Each set of S-rollers in the galvanizing line system uses a control method (tension type or speed type) that precisely matches the function. In the links where precise tension control is required before and after galvanizing, the S-rollers use tension-type control. The system uses a weighing sensor to measure the tension applied to the strip, and the control system adjusts the position or pressure of the rollers accordingly to maintain the required tension. In the section where the strip needs to be conveyed at a constant speed, some conveying links use speed-type control. The motors that drive these S-rollers are precisely adjusted to rotate at a set speed to ensure that the strip moves continuously and efficiently in the continuous galvanizing line.
The hot dip galvanizing line uses a hot-dip galvanizing process to efficiently coat the steel with a layer of zinc, improving its corrosion resistance and durability. In actual production processes, the continuous galvanizing line process varies. Pretreatment equipment is used to remove dirt and impurities from the surface of the steel to ensure that the galvanized layer can be firmly attached to the surface of the steel.
