LMM GROUP is one of the largest enterprises specializing in the production of high-performance high-speed steel rolls series products in China
Our products have been running on more than 200 production lines and have rich experience
Introduction
High-carbon high-speed steel roll (HSS roll) is the hot-roll material with the shortest appearance, the fastest development, and the widest application prospect. High-speed steel, also known as wind steel or front steel, means that it hardens even when cooled in the air when quenched and is sharp.
It is complex alloy steel with carbide-forming elements such as tungsten, molybdenum, chromium, and vanadium. The total amount of alloy elements reaches about 10%~25%.
The application of high-speed steel rolls is an important part of the development of modern steel rolling production. It is another significant change to the development of the iron and steel industry after microalloying, controlled rolling, and controlled cooling technology.
Scope of HSS Roll Application
Our high-speed steel rolls are widely used in:
Finished frame (high-speed steel roll), front frame (high-speed steel roll), slitting frame (high-speed steel roll), pre-slitting frame (high-speed steel roll).
High-speed wire mill pre-finishing unit. Finishing Mill for Hot-rolled Narrow Strip Mill.
Finishing stands for spring flat steel mill and small section mills such as angle and channel steel.
Advanced Manufacturing Processes and Implementation Standards
Product design → roll billet design → roll billet manufacturing → roll billet acceptance → annealing → rough turning → ultrasonic flaw detection → high temperature quenching → low temperature tempering → ultrasonic flaw detection → finishing → ultrasonic flaw detection → roll body grinding → roll number → inspection → cleaning → packaging→ storage → shipments→ inspection → use and maintenance →exchanged → improvement of design.
It can be seen from the flow chart that roll manufacturing forms a closed-loop system from product design, production manufacturing, use and maintenance, and improvement design, and the quality of roll is constantly improving.

Intermediate roll
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.
