采用浸泡方法研究了316L不銹鋼在燒結(jié)煙氣有機(jī)胺脫硫溶液中的腐蝕行為，主要對(duì)pH、溫度、Cl-濃度和SO42-濃度變化引起的影響進(jìn)行了分析。結(jié)果表明，316L不銹鋼在脫硫溶液中存在點(diǎn)蝕行為，隨著溶液pH、溫度、SO42-濃度(60～140 g/L)、Cl-濃度(1～10 g/L)因素的變化，均有不同程度的腐蝕; 但當(dāng)pH<4、溫度>80 ℃、ρ(Cl-)>10 g/L時(shí)，對(duì)316L的腐蝕影響較為明顯。
The effect of the pH, temperature, Cl- concentration and SO42- concentration on the corrosion behavior of 316L stainless steel in the sintering flue gas organic amine desulfurization solution were studied using immersion method. The results showed that 316L stainless steel had pitting corrosion behavior in the desulfurization solution, and as the solution pH, temperature, SO42- concentration (60~140 g/L), and Cl- concentration (1~10 g/L) factors changing, different degrees corrosion occured; when pH<4, temperature>80 ℃, ρ(Cl-)>10 g/L, the effect of corrosion on 316L was more obvious.
