 Rolling mill rolls material


Description: Before 2010, the rolling mill rolls material of the rolling mill was generally 9Cr2Mo. With the improvement of roll forging materials and the improvement of roll quality requirements, it was gradually replaced by 9Cr3Mo after 2015.

Keyword: Rolling mill rolls material

At present, 9Cr5Mo1V roll blanks have been widely used in the cold rolling industry of steel plates, and are recommended as the material of “work roll”. 9Cr5Mo1V has higher Mn, Mo and Cr contents than 9Cr2Mo and 9Cr3Mo. The increase of the content of the above elements can improve the strength and hardness of the material, increase the wear resistance and hardenability of the material (it has better comprehensive mechanical properties after quenching and tempering) and mechanical properties, which is beneficial to improve the thermal processing performance of the roll And improve the surface hardness and wear resistance after heat treatment.

Therefore, the roll blank using 9Cr5Mo1V has higher tensile strength and compressive strength, and under the same rolling conditions, the deflection deformation of the roll is smaller. With the maturity of 9Cr5Mo1V roll manufacturing process and the reduction of cost, the roll blank material of subsequent rolls will be gradually replaced by 9Cr5Mo1V.

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.
