摘要: 利用一維穩態傳熱模型,計算中間包底面溫度,建立了底面溫度與中間包襯里損傷程度間的對應關系,發現中間包底面溫度隨著襯里損傷程度增加而增加.紅外熱像檢測表明:中間包底面溫度隨著包齡的增加而增加;紅外熱像技術可以有效地對中間包襯里損傷進行檢測;利用所建立的理論關系式,可以實現對中間包紅外熱像的定量分析.Abstract: 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.
