Description Alloy cast steel roll is manufactured with high quality steel molten by arc furnace, due to the advanced casting and thermal traetment technique, such roll is of very high intensity. Owing to its excellent performances of anti-heat crack, tenacity and wear-resistance,t is appropriate to be used for rough and intermediate section steel rolling machine, heat rolling strip steel rough rolling machine stand and uesd as back-up roll for heat rolling strip steel. Its metallographic structure is made of pearlite or temper sorbite. The alloy steel rolls are widely used in the BD mill and roughing stands of heavy section mills, universal mills and rail& beam mills. This type of roll often has deep grooves in the roll body, so we make it by static cast. Due to the low carbon in the chemistry, we can hardly see graphite and carbide in the microstructure.2.Chemical CompositionGradeCSiMnPSCrNiMoVAS400.35-0.450.20-0.600.60-1.20≤0.035≤0.0302.00-3.500.00-0.800.30-0.700.05-0.15AS500.45-0.550.20-0.600.60-1.20≤0.035≤0.0301.00-3.500.30-1.000.30-0.700.05-0.15AS600.55-0.650.20-0.600.50-1.00≤0.035≤0.0300.80-1.200.20-1.500.20-0.60AS650.60-0.700.20-0.600.50-0.80≤0.035≤0.0300.80-1.200.20-0.500.20-0.45AS750.70-0.800.20-0.700.70-1.10≤0.035≤0.0300.80-1.50≥0.200.20-0.603.Mechanical PropertiesTensileStrength(kg/mm²)550-700BendingStrength(kg/mm²)750-1000Elongation(%)0.4-2.04.
