According to the trial situation, The average amount of steel passing through LMMGROUP rolling is about 50%-60% of the alloy rolling spoke. The processing difficulty of high-speed steel is low, and the processing cost is lower than that of the alloy rolling wheel.

Product advantage

The world No. 1 in crude steel production steel plant, over 70% of the HSS for bar and wire are from us.

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.
