VALUE
GET YOUR MILL ROLLS PRODUCE A BETTER PRODUCT FOR A LONGER TIME
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.
Cast rolls technical Process:
Modeling → smelting → centrifugal casting → cleaning → preliminary heat treatment → rough machining → differential heat treatment → finishing → packaging and delivery.
Technical excellence in our core competencies – melting, casting, forging, heat treating and machining – allows us to provide a superior product and meet the most demanding requirements of our customers.
The company strictly according to modern enterprise management requirements set up a perfectquality assurance system, and passed the ISO9001:2008 quality management system certification,ISO14001:2004 environmental management system certification, OHSAS18001:1999 occupationalhealth and safety management system certification.

Classification Based on Rolling Temperature
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
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.
