A surface galvanizing treatment process for building steel structure pipe fittings

Abstract

The present invention relates to a surface galvanizing treatment process for building steel structure pipe fittings, which mainly includes the following steps: cleaning operation, galvanizing treatment, passivation operation, grinding treatment, inspection and collection and other processes. The steel structure galvanizing equipment used includes Bottom plate, conveying device, galvanizing device and collecting device, the present invention can solve the following difficult problems existing in the galvanizing treatment of existing steel structure pipe fittings. When the steel structure pipe fittings are taken out, when the material is taken out manually, it will be scalded by the zinc liquid accidentally, and the galvanized steel structure pipe fittings cannot be cooled in time, so that there are more zinc tumors on the steel structure pipe fittings, which affects the steel structure. The quality of galvanizing of pipe fittings; b, the existing galvanizing furnace is unreasonable due to the unreasonable setting of the burner, which causes the heat inside the furnace body to fail to circulate, which can improve the efficiency and quality of galvanizing steel structure pipe fittings.

Description

technical field [0001] The invention relates to the technical field of steel structure galvanizing, in particular to a surface galvanizing treatment process for building steel structure pipe fittings. 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 rust prevention. Zinc is easily soluble in acid and alkali, so it is called amphoteric metal, zinc There is almost no change 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 In an atmosphere with high temperature and high humidity containing organic acids, the zinc coating is easily corroded. After the zinc coating is passivated, dyed or coated with a light-protecting agent, its protection and decorat...

AI Technical Summary

Problems solved by technology

[0003] However, the following problems exist in the galvanizing treatment of existing steel structure pipe fittings. a. When galvanizing traditional steel structure pipe fittings, it is necessary to manually use clamping tools to take out the galvanized steel structure pipe fittings. It will be scalded by zinc liquid, and the galvanized steel structure pipe fittings cannot be cooled in time, so that there are more zinc nodules on the steel structure pipe fittings, which affects the quality of galvanized steel structure pipe fittings; b, the existing galvanizing furnace Due to the unreasonable setting of the burner, the heat inside the furnace body cannot circulate, which not only increases the waste of energy, but also reduces the quality of galvanizing products, which can improve the efficiency and quality of galvanizing steel structure pipe fittings
