Cast Steel Rolls

In the steel and metallurgy industries, rolls are among the most critical components of rolling mills. Their performance directly determines product quality, production efficiency, and overall cost. Among various roll materials, cast steel rolls stand out for their high strength, toughness, and durability, making them a preferred choice for many steel plants worldwide.

1. What Are Cast Steel Rolls?

Cast steel rolls are produced by casting molten steel into roll molds, followed by heat treatment and precision machining. Compared with cast iron rolls or forged rolls, cast steel rolls offer several advantages:

• High strength and toughness – capable of withstanding heavy loads and impact.
• Excellent wear resistance – providing longer service life under demanding conditions.
• Wide applicability – suitable for both hot rolling and certain cold rolling processes.

These features make cast steel rolls indispensable in the production of steel, aluminum, copper, and other industrial metals.

2. Main Types of Cast Steel Rolls

Cast Steel Rolls

• A steel-based roll formed by casting, with a carbon content ranging from 0.4% to 2.1%.
• The carbon content of special-purpose rolls may fall outside this range.
• Commonly used in small and medium-sized mills for rough rolling.

Alloy Cast Steel Rolls

• A roll cast from alloy steel with a total alloying element content not exceeding 5%.
• Alloyed with elements such as chromium, molybdenum, nickel, and vanadium.
• Improved wear resistance and thermal fatigue resistance, ideal for high-temperature, high-stress conditions.

 Adamite Rolls

• A cast steel roll with a carbon content of 1.0%–2.3% and an appropriate amount of alloying elements.
• A hybrid between cast iron and cast steel.
• Combines the wear resistance of cast iron with the toughness of cast steel. Widely used in hot rolling mills for roughing stands.

Graphitic Cast Steel Roll

A cast steel roll with an appropriate amount of graphite in its structure, a carbon content of 1.2%–2.5%, and a silicon content of more than 0.8%.

High Chromium Cast Steel Roll

A cast steel roll whose roll body working layer has a chromium content of more than 8%.

Alloy Tool Steel roll

A roll whose roll body working layer is made of tool steel with high alloy content and high hardenability.

High-Speed Steel Rolls (HSS)

A cast steel roll whose roll body working layer has an alloy content of more than 10%, a structure with a large amount of carbides, and a secondary hardening effect during high-temperature tempering.

High Carbon High Speed Steel Roll

A cast roll that has the structural characteristics of high speed steel rolls, contains various composite carbides, and simultaneously has a certain amount of graphite phase.

3. Applications of Cast Steel Rolls

Cast steel rolls are widely applied in:

• Steel industry – plate, bar, and wire rod rolling.
• Non-ferrous metals – rolling of aluminum, copper, and other alloys.
• Heavy machinery – high-load rolling equipment.
