Steel pipe hot galvanizing device

Abstract

The invention discloses a steel pipe hot galvanizing device which comprises a hot galvanizing box. Opposite rollers are horizontally arranged in the hot galvanizing box. Each roller is rotationally connected with the hot galvanizing box through a power input mechanism. The inner diameters of the two ends of a to-be-galvanized steel pipe are connected with a horizontal movement mechanism through aclamping mechanism, wherein the horizontal movement mechanism is arranged on the outer side of the hot galvanizing box. The clamping mechanism comprises oppositely-arranged vertical plates, and rolling wheels are oppositely arranged on the opposite faces of the vertical plates. Each vertical plate is upwards connected with a height adjusting mechanism. One end of each height adjusting mechanism isconnected with a first nut. The first nuts are rotationally connected to a first lead screw. The first lead screw is arranged to be opposite towards the two ends from the center line. The first leadscrew is connected with the horizontal movement mechanism through a mounting plate. A zinc blowing mechanism is arranged on one side of the hot galvanizing box and is in sliding connection to a zinc blowing movement mechanism. The steel pipe hot galvanizing device has the advantages that uniform hot galvanizing and surface treatment after galvanizing are achieved, and the structure is simple.

Description

technical field [0001] The invention relates to the technical field of galvanizing, in particular to a steel pipe hot-dip galvanizing device. Background technique [0002] Galvanizing refers to the surface treatment technology of coating a layer of zinc on the surface of metal, alloy or other materials to play the role of beauty and anti-rust. The main method is hot-dip galvanizing. It has a history of 170 years since France applied hot-dip galvanizing to industry in 1836. However, the hot-dip galvanizing industry has been developed with the rapid development of cold-rolled strip steel in the past 30 years. Large-scale development, the production process of hot-dip galvanized sheet mainly includes: original sheet preparation → pre-plating treatment → hot-dip galvanizing → post-plating treatment → finished product inspection, etc. [0003] Steel pipes are widely used in modern industrial production and life. They can be used as both supports and connectors. Since steel pipes...

AI Technical Summary

Problems solved by technology

[0003] Steel pipes are widely used in modern industrial production and life. They can be used as both supports and connectors. Since steel pipes are mainly made of steel, they will react with moisture in the air to produce rust when exposed to the outside world for a long time, which will affect the steel pipes for a long time. Therefore, the current steel pipes need to be galvanized for anti-corrosion treatment after the production is completed. Due to the characteristics of the steel pipes, the surface is prone to warts after galvanizing, which affects the surface finish and thus affects the use.
