What is Forged Roll?
Forged roll are rolls produced by forging ingots. Forging can forge metallurgical defects such as looseness and shrinkage porosity inside the ingot, and crush the coarse casting structure to obtain high-quality rolls with dense structure and uniform composition.
What are features of Forged Rolls ?
Improving mechanical properties
After the casting structure is deformed by hot processing by the forging method, due to the deformation and recrystallization of the metal, the original coarse dendrite and columnar grains become the equiaxed recrystallization structure with finer grains and uniform size, so that the original segregation, looseness, porosity, slag inclusion and other compaction and welding in the steel ingot, its structure becomes more compact, and the plasticity and mechanical properties of the metal are improved.
Longer service life
Forging can ensure the continuity of the metal fiber structure, make the fiber structure of the forging consistent with the shape of the forging, and the metal streamline is complete, which can ensure that the parts have good mechanical properties and long service life.
Material of Forged Rolls
Forged rolls have better strength, toughness, surface hardness uniformity and fatigue resistance than similar cast rolls. In order to meet different requirements, different alloying elements can be added to the forging steel to improve the performance of the forged rolls. A certain amount of carbon and alloying elements have different effects on the structure and properties of forged rolls as follows.
Carbon
Carbon can increase roll hardness and strength, reduce plasticity, and improve wear resistance.
Manganese
Manganese can increase hardenability and strength.
Silicon
Silicon acts as a deoxidizing agent and increases strength.
Chromium
Chromium increases hardenability and strength, and improves wear resistance.
Molybdenum
Molybdenum can increase hardenability, strength and hot hardness.
Vanadium
Vanadium controls the grain size of steel and increases strength.

Comparison of forged and rolled pieces
The difference between the axial and radial mechanical properties of the forged pieces is smaller than that of the rolled pieces, that is, the isotropy of the forged pieces is much higher than that of the rolled pieces, so the life of the forged pieces is much higher than that of the rolled pieces.
In terms of the degree of deformation, the deformation degree of forged pieces is much greater than that of rolled pieces, that is, the effect of breaking eutectic carbide by forging is better than that of rolling.
In terms of processing cost, the cost of forging is much higher than the cost of rolling, for some key parts, workpieces that bear large loads or impacts, workpieces with complex shapes or very strict requirements, or must be processed by forging technology.
Forged pieces have a complete metal streamline, and the integrity of the metal streamline is destroyed by mechanical engineering after rolling, which greatly shortens the life of the workpiece.
