铝合金焊丝熔体测氢与固体测氢对比分析
Analysis on Determination of Hydrogen in Aluminum Melt and in Solid Alloy Wire
摘要
Abstract
The effects of argon refining process parameters on the hydrogen contents in ER4043 aluminum melt and the re-sulting solid alloy wires were investigated.Experimental results show that reducing the argon flow rate during gas refining can significantly reduce the hydrogen content of melt and decrease the number and size of pores on the longtitudinal section of the samples prepared by reduced pressure test.When the argon flow rate was at 8～10 mL/min,the hydrogen content in melt reached the minimum value.Bulk hydrogen of solid ER4043 alloy wires can be obtained accurately by the LECO RHEN602 hydrogen determinator.Similarly,when the flow rate of argon during smelting was controlled at 8～10 mL/min,the bulk hydrogen in solid alloy wire reached the lowest value of 0.17～0.18 mL/100g Al,which could meet the technical re-quirements of low hydrogen aluminum alloy wire production.In addition,under the same argon refining process,the bulk hydrogen content in solid alloy wire was higher than the hydrogen content in melt,and the ratio of the former to the latter was kept between 1.7 and 2.1.关键词
