About this document
Steel Pickling for Galvanizing Efficiency by Asian Trans Power is a document available to read on EtoBox.
This document discusses the pickling process used to pretreat steel surfaces before galvanizing. Pickling involves using acids like hydrochloric acid or sulfuric acid to remove oxides and mill scales from the steel surface. Hydrochloric acid provides a smoother surface but has pollution and safety issues, while sulfuric acid is safer to handle but produces a rougher surface. The document explores using mixed acids or adding chloride ions to sulfuric acid to get benefits of both. It also discusses defects li
