Embodiment Construction

[0012] A spraying method for steel structure materials. The steel components are placed on a closed conveying device, firstly conveyed to the dust removal device to remove dust and burrs on the surface of the steel structure materials, and then the cleaned steel structure materials are conveyed to the hot air channel for pretreatment. Heat treatment, the temperature of preheat treatment is set at 80-150°C. After the preheat treatment is completed, the steel structure material enters the spraying room for rotary spraying treatment with a spray gun. After spraying, it enters the curing dryer to heat and cure the coating. The temperature is 200-250°C.

[0013] Among them, after the steel structure material enters the dust removal device, while moving on the conveying device, the brush set above the steel structure cleans the burrs on the surface of the steel structure material, and at the same time, the suction fan absorbs the dust on the surface of the steel structure; the steel ...

Abstract

The invention discloses a spraying method for a steel-structure material. According to the method, a steel-structure component is arranged on a sealed conveying device; firstly the steel-structure component is conveyed to a dedusting device to remove dust and burs on the surface of the steel-structure material; then the cleaned steel-structure material is conveyed into a hot air passage to be subjected to preheating treatment; the temperature for the preheating treatment is 80-150 DEG C; the steel-structure material subjected to the preheating treatment enters a spraying chamber and is subjected to spin-spraying treatment by using a spraying gun; the steel-structure material enters a curing and drying machine after spraying, so that a coating is heated and cured, and the curing temperature is 200-250 DEG C. According to the spraying method, firstly, the surface of the steel material is cleaned, deburred and dedusted, so that the flatness of the spraying surface of the steel material is ensured, and the sprayed surface of the steel-structure material is uniform and high in quality; the preheating treatment is performed before spraying, so that the temperature before spraying is improved, and the spraying uniformity is further improved; and a spinning and reciprocating spraying mode is adopted, so that the completeness and uniformity of spraying are ensured.

Description

technical field [0001] The invention relates to the field of processing steel structure materials, in particular to a spraying method for steel structure materials. Background technique [0002] The good mechanical properties and low manufacturing cost of steel make it play a pivotal role in the production of the national economy. As a structural material, it supports the country's economic construction, and as a tool material, it is used in all aspects of people's daily life. However, Fe, the basic composition of steel, has high electrochemical activity, and it is easy to combine with oxygen in the air to form Fe2O3 oxides to oxidize and corrode. In the environment where water vapor exists, its oxidation and corrosion speed will be accelerated. Under high temperature conditions, Fe and oxygen become more active, and the oxidation and corrosion rate of steel is faster than that under low temperature conditions. In order to solve this problem, the existing method is to spray...
