Chilled Cast Iron Rolls for finishing stands for bar wire and section mills

ALLOY INDEFINITE CHILLED CAST IRON ROLLS

◆ SUMMARY

It is a kind of cast iron roll with fine intercrystalline graphite evenly distributed throughout its working layer.

It is shaped by Centrifugal Casting Machine, or by gravity casting.

◆ CHARACTERISTICS

◇ In its microstructure, the size, shape and distribution of graphite and carbide are controlled by chilling

effect and the contents of alloy elements.

◇ The matrix microstructure can be changed from Bearlite, Bainite to Martensite through adding alloy

elements such as Manganese, Nickel, Chromium Molybdenum etc.

◇ The small amount of fine graphite in its matrix enhances the roll’s resistance to brittle crack, thermal crack and its wearability.

◇ The small hardness gradient in roll’s working layer is suitable for usage in intermediate and finishing stands for bar, wire and section mills.

◆ APPLICATION

Used in intermediate or finishing stands for bar, wire and section mills.
