Embodiment Construction

[0046] The technical solution of the present invention will be further described in detail below in conjunction with specific examples, but the protection scope of the present invention is not limited to the following description.

[0047] A hot-dip galvanizing process for iron tower components, the process comprising:

[0048] S100: Black parts inspection, inspect the galvanized parts that need to be hot-dip galvanized, and those that do not meet the galvanizing conditions are not allowed to enter the galvanizing production line;

[0049] S200: pickling during loading, pickling the plated parts that meet the galvanizing conditions with pickling solution;

[0050] S300: Rinse and dry. Plated parts that have passed the pickling process enter the rinsing process tank and are rinsed with running water to remove the residual acid solution on the surface. The time of staying in the tank is not less than 15 seconds. Soak the tank with plating flux for 0.5-2.0 minutes, and then dry ...

Abstract

The invention relates to a hot-dip galvanizing process and a hot-dip galvanizing solution system for iron tower components. The process includes black parts inspection, material pickling, rinsing and drying, hot-dip galvanizing, cooling passivation, re-plating treatment, and correction According to the galvanizing process, the pickling pool, rinsing pool, drying room, galvanizing boiler, cooling pool, and passivation pool are set up according to the galvanizing process. The conveying rail is laid above it, and the feeding hanger is hung on the conveying rail. The plated parts are transported to each processing area. The galvanized boiler includes a heat insulation layer and a boiler body. The boiler body is erected in the heat insulation layer. The bottom of the boiler body is used as a combustion chamber. Composed of a shaped part and a horizontal part, the arched part is located in the center of the bottom of the pot, and the arched part is surrounded by horizontal parts, and the thickness of the arched part and the horizontal part is uniform and consistent. This scheme improves the galvanizing index by strictly controlling the flow and parameter control of the galvanizing process and using the combination of arched pot bottom and horizontal pot bottom.

Description

technical field [0001] The invention relates to the field of hot-dip galvanizing, in particular to a hot-dip galvanizing process and a hot-dip galvanizing system for iron tower components. Background technique [0002] Hot-dip galvanizing (galvanizing) is also called hot-dip galvanizing and hot-dip galvanizing: it is an effective metal anti-corrosion method, mainly used in metal structure facilities in various industries. It is to immerse the rust-removed steel parts in the molten zinc at about 500 ℃, so that the surface of the steel parts will be attached with a zinc layer, so as to achieve the purpose of anti-corrosion. Hot-dip galvanizing process: finished product pickling-water washing-adding auxiliary plating solution-drying-rack plating-cooling-chemical treatment-cleaning-polishing-hot-dip galvanizing completed. Hot-dip galvanizing is developed from the older hot-dip galvanizing method. Since 1836, when hot-dip galvanizing was applied to industry in France, it has a h...
