Intermediate Stands Cold Rolling Mill Rolls and Horizontal Centrifugal Casting Roll

Chilled Cast Iron Rolls for alloy indefinite intermediate stands

1. 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.
