Embodiment Construction

[0021] In conjunction with the accompanying drawings and specific embodiments, the process steps, features and advantages of the present invention are described in detail as follows.

[0022] refer to figure 1 Shown is a schematic diagram of the steps of an environmentally friendly steel member hot-dip galvanizing process according to an embodiment of the present invention. The hot-dip galvanizing process includes the following steps:

[0023] S1. Pass the steel component through the shot blasting machine to break and peel off the rust block: since the original surface of the steel component often has large rust spots and scales, first use the shot blasting machine to hit the large rust block with steel shot and stripping, to prepare for the complete derusting of the subsequent road; through shot blasting, the rust block on the surface of the steel member can be completely crushed and about 60% of the rust can be removed; in a preferred embodiment, the shot blasting The power...

Abstract

The invention provides an environment-friendly steel component hot-dip galvanizing process. The environment-friendly steel component hot-dip galvanizing process comprises the steps that rust block crushing and peeling are conducted on a steel component through a shot blasting machine; surface derusting is conducted on the steel component obtained after shot blasting treatment through a steel brushassembly; surface grinding is conducted on the steel component obtained after surface derusting conducted through the steel brush assembly through grinder equipment; and the hot-dip galvanizing process is implemented on the steel component. According to the environment-friendly steel component hot-dip galvanizing process, an original acid pickling derusting process is removed; pretreatment is conducted on the surface of the steel component in a fully-mechanical derusting manner, and then, hot-dip galvanizing is conducted; different derusting processes are arranged according to the derusting degree, so that surface treatment of the steel component meet the hot-dip galvanizing requirement, and the galvanizing quality of the steel component is guaranteed; and the efficiency is high, and thetechnological process is environmentally friendly and free of pollution.

Description

technical field [0001] The invention relates to the technical field of hot-dip galvanizing of steel components, in particular to an environment-friendly hot-dip galvanizing process for steel components. Background technique [0002] Hot-dip galvanizing is one of the most effective means to delay the environmental corrosion of steel materials. It is to immerse the surface-treated steel products in molten zinc liquid, and coat the surface of steel products through the reaction and diffusion between iron and zinc. Zinc alloy coating with good adhesion. Compared with other metal protection methods, the hot-dip galvanizing process has the protection characteristics of the combination of physical barrier and electrochemical protection of the coating, the bonding strength of the coating and the substrate, the compactness, durability, maintenance-free and economical properties of the coating. It has incomparable advantages in terms of flexibility and adaptability to the shape and s...
