625合金冷轧板酸洗工艺研究
|
摘要
采用碱洗-混酸酸洗工艺对2 mm厚625合金冷轧板进行正交酸洗试验。结果表明:625合金冷轧板最佳的酸洗工艺为:首先在500℃~550℃质量分数为80%NaOH+20%NaNO_3的碱液中碱洗60 s~120 s,随后在45℃~50℃质量分数为20%HNO_3+4%HF的混酸溶液中酸洗30 s~60 s,酸洗及精整后板材表面质量达到2B级,各项性能指标与进口板材相当。
The orthogonal pickling tests for 2 mm-thick 625 alloy cold-rolled sheets were conducted by using the alkali washingmixed acid pickling process. The results showed that the best pickling process for 625 alloy cold-rolled sheets is as follows:Firstly,the sheets should be alkali washed in 80% Na OH + 20% NaNO_3( w) for 60 ~ 120 s at 500 ~ 550 ℃ and then pickled 20% HNO_3+ 4% HF for 30 ~ 60 s at 45 ~ 50 ℃. After pickling and finishing,the sheet surfaces of 2 B level could be ganed and performance indexes are equivalent to those of the imported sheets.
