Abstract
The invention discloses a method for preventing annealing adhesion of cold-rolled sheet steel coils. The method comprises the step of uncoiling the steel band via processes of chemical degreasing, electrolytic degreasing, coating, drying, steel band coiling and annealing. The steel band is uncoiled on an uncoiling machine, and then is introduced into a degreasing cleaning line to clean residues on the surface of the steel band. A silica layer is formed on the surface of the steel band during the degreasing cleaning process; the sheet steel coils are rolled in the steel coils by a coiling machine after the steel band is dried via the drying process; and the steel coils enter an annealing plant for annealing; and finally the mechanical properties of the steel coils fit the requirements of a standard. The components and usage amount of each component in the chemical degreasing solution are as follows: 32-42 g/L of NaOH, 25-35 g/L of Na2CO3 and 8-10 g/L of Na2SiO3; and the components and usage amount of each component in the electrolytic degreasing solution are as follows: 25-35 g/L of NaOH, 15-25 g/L of Na2CO3 and 5-8 g/L of Na2SiO3. The method provided by the invention has reasonable design of the process flow, simple operations, low cost and high production efficiency, and effectively solves the problem of the annealing adhesion. Simultaneously, the annealing steel band has good mechanical properties and good formability.
