Steel alloy Hot-dip galvanizing American Standard worm for Heavy machinery.
Worm gear is a kind of gear which has one or several spiral teeth and is meshed with worm gear to form staggered shaft gear pair.
Worm gear process:
1.Rough turning, semi finishing turning and finishing turning are the most important process route for common materials.
2.Rough turning semi finishing turning rough grinding fine grinding. For ferrous materials, when the requirements of high precision and small surface roughness value and parts need to be hardened, the subsequent process can only be grinding.
3.Rough turning semi finish turning finish turning diamond turning, for non-ferrous metals, it is not easy to obtain the required surface roughness by grinding, because non-ferrous metals are generally soft and easy to block the gap between sand grains, so the final process mostly uses finish turning and diamond turning.
4.Roughing semi finishing roughing finishing finishing finishing. For the hardened parts of ferrous materials, the requirements of high precision and small surface roughness are often used.
Hot-dip galvanizing is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot-dip galvanizing is to first pickle steel parts. In order to remove iron oxide on the surface of steel parts, after pickling, it is cleaned in a tank with ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride. , And then sent to the hot dip plating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, long service life, etc.
Hot-dip galvanizing is one of the most effective means to delay the environmental corrosion of steel materials. It is to immerse steel products whose surfaces have been cleaned and activated in molten zinc solution. Through the reaction and diffusion between iron and zinc, the steel products The surface is coated with zinc alloy coating with good adhesion. Compared with other metal protection methods, the hot-dip galvanizing process combines the physical barrier of the coating with the electrochemical protection, the bonding strength of the coating and the substrate, the compactness, durability, maintenance-free and economical properties of the coating. It has unparalleled advantages in terms of performance and its adaptability to the shape and size of the product.
