The hot test of copper staves was carried out using all-scale staveexperiment system and according to the results, the temperature distribution and heatcharacteristics were studied. The result shows that copper stave possesses outstanding heat transferability, a well-distributed temperature field and low temperature on the hot side. In addition, amodel was established to calculate the cooling water channels' inner face temperature. Thecalculation results indicates that the highest temperature of the inner wall of the channels is 42deg C, and at the same time, the cold side of the stave temperature is 42-43 deg C. That is to say,the temperature in the stave is quite uniform.展开更多

The 3-D temperature distribution insidethe stave including isotherm was obtained based on the experiment data. And the effects of thetemperature of cooling water and the velocity of the water as well as the temperature of the furnaceon the 3-D temperature distribution were obtained. The experimental and calculation results showthat the highest temperature of the hot surface is lower than 90 deg C which is very good for thesolidified slag formation on the hot surface and protecting the stave.展开更多
