Problems solved by technology
[0004] Aiming at the above-mentioned problems existing in the prior art, the technical problem to be solved by the present invention is: the steps such as alkali washing and degreasing, pickling and water washing in the existing hot-dip galvanizing process are not in place and thorough enough; , the zinc solution is difficult to infiltrate and a large amount of resident agglomeration, pipes to be plated workpiece hanger is difficult, galvanizing is not easy; the plating solution on the surface of the workpiece to be plated cannot be evenly covered; There are many tumors, which wastes zinc liquid and increases labor; the sequence of passivation, finishing and polishing steps is unreasonable; therefore, it is necessary to provide an efficient hot-dip galvanizing process to improve the quality of galvanized workpieces and improve the efficiency of hot-dip galvanizing

Embodiment 1
[0033] A high-efficiency hot-dip galvanizing process, the specific steps are as follows:
[0034] 1) Inspection and hanging of workpieces to be plated: inspect the workpieces to be plated, physically remove large dirt, and hang up the inspected workpieces to be plated; especially, for pipeline structures that are difficult to infiltrate corners and easy to reside in zinc liquid For the workpiece to be plated, the way of the hanger is an important factor affecting the galvanizing process. The hanger tool and the way of the hanger for the pipeline class workpiece to be plated in this embodiment are as follows: figure 1 with figure 2 shown in figure 1 Among them, for shorter pipes to be plated, hang them on the hanger with one end facing upward and the other end down; for longer pipes to be plated, hang them obliquely on the hanger , these two hanging methods can effectively make the workpiece fully soaked in the steps of alkali washing, pickling, water washing and galvanizing...

The invention discloses an efficient hot galvanizing process, and belongs to the technical field of hot galvanizing. The efficient hot galvanizing process comprises the steps of to-be-galvanized workpiece inspection and hanging, alkali liquid degreasing, water washing, acid washing, water washing, plating assisting, drying and preheating, hot galvanizing, cooling, inspection, grinding and passivation. According to the galvanized workpieces prepared through the efficient hot galvanizing process, the surface galvanized layer is more uniform in thickness, and the galvanized workpieces can be moretightly combined with steel workpieces; and the surface is smooth, fine and free of wrinkles and clumps, the wear resistance and corrosion resistance are avoided, the loss of zinc liquid is effectively reduced, and the working efficiency of galvanization and the quality of the galvanized workpieces are improved.
Description
technical field [0001] The invention belongs to the technical field of hot-dip galvanizing, and more specifically relates to a high-efficiency hot-dip galvanizing process. Background technique [0002] Hot-dip galvanizing (galvanizing), also known as hot-dip galvanizing and hot-dip galvanizing, is an effective metal anti-corrosion method, mainly used in metal structure facilities in various industries. The hot-dip galvanizing process is widely used on the surface of steel products. It uses the low melting point of metal zinc to adhere to the high melting point steel surface. The hot-dip galvanized layer has good corrosion resistance and is suitable for use in ordinary atmospheric environments. The service life can reach more than 30 years, and the surface of the coating is bright, beautiful, strong in adhesion, and uniform in coating, which is widely used in various fields. [0003] Although there is a traditional hot-dip galvanizing process in the prior art, there are stil...
