摘要
熔融金属/熔渣-氧化物之间的高温润湿行为对于解析其高温界面现象十分重要。该文设计了一系列熔融金属/熔渣-Al_(2)O_(3)/MgO的接触角测量实验,包括样品的制备、实验重现性和稳定接触角的获得,将熔融金属/熔渣-氧化物的高温润湿行为可视化,并分析了其影响因素。结果表明:实验获得的接触角重现性较好,可用于进行熔融金属/熔渣与各类氧化物之间接触角的测量,且熔融金属材质、熔渣成分、温度等均是影响二者之间接触角的重要因素。熔渣-Al_(2)O_(3)/MgO之间的高温润湿性较好,1600℃时的接触角均在15°以下,远小于90°;而熔融铁液-AlO之间不润湿,接触角为130.03°,远大于90°。
The high temperature wetting behavior between molten metal/slag-oxide is key to analyze its high-temperature interface phenomenon. A series of contact angle measurement experiments of molten metal/slag-Al_(2)O_(3)/MgO are designed, which involves sample preparation, experiment reproducibility, and the acquisition of stable contact angle. Meanwhile, the high temperature wetting behavior of molten metal/slag Al_(2)O_(3)/MgO is visualized. It is shown that the contact angle obtained based on this experiment has great reproducibility, which can be used to measure the contact angle between molten metal/slag and various oxides. The molten metal material, slag composition, temperature, etc. are all important factors that affect the contact angle.The high temperature wettability of slag-AlO/MgO is good. And the contact angle at 1600 ℃ is below 15°which far less than 90°. However, there is no wetting between molten iron and AlO, and the contact angle is 130.03°, which is much higher than 90°.
