摘要
采用浸泡、电化学、模拟试验以及拉伸试验对冷轧厂电镀锌机组不锈钢紧固螺栓在现行工艺条件下遭受严重腐蚀进行了研究。结果表明，不锈钢紧固螺栓发生严重腐蚀的原因是电镀锌槽中存在着大的杂散电流。因此选用了高强度、耐蚀、不导电的玻璃纤维增强环氧复合材料代替不锈钢来加工制造紧固螺栓。经过现场使用考核，使用寿命有了极大的提高。
The severe corrosion of stainless steel fastening bolts on Electrolytic Galvanizing Line(EGL)in cold strip mill plant under current working conditions has been studied.The results of immersion, elctrochemical and simulatinftests show that the severe corrosion is due to the large stray current on EGL.Andso,the glass fiber reinforced epoxy matrix composite with high strength, corrosiorresistance and inconductivity,is selected to manufacture fastening bolts in place ostainless steel. After the use at site,it proves that the service life is much longerthan that of stainless steel.
