Problems solved by technology

[0002] The roll is an important part consumed in large quantities in steel rolling production. The quality of the roll not only affects the surface quality of the rolled material, but also affects the operating rate of the rolling mill. At this stage, during the use of the roll, the wear resistance is extremely damaged. Therefore, the requirements for its own wear resistance are extremely high. The physical properties of traditional rolls can no longer meet the requirements of production and use. In addition, during the use of rolls, collisions with other objects are also an indispensable link. Therefore, for The hardness requirements of the rolls are also bound to increase

Abstract

The invention discloses a high-hardness and wear-resistant composite roll, which comprises a high-hardness body. The surface of the high-hardness body is inlaid with a plurality of wear-resistant alloy blocks. The wear-resistant alloy blocks include the following components in mass percentage: Si accounts for 24-32%, Zn accounts for 3.6-4.8%, Ni accounts for 2.8-3.6%, Ti accounts for 1.2-2.0%, Mn accounts for 11.2-12.0%, Cr accounts for 11.2-12.0%, and the balance is Fe; The hardness body is formed by high-temperature melting of KmTBCr26 and ZGMn13Cr2. Calculated according to mass percentage, the content of the KmTBCr26 accounts for 52-64%, and the content of the ZGMn13Cr2 accounts for 36-48%. Through the above method, the present invention can have high The characteristics of hardness and high wear resistance greatly increase the service life.

Description

technical field [0001] The invention relates to a roll, in particular to a high-hardness wear-resistant composite roll. Background technique [0002] Rolls are an important component that consumes a lot in steel rolling production. The quality of the rolls not only affects the surface quality of the rolled material, but also affects the operation rate of the rolling mill. Therefore, the requirements for its own wear resistance are extremely high. The physical properties of traditional rolls gradually cannot meet the requirements of production and use, and the collision with other objects is also an indispensable part of the roll during use. The hardness requirements of the rolls are also bound to increase. SUMMARY OF THE INVENTION [0003] The main technical problem solved by the present invention is to provide a high-hardness and wear-resistant composite roll, which can have the characteristics of high hardness and high wear resistance, and greatly increase the service l...
