Product Description
High Speed Rolls
1.Centrifugal casting
2. ISO9000-2008
3. Casting spare part for rolling mill
4. For finishing stand
5. Good performance

1)Feature
The shell of centrifugal casting high speed steel roll is a high carbon alloy steel containing Cr, Mo, W, V and Nb. The microstructure consists of complex carbides embedded in a tempered martensitic martrix. Control of the carbon and a complex heat treatement allows the optimization of wear resistance, thermal fatigue resistance and oxide film formation, whilst maintaining low residual stress values.

2) Chemical composition
Material: HSS --- C:1.60-2.30, Si:0.30-0.90, Mn:0.20-1.80, W:1.00-4.00, V:2.00-6.00, Ni:0.30-1.50, Cr: 3.0-6.0, Mo: 3.00-6.00

3)Physical performance

Material: HSS   Barrel hardness:75-90 HSD    Tensile strength: ≥450Mpa

4)Application scope
HSS rolls are mainly used as the work rolls in the hot strip mills and the finishing stands of bar mills, rings of the universal section mills and finishing stands of the high speed bar mills and so on.

5)Hardness
Serial No.           Surface hardness of barrel roll                     Recommended for
1                           ≥95HSD                                                            work roll for pinch pass mill and finishing mill
2                           90-98HSD                                                        cold work roll of metal plate and strip
3                           75-90HSD                                                         cold work roll of metal plate and strip
