Additional Details

"Furnaces for hot rolling," also known as "reheating furnaces," are specialized industrial furnaces used in the hot rolling process of metals, particularly steel and aluminum. Hot rolling is a metalworking process where ingots, billets, or slabs are heated to high temperatures and then passed through a series of rollers to reduce their thickness and shape them into desired products like sheets, plates, and structural sections.

Usage of Furnaces for Hot Rolling:

  • Preheating for Hot Rolling: The primary purpose of reheating furnaces is to heat the metal feedstock to the required temperature for hot rolling.
  • Plasticity Enhancement: Heating the metal above its recrystallization temperature increases its plasticity, making it easier to deform and shape during hot rolling.
  • Temperature Uniformity: Reheating furnaces ensure uniform and controlled heating of the metal to achieve consistent hot rolling results.

How it Works:

  • Loading: The metal feedstock, such as ingots, billets, or slabs, is loaded into the reheating furnace.
  • Heating: The reheating furnace uses a heat source, such as burners or electrical heating elements, to raise the temperature of the metal to the desired rolling temperature.
  • Soaking Time: The metal remains in the furnace for a specific duration to ensure that it reaches a uniform temperature throughout.
  • Discharge: Once the metal reaches the required rolling temperature, it is discharged from the reheating furnace and transferred to the hot rolling mill.
  • Hot Rolling: The heated metal is passed through a series of rolling stands, where it undergoes plastic deformation to reduce its thickness and achieve the desired shape.
  • Cooling: After hot rolling, the processed metal may go through controlled cooling processes to adjust its properties or achieve specific mechanical characteristics.
