Forged Steel Rolls and Cast Steel Rolls for Hot & Cold Rolling Mills, Continuous Casting Line, Thick Plate Mills, and Paper Mills
LMM GROUP 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.
WE can provide characteristic service and differentiated products according to the different conditions of rolling mill.The company having the ability to make scientific research, design and develop the rolls with new material and new technology for all kinds of modern rolling mills.
The cemented carbide composite roll is mainly used on the finishing mill for bar, deformed steel bar and common wire. In this way, we can greatly reduce the frequency of changing groove and roll, thus to reduce the labor intensity and improve the work efficiency. The surface quality and yield shall be improved to a maximrurn degree, which leads to a rernarkable ecornmoic benlefit.
ln accordance with the production line and rolling technology of customers, our products are designed to match one-strand rolling, two-slitting rolling and three-slitting rolling. three-slitting rolling, and four slitting rolling, The cemented carbide composite roll includes K1 finished roller, K2 leder roller,K4 pre-slitting roller.K3 slitting roller with high-speed steel as material. The rolling varieties include wire, bar and deformed steel bar.
The company has a raw material analysis center, a rapid analysis center, and a physical test center, which strictly controls the process quality and performance testing of product production, and meets the user’s various quality testing needs for the company’s products. And it provides modern advanced means for the company’s product performance quality control and technology research and development.

LMM high-speed steel rolls have higher steel passing per groove (times) due to their good wear resistance, which saves roll changing time, improves rolling mill operation rate, reduces roll consumption, and improve the overall efficiency of the factory.
Generally, the amount of steel passing in a single groove (times) is 3 to 5 times that of cast iron rolls.
Founded in 2007, LMM GROUP mainly produces all kinds of metallurgical rolls for various types of steel, bar, high-speed wire and strip hot and cold plate and strip rolling mills.
The company covers an area of 100,000 square meters, including two complete production lines for cast rolls and forged steel rolls, processing workshops, product research and development centers, testing centers, training centers and office buildings and other supporting facilities. The factory environment is very beautiful.
