Question:

how do I build a steel galvanizing plant. Hot dipped Galvanization?

I would like to build steel galvanization plant.

Answer:

How big of a kettle do you want to go with? A small 6-10 foot kettle would work fine for spinner work (small parts ran in baskets) but if you want to handle large beams and so forth you will need to have at least a 25 foot or longer kettle. You will need tanks for caustic,acid,rinsing,and preflux solutions. If you go with sulfuric acid it will have to be heated. The caustic and flux tanks need to be heated in any case.You will also need a bag house to control smoke coming off the kettle. First you should look into permits such to see if you can actually build this plant. Galvanizing is nasty work and the laws and regs are strict. Former Kettleman
bcaz of the very corrosive conditions in petrochemical plants, steel without coating doesnt work. coating with zinc (e. g. hot dip galvanizing) help protecting the steel for more time, in simple words , zinc is corroded instead of iron and until there is some zinc on the surface steel is protected. we usualy dont use paint coating bcaz: 1.any porosity in the paint coat result in severe corrosion and steel should be completely coated with paint to be protected ,instead large prosity in zinc coating doesnt matter at all 2. usual painting materials arent proper for the severe corrosive condition ASTM standard( american society for testing and materials) offer world accepted standards for painting quality control

That's depending on what type of metal you want to cover the steel parts in the galvanization process. The galvanization in words refers only to that kind of process which is using electric deposition of a metal through a bath of a electrolyte from a plate containing pure metal needing to be deposed on steel tide at the anode electrode or + polarity and at the other side (other electrode, cathode or - polarity). There needs to be a certain recipe of mixed salts for creating very tight and uniform growth crystals, for not being corroded or leafed away with time. There are certain salts which provide this king of growing in the same time with the polished look of the piece galvanized. This salts can be dissolved in water, for creating the electrolyte or being melt (which is not so safe technique) and used and kept like that. The dipping is no so used any more and it can not be called galvanization. More recent techniques use hot plasma blowers, meaning a torch with plasma and a wire of the specific metal to be deposited being melt in the plasma and blown to the surface of the steel part. Anything you'll do you have to deal with the local Environmental Agencies and with the tap water supply/ sewerage administrator, because you;ll have to make a contract with them for you to show that you retain the hard metals from the water dropped to sewerage, if any.
