Additional Details

A "stringing line in cold rolling" is a specialized machine used to apply an organic coating, often referred to as "string compound" or "string lubricant," onto the surface of cold-rolled aluminum coils or sheets. The purpose of the stringing line is to improve the surface quality and enhance the formability of the aluminum material during subsequent processing or use.

Usage of Stringing Line in Cold Rolling:

  • Surface Protection: The organic coating applied by the stringing line acts as a protective layer on the surface of the cold-rolled aluminum, preventing scratches, abrasions, and other surface defects.
  • Lubrication: The string compound acts as a lubricant during further processing, such as slitting or forming, reducing friction and wear on the aluminum material and processing equipment.
  • Formability Improvement: The coating enhances the formability of the aluminum, allowing it to be easily shaped and formed without cracking or tearing.

How Stringing Line Works in Cold Rolling:

  • Material Loading: The cold-rolled aluminum coils or sheets are loaded onto the stringing line.
  • Coating Application: The string compound is uniformly applied onto the surface of the aluminum material as it passes through the stringing line.
  • Drying and Curing: After the coating is applied, the aluminum material goes through a drying and curing process to remove excess moisture and ensure the coating adheres properly to the surface.
  • Winding or Recoiling: Once the coating process is complete, the aluminum coils or sheets may be wound or recoiled for further processing or storage.
