0. At this point, no zinc hydroxide will precipitate but a portion of the iron, calcium sulfate, and other impurities will form a light precipitate. With a coagulant aid, the mixture is sent to a clarifier where a clear overflow containing the dissolved zinc is obtained. This clear overflow is contacted in a reactor with a circulating stream of previously precipitated sludge containing zinc hydroxide. 0 with sodium hydroxide. The bulk of the zinc precipitates onto the existing crystals in the circulating slurry.
The regeneration and copper recovery system for the primary pickle bath 2. The chemical rinse system 3. The use of hydrogen peroxide plus proprietary additives for the secondary pickle. 1 illustrates the final process. Block A shows the work flow through the new system. 5% hydrogen peroxide in sulfuric acid, the work passes through a chemical rinse step that neutralizes the acid dragout. It also precipitates any copper salts by reduction of cupric (Cu2ϩ) ions to cuprous (Cuϩ) ions, which are insoluble at the pH of the chemical rinse.
Et al. ) The raw steel is fed in automatically. The process can be operated continuously or in batches, depending on the material to be coated. 4). The steel is heated by induction and enters the coating chamber through a window profiled to match the cross-section of the steel. The zinc is melted in an inert atmosphere by an electric furnace and flows into the galvanizing unit. The liquid zinc is held in suspension by an electromagnetic field. The speed of the production line is controlled by computer.
