Adamite Vertical Roling Rolls

Bainitic Nodular Cast Iron Rolls (SGA) Alloy elements of Ni.Mn.Cr.Mo etc., are added to bainitic nodular cast iron rolls for obtaining acicular (bainite-martensite) matrix in its microstructure of these rolls. Its strength and toughnes are higher than Perlitic Nodular Cast Iron Rolls, wearability is also better than latter. These rolls can be produced by static casting and centrifugal casting.
