Abstract

Cast iron containing free graphite has been used as hot rolls in mills since almost fifty years Nodular iron then was recognized as a better material for rolls as it met most of the demands of rolling mills due to the unique combination of high wear & fire crack resistance coupled with good strength and ductilility. The first generation high chromium iron came up in the finising stands of mini mills in the mid 50s. The second generation with 18% chrom-ium was introduced particularly for flat rolling in 70s whilst the third generation with improved heat treatment came up later which is mainly used in the early finishing stands. This paper takes into account all these devel-opments and reports the influence of different roll mate-rial on structure -property correlation in rolled products.
