automatic detection of hotspot on the cold side of a ladle shell with the help of a group of infrared camera and subsequent processing of the infrared images in the LabVIEW platform. The system layout as implemented in the steel plant along with various pitfalls likely to be encountered during operation is discussed. Finally, the result of the trial run in the steel plant is presented. The system is found to be very effective as a preventive maintenance program to stop or minimise the ladle breakout.

钢包突破是一个危险的事情，在炼钢中总是存在。钢包的破裂涉及设备损坏，生产损失，有时甚至是生命损失。本文介绍了借助一组红外热像仪自动检测钢包壳冷侧热点并在LabVIEW平台中对红外图像进行后续处理的方法。讨论了在钢铁厂中实施的系统布局以及在操作过程中可能遇到的各种陷阱。最后，介绍了在钢铁厂试运行的结果。发现该系统作为预防性维护程序非常有效，可以停止或最大程度地减少钢水包爆裂。
