Cast Steel Rolls Are Available In Wide Chemical Compositions Varying Fr Hypo Eutectoid To Hyper Eutect Steels.
Alloying Combination Of Different Element Like Cr, Ni & Mo Are Normally used To Achieve The Desired Physical and Mechanical Properties.
In View Of The Demanding End Us Requirement These Rolls Can Not B Used In An As Cast Condition. When Coarse Grain Pearlitic Structure Wit Cementite And Ferrite In A Continuous Network Is Normally Obtained.
The Rolls Are Subject To Specially Designed Heat Treatment Cycles To Arrive At The Optimum Microstructure Configuration With Fine Pearlite And Uniformly Distributed Suitable For The Final Application.
