Description

Technical Field

[0001] The utility model relates to the field of steel strips, in particular to a temperature control device for blueing treatment of steel strips. Background Art

[0002] The bluing treatment of steel strip is an important surface treatment technology. Through specific process steps, a protective oxide film is formed on the surface of the steel strip, thereby improving the corrosion resistance and decorativeness of the steel strip. The surface of the steel strip after this treatment is hard, shiny, and has a certain aesthetics. The principle of bluing treatment is mainly to use a strong oxidant to oxidize the surface of the steel strip into a dense ferroferric oxide film. This film can effectively protect the inside of the steel strip from oxidation, thereby improving its rust resistance. The temperature control device plays a vital role in the bluing treatment of steel strip. It can monitor and adjust the temperature during the heating process in real time to ensure that the steel strip is always in the optimal temperature range during the bluing process. This can not only ensure the uniformity and density of the blue layer of the steel strip, but also avoid problems such as the degradation of the steel strip performance or the shedding of the blue layer due to excessively high or low temperatures.

[0003] However, general temperature control does not have a cooling device, so that the surface temperature of the steel strip is very high after the bluing treatment, which can easily cause burns to workers and thus cause safety accidents. For this reason, we have proposed a temperature control device for the bluing treatment of steel strips. Utility Model Content
