HSS rolls have high hardness and good wear resistance at high temperature. These rolls are manufactured by Centrifugal Casting(CC) method and the roll core is filled with spheroidal graphite cast iron.
HSS rolls have high
hardness and good wear resistance at high temperature. These rolls are
manufactured by Centrifugal Casting(CC) method and the roll core is filled with
spheroidal graphite cast iron. The adequate chemical composition control and
proper heat treatment ensures the hardness of roll working layer to reach as
high as 80-85HSC. Uniformly distributed complex carbides of Vanadium, Tungsten,
Niobium and Molybdenum in the martensitic matrix ensures uniform hardness of
working layer and uniform wear out in the roll passes. These types of rolls are
used for finishing stands to increase productivity and improve surface quality
of rolled piece.
We need the following information to prepare quotation. 1. Roll drawing with machining details. 2. Hardness and weight of roll required. 3. Present roll's material and problem (if any). 4. Maximum and Minimum barrel diameter or chill depth. 5. Grade and model of rolling mill. 6. Stand number,type and capacity. 7. Pass schedule. 8. Working pressure and temperature.
