Forging rolls to meet the requirements of cold rolling field and manufacturing method |
| abstract |
The present invention generally relates to forging rolls and their manufacture. More specifically, the present invention relates to forging rolls used in the field of cold rolling. The forged roll comprises a steel composition, the microstructure comprises a tempered martensite having a residual austenite ratio of less than 5% by volume, and an open process carbide network having less than 5% process carbides by volume; Forged rolls exhibit hardness between 780 HV and 840 HV and internal compressive stress of -300 MPa to -500 MP. |
