Forged Steel Rolls for Steel Mills | Rolling Mill Rolls
Forged Steel Rolls and Cast Steel Rolls for Hot & Cold Rolling Mills, Continuous Casting Line, Thick Plate Mills, and Paper Mills
LPR offers forged steel rolls and cast steel rolls to steel mills, steel processing lines and for machine makers that supply to steel rolling mills. Product range includes forged steel work rolls, tension leveling rolls, bridle rolls, furnace rolls, deflector rolls, pinch roll assemblies and roller tables. Our forged steel rolls and cast steel rolls are currently used in world’s largest steel mills, paper and pulp mills, and chemical industries. A wide range of forged steel rolls and cast steel rolls can be custom designed and reverse engineered for the most demanding requirements to have wear resistance, strength against heat and core resistance to increase roll life, and shorten replacement period. In-house engineers of forged steel rolls can also provide material substitution or quality recommendations for new replacement rolls. Our steel roll manufacturing plant is ISO 9001 and ISO 14001 certified.
As a main supplier to POSCO, Hyundai Steel, and JFE Steel, a wide range of forged steel rolls and cast steel rolls have been supplied globally to steel suppliers and major steel industry tier 1s.
Forged Steel Rolls & Cast Steel Rolls | Precision Machined Mill Rolls
Accumulated engineering and manufacturing experience and technical capability as a forged steel roll and cast steel roll manufacturer led us to become a long term supplier to global steel mills, paper mills and chemical mills. Maintaining good relationship and reputation with rolling mill clients and customers in the steel industry with an R&D focused business model is what made our forged steel roll shop to become a competitive global supplier with patented technology on hardfacing rolls that are commercialized and installed in global steel mills in S.Korea, Japan, and USA. Research and development of manufacturing methods, and material application based on actual clients’ needs and requests are how we stay competitive in the forged steel roll and cast roll market.
Our most popular steel roll portfolio includes, forged steel work rolls, backup rolls, leveling rolls, bridle rolls, hearth rolls, table rolls, bridle rolls, hold down rolls, reel spool rolls, paper rolls, corona roll assemblies, calendar rolls for hot rolling mills, plate bending mills, cold rolling mills, and continuous casting mills.

Patented Technologies in Roll Forming
We own patented technologies in the rolls manufacturing industry. In high frequency heat treatment roll (⌀500 – ⌀1,500), wherein cylindrical rolls of S45C JIS (Hs 70 ±2) Carbon Alloy Steel are manufactured by scrolling (bending and rounding) and welding the ends of flat plate are heat treated to provide homogeneous hardness levels across the roll’s body, including the welded bead.
Our noise prevention table roll patent offers noise dampening in table rolls by application of non-woven fabric to the external peripheral surface of the rolls. This helps in noise prevention, delivers cushioning effect, extends roll’s work life, reduces heat and weight deformation and improves efficiency.
