Nodular pearlitic rolls are widely used for hot rolling applications in different type of Roughing, Intermediate & finishing stands. The material consists of nodular graphite and carbides in pearlitic matrix.
Depending on the primary requirements (Whether thermal shocks/cracks, crack penetrations or wear resistance etc...) there are variety of Cr, Ni, Mo alloyed grades used considering the rolling mill operational conditions and groove / caliber design. The carbide is relatively higher in alloyed compared with standard grades. Heat treatment improves the resistance to thermal cracks as well. Sg Iron Rolls Manufacturers in India.
