High Speed Steel Mill Rolls

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.
