Problems solved by technology

The carbonized layer is metallurgically bonded to the surface of the material substrate through diffusion rather than coating, which avoids the problem of local damage to the coating. However, the temperature during thermal diffusion is high, and preheating treatment is required for the thread steel to reduce Its deformation, the existing direct thermal diffusion of rebar, will lead to deformation

Description

technical field [0001] The invention relates to the technical field of thermal diffusion of threaded steel, in particular to a treatment method and equipment for thermal diffusion of threaded steel. Background technique [0002] Rebar is a common name for hot-rolled ribbed steel bars. In the prior art, rebar is an important part of reinforced concrete structures and one of the necessary building materials for infrastructure. Generally speaking, because the medium environment inside the concrete is alkaline, the corrosion rate of ordinary rebar in an alkaline environment is very low, or even negligible; but if enough chloride ions penetrate into the interior of the concrete and come into contact with the rebar, then Will significantly accelerate the corrosion of rebar. Therefore, in engineering applications, it is necessary to treat the surface of rebar to enhance corrosion resistance. One of the more commonly used is thermal diffusion infrared coating organic coating. [...
