去除助鍍劑中鐵鹽的工藝研究
STUDIES CONCERNING PROCESS FOR SEPARATING FERRATE FROM GALVANIZING AID
-
摘要: 鋼管酸洗經(jīng)水冷后,其表面仍粘附有鐵鹽。熱鍍鋅時,粘有鐵鹽的鋼管進入助鍍劑中浸涂,會將鐵鹽帶入助鍍劑中,直接影響鍍層的質(zhì)量及性能,增大鋅耗量。為去除助鍍劑中的鐵鹽,降低鋅耗,采用正交設(shè)計方案,研究并尋找出影響鐵鹽去除的主要因素,確立了較為可行的工藝方法。Abstract: After water-cooling, the pickled steel tube is stuck with some ferrate on its surface. As a result, during hot-dip galvanizing, when the ferrate stuck pipe is put into the galvanizing aid, the agent is spoiled with the ferrate, which directly produces negaive influence on the quality and performance of the coating and increases zinc consumption as well. To clear the ferrate out of the galvanizing aid so as to reduce zinc consumption, the orthogonal design method was used to investigate and determine the main elements responsible for negatively influencing separation of ferrate from the said aid. As a result, a rather practical process for this purpose has been set up.
