Background
The deformed steel bar is commonly known as hot rolled ribbed steel bar, and in the prior art, the deformed steel bar is an important component of a reinforced concrete structure and is one of necessary building materials of infrastructure. Generally, as the medium environment inside concrete is alkaline, the corrosion rate of common deformed steel bars in the alkaline environment is very low and even can be ignored; however, if sufficient chloride ions penetrate into the concrete and come into contact with the deformed steel bar, corrosion of the deformed steel bar is significantly accelerated. Therefore, the surface of the deformed steel bar needs to be treated in engineering application to enhance the corrosion resistance. Among them, thermal diffusion infrared coating organic coatings are more commonly used.
The diffusion of chloride ions can be effectively delayed by utilizing the shielding effect of the coating on corrosive media. However, in the coating, installation and service processes of the deformed steel bar, local damage of the coating cannot be avoided, and the thermal diffusion means that the deformed steel bar is soaked in a salt bath for 1-8 hours at a certain temperature under a molten state, the carbonized components dispersed in the salt bath are combined with carbon atoms contained in the material matrix, and a layer of carbonized layer with a compact structure and without pores is formed on the surface of the material matrix through diffusion of carbon and nitrogen. This carbonization zone bonds on the material base member surface through diffusion rather than coating metallurgy, has avoided appearing the problem of the local destruction of coating, but, the temperature is higher during the thermal diffusion, need just carry out preheating treatment to the screw thread to reduce its deformation, current direct carries out the thermal diffusion to the screw-thread steel, can lead to warping.
Based on the method, the invention designs a deformed steel bar thermal diffusion treatment method and treatment equipment.
