Additional Details

To convert large aluminum ingots into thinner aluminum sheets or coils. It is a critical step in the hot rolling process, where the ingots undergo multiple passes through the mill to achieve the desired thickness and improve the material's properties.

Usage of Reversing Breakdown Hot Rolling Mill:

  • Reduction in Thickness: The primary purpose of the reversing breakdown hot rolling mill is to reduce the thickness of the aluminum ingots to a target thickness suitable for subsequent rolling passes.
  • Improved Material Properties: The hot rolling process refines the microstructure of the aluminum, enhancing its mechanical properties and making it more suitable for various applications.

How it Works:

  • Loading: The aluminum ingots, which are usually preheated to reduce their hardness, are loaded into the reversing breakdown hot rolling mill.
  • Hot Rolling: The ingots are passed through the mill's rolling stands, where the rolls exert pressure on the ingots, causing them to deform and reduce in thickness. The mill's rolls are designed to withstand the high pressures and temperatures involved in the hot rolling process.
  • Reversing: The term "reversing" in the mill's name refers to the ability of the mill to roll the aluminum ingots back and forth through the mill several times. This repeated rolling ensures a more uniform thickness reduction and better mechanical properties.
  • Cooling: After each rolling pass, the aluminum undergoes controlled cooling to maintain the desired microstructure.
  • Multiple Passes: The aluminum ingots undergo several rolling passes through the mill, with each pass gradually reducing the thickness until the desired gauge is achieved.
  • Unloading: Once the desired thickness is achieved, the aluminum sheets or coils are unloaded from the mill, ready for further processing or downstream applications.
