High-speed steel rolls developed by HANI the amount of steel passing in a single groove (times) is 3 to 5 times that of cast iron rolls.

Perfect production process

Cast rolls technical Process:
Modeling → smelting → centrifugal casting → cleaning → preliminary heat treatment → rough machining → differential heat treatment → finishing → packaging and delivery.

Classification Based on Rolling Temperature

  • When the rolling temperature surpasses the recrystallization temperature of the material being rolled, the process is defined as hot rolling, and the rolls utilized in this operation are termed hot rolling rolls. Conversely, if the rolling temperature falls below the recrystallization temperature of the material, the process is known as cold rolling, with the corresponding rolls referred to as cold rolling rolls.

Classification Based on the Shape of Rolled Products

Rolled products are categorized according to their shapes, with corresponding rolls designed for each type. For instance, rolls used for producing hot-rolled strip products are known as hot strip rolls. Similarly, there are various other types, including cold strip rolls, plate steel rolls, section steel rolls, seamless steel tube rolls, and rod and wire rolls, each tailored to the specific shape and requirements of the rolled product.

Classification Based on the Function or Position of Rolling Mills Along the Rolling Line

Rolls are categorized by their roles or positions in the rolling process. Examples include blanking rolls for initial material cutting, roughing rolls for preliminary shaping, intermediate rolls, pre-finishing rolls, and finishing rolls for final surface quality.

Specialized rolls include cross-cut skinning rolls (for surface defect removal), slitting rolls (for strip division), edge rolling rolls (for edge shaping), piercing rolls (for tube production), and straightening rolls (for shape correction).

Classification Based on Roll Position in the Rolling Mill

Rolls are categorized according to their placement within the rolling mill setup. Work rolls are those that come into direct contact with the material being rolled, playing a crucial role in shaping it.
 
Back-up rolls provide support to the rolling mill structure, ensuring stability during the rolling process. In multi-roll mills, the back-up roll that is positioned farthest from the work rolls also bears this name, emphasizing its supportive function.
 
Additionally, intermediate rolls are situated between the work rolls and the back-up rolls in multi-roll mill configurations, facilitating the rolling process by optimizing pressure distribution and enhancing material deformation.

Classification Based on Mill Roll Material

Based on material composition, rolls can be categorized into four primary types: cast steel rolls, cast iron rolls, forged steel rolls, and powder metallurgy rolls. These categories are further subdivided according to the specific material and principal alloying elements used in the working parts of the rolls, ensuring tailored performance for diverse rolling applications.
