连续铸钢用中间包衬里损伤的红外检测分析

Infrared Detection and analysis on the Lining Damage of a Continuous Casting Tundish

利用一维稳态传热模型,计算中间包底面温度,建立了底面温度与中间包衬里损伤程度间的对应关系,发现中间包底面温度随着衬里损伤程度增加而增加.红外热像检测表明:中间包底面温度随着包龄的增加而增加;红外热像技术可以有效地对中间包衬里损伤进行检测;利用所建立的理论关系式,可以实现对中间包红外热像的定量分析.

The temperature of the bottom surface of a tundish was calculated by using an one-dimensional steady-state heat transfer model. The relationship between the temperature of the bottom surface and the damage degree of the tundish lining was established. It was found that the temperature rises with the increase of damage degree. Practical examinations proved that the temperature of the bottom surface rises with the increase of tundish age, and both the detection of damage degree and the quantitative analysis of tundish lining can be carried out by the infrared image technology.
