These are cast iron based rolls alloyed with Nickel,
Chromium and Molybdenum having a matrix of pearlite
and carbide with flake graphite. These rolls are
used primarily for Section Rolling. The material
has very good thermal properties coupled with property
of imparting good surface finish to the product.
These rolls are also available in higher hardness
range where the matrix is Bainitic instead of Pearlitic
are used in finishing stands of rod mill. |
