high speed steel rolls


Table of Contents

High-carbon high-speed steel roll (referred to as high-speed steel roll) is the hot roll material with the shortest time, the fastest development and the widest application prospect. High-speed steel is also known as wind steel or front steel, which means that it can harden even when cooled in air when quenched, and it is very sharp. It is a complex alloy steel containing carbide-forming elements such as tungsten, molybdenum, chromium, and vanadium. The total amount of alloying elements is about 10% to 25%.


(1) High hardness of carbide
(2) good thermal stability
(3) Good hardenability
(4) Excellent strength and toughness
(5) Good ability to form oxide film
(6) Good thermal crack resistance
(7) good


The application of high-speed steel rolls is an important part of the development of modern steel rolling production. It is another major change to the development of the iron and steel industry after microalloying, controlled rolling and controlled cooling technology. High-speed steel rolls have been widely used in steel rolling production in the fields of plate, section steel, bar and wire rod in Japan, not only for work rolls, but also for backup rolls. The good wear resistance of high-speed steel rolls is inseparable from its characteristics that are significantly different from traditional rolls.

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.
