Embodiment 1

[0037] Process preparation: several pickling pools, rinsing pools, fluxing pools, galvanizing pools, cooling pools, passivation pools, unloading areas, and pickling pools are set up in sequence from left to right inside a closed steel structure. Both the material side and the discharge side are equipped with double doors; loading: put the workpiece to be galvanized on the material trolley, use the power switch to control the material trolley to walk along the predetermined track in a straight line, when the material trolley enters the closed steel structure, turn off the pickling The first lifting door on the feed side of the pool, at this time, start the switch to open the second lifting door, so that the material trolley can approach the pickling pool; pickling: when the workpiece to be galvanized is transported to the vicinity of the pickling pool, start The first crane lifts the workpieces to be galvanized into each pickling pool from right to left in turn, and starts pickl...

Embodiment 2

[0039] In embodiment one, add following operation:

[0040] In step 1, a transparent glass fiber reinforced plastic anti-corrosion plate is installed on the surface of the airtight steel structure, and a monitoring camera is installed inside the airtight steel structure to monitor the internal operation and ensure the quality of the galvanized workpiece.

[0041] Process preparation: several pickling pools, rinsing pools, fluxing pools, galvanizing pools, cooling pools, passivation pools, unloading areas, and pickling pools are set up in sequence from left to right inside a closed steel structure. Both the material side and the discharge side are equipped with double doors; loading: put the workpiece to be galvanized on the material trolley, use the power switch to control the material trolley to walk along the predetermined track in a straight line, when the material trolley enters the closed steel structure, turn off the pickling The first lifting door on the feed side of the ...

Embodiment 3

[0043] In embodiment two, add following operation:

[0044] In step 2, the first lift door on the feed side of the pickling tank is closed from top to bottom, the second lift door on the feed side of the pickling tank is opened from top to bottom, and the first lift door on the feed side of the pickling tank is opened from top to bottom. Both the heavy lift door and the second lift door are airtight doors, which help to ensure the tightness of the structure and reduce the leakage of acid gas.

[0045] Process preparation: several pickling pools, rinsing pools, fluxing pools, galvanizing pools, cooling pools, passivation pools, unloading areas, and pickling pools are set up in sequence from left to right inside a closed steel structure. Both the material side and the discharge side are equipped with double doors; loading: put the workpiece to be galvanized on the material trolley, use the power switch to control the material trolley to walk along the predetermined track in a st...

Abstract

The invention discloses an environment-friendly sealed hot galvanizing method, comprising the following steps: process preparation: providing multiple acid washing tools, rinsing pools, plating assistant agent pools, galvanizing pools, cooling pools, passivation pools and an unloading area in a closed steel structure in sequence from left to right; and providing dual doors on feed sides and discharge sides of the acid washing pools. The environment-friendly sealed hot galvanizing method improves the production efficiency of galvanized workpieces, improves the workpiece galvanizing quality, relieves the labor intensity of operators, achieves excellent tightness, prevents workers from directly contacting the working environment of strong acid mist, eliminates the injury of human bodies by harmful chemical gas such as acid gas and smoke, can convert the harmful chemical gas generated by hot galvanizing for qualified emission, improves the enterprise competitiveness, and solves the problems of pollution of ecological environment and body injury of operators by the acid gas and the smoke generated in the hot galvanizing process of metal products.

Description

technical field [0001] The invention relates to the technical field of hot-dip galvanizing anticorrosion technology for metal materials, in particular to an environment-friendly sealed hot-dip galvanizing method. Background technique [0002] Hot-dip galvanizing is also called hot-dip galvanizing and hot-dip galvanizing. It is to immerse the rust-removed steel parts in a molten zinc solution at about 500 ° C, so that the surface of the steel components is attached with a zinc layer, so as to achieve the purpose of anti-corrosion. [0003] In the metal products industry, metal corrosion is ubiquitous. Usually metal products are surface-corroded by hot-dip galvanizing. Hot-dip galvanizing is one of the most effective means to delay the environmental corrosion of steel and metal materials. However, metal products are produced during the hot-dip galvanizing process. The acid gas, dust, etc. pollute the ecological environment, and also cause human injury to the operators. Therefo...
