Description

A vertical hot-dip galvanizing device

technical field

The invention relates to the technical field of steel plate hot-dip galvanizing process in the metallurgical industry, in particular to a vertical hot-dip galvanizing device.

Background technique

In modern life, with the continuous development of science and technology, the iron and steel smelting industry is also developing rapidly, so galvanized steel wire is widely used because of its excellent anti-corrosion performance. So far, there are two types of galvanizing processes: electro-galvanizing and hot-dip galvanizing. Galvanizing refers to a surface treatment technology that coats a layer of zinc on the surface of metals, alloys or other materials for aesthetics and anti-rust effects. The main method used is hot-dip galvanizing; zinc is easily soluble in acid and alkali, so it is called amphoteric metal. Zinc hardly changes in dry air. In humid air, a dense basic zinc carbonate film will be formed on the surface of zinc. In the atmosphere containing sulfur dioxide, hydrogen sulfide and marine atmosphere, the corrosion resistance of zinc is poor, especially in the atmosphere of high temperature, high humidity and organic acid, the zinc coating is easily corroded. The standard electrode potential of zinc is -0.76V. For the steel substrate, the zinc coating is an anodic coating. It is mainly used to prevent the corrosion of steel. The quality of its protective performance is closely related to the thickness of the coating. After the zinc coating is passivated, dyed or coated with light protection agent, its protective and decorative plating can be significantly improved. The zinc process is to attach zinc to the surface of the steel wire by electroplating according to the principle of electrochemistry. It has the characteristics of uniform coating structure and excellent plasticity, but the coating is thin. The amount of galvanizing on the surface of electro-galvanized steel wire produced in industrialization is generally less than 30 grams per kilogram of steel wire surface; Because the electro-galvanized coating is thin, its anti-corrosion performance is worse than that of hot-dip galvanized steel wire. In the hot-dip galvanizing process flow chart of the prior art, there are too many steel parts immersed in liquid zinc in the zinc pot equipment (such as the furnace nose, sinking roll, stabilizing roll, bracket and bearing, etc.), and the structure is very complicated, which brings many problems. Disadvantages: (1) Zinc slag is formed between the steel belt and the sinking roller; (2) Causes wear and corrosion of the roller surface and corrosion and wear of the roller shaft and bearing; (3) Zinc slag formed due to component wear; (4) Due to the erosion and wear of liquid zinc, the rotating sinking roller and stabilizing roller need to be replaced frequently (about 15~30 days); (5) The thermal tension device is installed in the high temperature annealing furnace, which makes the operation difficult; (6) The productivity (7) It is unfavorable to the quality of the coating product; (8) There is more liquid zinc. At the same time, electromagnetic sealing technology applies magnetic field and DC current is one of the main ideas of sealing flow, but due to the instability of hydrodynamics caused by large current, sparks may even appear. Under the action of gravity and surface tension, the end of the solution presents a certain curvature. Due to the low current density and the small Lorentz force, the raised solution part cannot overcome the influence of gravity, causing the curvature of the liquid surface to become larger and larger until it drops. It has just caused the current electromagnetic technology to have a leakage problem in the process, that is, the sealing problem of the electromagnetic vertical galvanizing pot. This problem has seriously affected the wide application of electromagnetic vertical hot-dip galvanizing in industry.

The gap between flow components 501 . The fixed plate 403a is provided with a recessed space for accommodating the first electromagnet 403b-1, the wear ring 403e includes a static wear ring 403e-1 and a dynamic wear ring 403e-2 which are fitted together, and the thrust plate 403d is provided with The containing structure for accommodating the second electromagnet 403b-2 and the static wear ring 403e-1, the bottom of the fixed plate 403a and the thrust plate 403c is provided with an elastic connector 403e, and the third sealing assembly 403 is provided in the concave structure of the rotating shaft.

It can be seen that the present invention proposes a vertical hot-dip galvanizing device, one of which is to suspend the conductive liquid (zinc liquid) through the magnetic field generated by the permanent magnet, and use the permanent magnetic sealing technology to realize the sealing of the vertical galvanizing pot, solving the current problem The AC magnetic field sealing and DC magnetic field sealing technology cannot overcome the problems of unstable sealing flow, unstable belt running and material (steel belt) centering; the second is to blow air on the contact surface with the roller part through the provided sealing part, which can solve the problem. The leakage problem exists in the process of electromagnetic vertical hot-dip galvanizing; the third is that through the diversion assembly, the zinc liquid falling from the roller parts can be diverted and recovered to save energy.
