Leadar Roll provides high quality cast nodular iron rolls, which are a high quality economical choice in today’s rolling mills. Iron, or nodular Iron, is a generic description of a common industry grade of cast ductile iron or spheroidal graphite cast iron. Nodular Iron materials have a toughness advantage over grain or chill iron grades.
Bainitic Nodular Cast Iron Roll. Bainitic nodular cast iron roll is made of Ni, Mn, CrH, Mo, etc. It has an acicular structure and would be higher strength and better toughness than pearlite iron. Due to the high alloy content and high casting stress, the acicular bainite ductile iron roll can obtain the ideal comprehensive performance by a centrifugal composite casting process.
Bainitic and bainitic / martensitic nodular iron are nodular grades alloyed with Cr, Ni, and Mo with higher Cr and Ni contents. Compared to pearlitic irons, acicular irons show higher strength, toughness and wear resistance. The rolls can be cast static or spun cast depending of the size of the working layer and the mill conditions. Application
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
China Dci Mill Roll High Strength Nodular Cast Iron. Compared with other nodular iron rolls, ncc rolls have unique material and heat treatment process ensuring they are good enough to replace the traditional cast steel rolls but with a better life.We control the carbide at a very low level less than 5 by reducing the crome down to 0.3, raising the silicon and applying isothermal quenching to.
