We have found GPIL to be an excellent choice for steels where chipping and cracking have not been a problem. It has worked well in applications on thinner ...
These centrifugally cast rolls have a high Chromium content shell with a nodular iron core like a conventional Hi-Cr Iron roll but the Carbon content & Cr to C ratio are precisely controlled to get a balanced microstructure in between a conventional Hi-Cr (I) & Hi-Cr Steel rolls.
Chemical CompositionProximate Chemical Composition [ in %- wt ]
Higher Resistant to Oxidative wear as well as Abrasive wear
Higher Resistance to 'Banding" hence better surface quality
Improve gripping thereby reducing roll bite related problems
Improved Resistance fire cracking resulting lesser stock removal per campaign
Higher campaign life and lesser grinding due to improved peeling resistance

Composite Anti Peeling Hi-Cr Iron Work Rolls are generally used for the early stands of Hot Strip Mills. Anti Peeling High Chromium Iron rolls are used in the initial stands (F1 to F3 and at times F4) of Hot Strip Mills where the stock undergoes the maximum reduction replacing conventional Hi-Cr Iron rolls
