Hot Dip Galvanizing Line

Galvanizing is the reaction between molten metal and iron matrix to produce alloy layer, so as to combine the matrix and coating. Hot dip galvanizing is to pickle the iron and steel parts first. In order to remove the iron oxide on the surface of the iron and steel parts, after pickling, it is cleaned in ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank, and then sent to the hot dip galvanizing tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

Description:

In the process of galvanizing production, the noise mainly comes from zinc pot production and fan noise. Because the galvanizing is in a closed workshop, the noise generated by production is less than 85 dB, and there is no need for compartment noise reduction treatment. Other pollution sources come from the pickling process in the hot-dip galvanizing workshop, and a certain amount of acid mist overflows in the production process; A large amount of zinc fume will be produced in the process of hot-dip galvanizing; Waste acid, waste zinc ash and slag produced by long-time pickling; The auxiliary plating solution removes the sludge generated in the iron regeneration process. We designed the project to treat the three wastes generated in the production process. Based on the previous engineering practice, we completed the scheme by using the most advanced environmental protection concept.
