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.
