Experimental study on heat transfer characteristics of blast furnace copper staves

Much attention has been paid to copper staves because they have excellent performance and longevity. The hot test of copper staveswas carried out using all-scale stave experiment system and accordingto the results, the temperature distribution and heat characteristicswere studied. The result shows that copper stave possesses outstanding heat transfer ability, a well-distributed temperature field and low temperature on the hot side. In addition, a model was established to calculate the cooling water channels' inner face temperature. The calculation results indicates that the highest temperature of the inner wall of the channels is 42℃, and at the same time, the cold side of the stave temperature is 42-43℃. That is to say, the temperature in the stave is quite uniform.
