Abstract

The paper presents the results of operation of pilot batch of iron rolls manufactured via the method of centrifugal casting in dual-layer technique. Surface of roll barrel is cast of iron with high content of ledeburite alloyed with nickel, with fine laminar graphite and tempered beinite-martensite matrix, while core is made from spheroidized graphite. Wear resistance of iron rolls is higher compared with dteel rolls by 1.5 times.
keywords Work roll, iron, steel, surface layer, ledeburite, beinite, martensite, wear resistance, hardness, operation.
