| These rolls have hard alloy iron on the working layer and soft grey iron or SG iron core depending upon the application. The shell matrix with proper distribution of carbides and graphite imparts high wear resis- tance, stability in shape and good surface finish. The softer core ensures good mechanical properties and resistance to thermal & mechanical loads |
|
| The matrix structure varies from fine pearlite to bainite depending on the alloy content. The desired hardness is obtained by changing the carbide/graphite balance which is achieved by a close control of chemistry and process parameters. The roll is tailor made for the mill and its application. The working surface is highly resistant to fire cracking spalling and wear. |
