[0002] Roller forgings and castings are key components used in the rolling process. Their manufacturing involves two primary technologies: forging and casting. Roller forgings and castings refer to roll components made through forging or casting. Rollers are tools used to roll and shape metal during the rolling process and are widely used in industries such as steel, non-ferrous metals, building materials, rubber, and plastics processing. Forged rolls are formed by forging steel ingots into rolls with specific shapes and properties. Cast rolls are formed by pouring molten metal into a mold and then cooling and solidifying it.
