Pearlitic Rolls

Applications    Mechanical Properties    Chemical Analyses    Hardness    Micrographics

 

Pearlitic rolls are nodular graphite chilled rolls with Pearlitic matrix. The softest grades have a pearlitic matrix with bull’s eyes ferrite, while the hardest grades have a bainitic-pearlitic matrix.

 

To achieve a lower hardness drop in the shell, rolls can be alloyed with chromium. Rolls of this type are suitable for rolls with deep grooves for rolling heavy sections.

 

Pearlitic rolls have good fire crack resistance especially in the softer grades and are suitable for hot rolling in roughing and intermediate stands. Pearlitic rolls are rarely double poured but can be in order to meet the requirements of a specific application.
