INTRODUCE :
SG iron rolls are available in a variety of hardnesses and compositions for a wide range of applications. These rolls are essentially an infinite chill type material, but with spherical rather than flake graphite, and with higher proportions of nickel, molybdenum and carbon added.
The matrix structure varies from ferrite-pearlite, pearlite to bainite and martensite, with varying carbide contents and spherical/globular graphite.
Applications
1. Roughing stands for bar, wire and section mills;
2. Intermediate stands for bar mills;
3. Sleeves for universal stands.
