A heating and curing furnace for anti-corrosion treatment of steel components

Abstract

The invention discloses a heating curing furnace for anti-corrosion treatment of a steel member surface. The heating curing furnace comprises a fixed heating outer furnace and a movable heating inner tank, wherein the fixed heating outer furnace includes a fixed heating outer sleeve pipe; a fixed heating end wall is disposed on one end of the fixed heating outer sleeve pipe, and an inlet / outlet of the heating inner tank is formed in the other end of the fixed heating outer sleeve pipe; the movable heating inner tank includes a movable heated inner sleeve pipe; a movable closed insulation cover is disposed on one end of the movable heated inner sleeve pipe; a movable support base is disposed at the bottom of the movable heating inner tank; an upper end of the movable support base is located in the fixed heating outer sleeve pipe and is connected with the bottom of the movable heating inner tank; a lower end of the movable support base is located below the outside of the fixed heating outer sleeve pipe; and a base movable hollow groove for enabling the movable support base to pass through is disposed in the bottom of the fixed heating outer sleeve pipe. The heating curing furnace is suitable for heating curing of a surface anti-corrosion treatment layer on a large-size steel member and is high in thermal insulation properties, that is, high in energy-saving level.

Description

technical field [0001] The invention relates to the technical field of steel component surface anticorrosion treatment equipment, in particular to a heating and curing furnace for steel component surface anticorrosion treatment. Background technique [0002] Every year, the world's steel corrosion loss accounts for more than 10% of the total steel output, and the economic loss caused by corrosion in industrially developed countries accounts for more than 2% to 4% of the total output value of the national economy; research and develop advanced anti-corrosion technology to reduce economic losses caused by corrosion Prolonging the service life of steel and other metal materials and equipment is of great significance to promoting the development of advanced technology, cutting-edge science and defense industry, as well as the sustainable and coordinated development of the national economy and social environment.

AI Technical Summary

Problems solved by technology

The embedded parts of bridges with reinforced concrete structure are prone to corrosion and damage the concrete structure of the bridge due to long-term exposure to various corrosion-causing factors such as freezing damage, chemical corrosion, steel corrosion, and alkali-aggregate reaction; especially due to humidity The effect of carbon dioxide, temperature and carbon dioxide will cause carbonization of concrete, and the effect of corrosive media such as oxygen, sulfur dioxide and chlorine will further aggravate the corrosion of bridge embedded parts and the damage of concrete structure

Traditional anti-corrosion processes such as electro-galvanizing, electro-cadmium electro-plating, hot-dip galvanizing, hot-spraying zinc, and phosphating not only have thin anti-corrosion coatings, poor compactness and poor impermeability, but also cause serious pollution to the environment by waste water, waste gas, and waste residues associated with traditional anti-corrosion processes.
