1.Description |
|
The high-Cr cast iron rolls are mase by centrifugal casting process, the working layer contains 12-22% |
|
chromium, through rational chemical composition allocations and different heat treatments, the matrix |
|
can be controlled as sorbite, troosite, bainite or martensite and certain kinds of carbides, such as Cr7, |
|
C3 eutectic carbites, Cr23C6 second carbites, Mo2C carbites etc. According to different purpose of use, |
|
the material of the core could be nodular iron or grey iron. |
