Effects of Refining Temperature on JDN-I Flux's Purifying A00 Aluminum
JDN-I flux is used to purify A00 aluminum alloys under the condition of different refining temperature. From the results some conclusions are drawn that, with temperature is raised, the purifying effects of JDN-I flux becomes worse. The suitable scope of temperature is 690～750℃. And the best temperature is 710℃ or so. Additionally, the conclusion is also drawn that the effects of temperature on melting loss is unclear. At different temperature, melting loss roughly holds below 1%. And the mechanism of Flux's effects is also analysed breafly.
