[0002] Strip steel is actually a thinner, narrower and longer steel plate, usually supplied in coils. Compared with steel plates, it has the advantages of high dimensional accuracy, good surface quality and ease of use. It is widely used in the production of welded steel pipes, cold-bent steel billets, and used to manufacture bicycle frames, rims, clamps, washers, spring leaves, cable armor, saw blades, blades, baling iron sheets, etc. During the processing of strip steel, it is necessary to perform bluing treatment in the molten salt of sodium nitrite and sodium nitrate. After the bluing operation is completed, the temperature of the strip steel is relatively high. In order to ensure the performance indicators of the steel, the strip steel needs to be cooled at this time.
