The forged steel work roll is solid-forged roll made of alloyed steel, close to eutectoid and hypereutectoid steel. It has a good combination with hardened surface which creates a strengthened working layer, heat check and tough core resistance to breakage. Heat treatment reduces and equalizes residual internal stress.
Feature
High Hardness
The high hardness and great depth of hardness are needed for cold reduction mills.
Increased Heat Resistance
With the strong heat resistance, the roll can be capable of retain high hardness with the roll under continuous and constant heating rate.
No Metallurgical Flaws
High Resistance
It is also can ideal hardness and high resistance to spalling, surface flaws, cracks, scaling,etc.
No Microstructure Flaws
The surface microstructure consists of fine grain martensite and finely dispersed chromium carbides.
Application
Tandem mills
Reversing cold rolling mills
Temper mills
Forged Steel Work Rolls Used In Rolling Mills
Hot Rolling Mill
The forged steel work rolls can be used for hot plate mill and these rolls have the features of rich in alignment, high toughness and strong wear ability. They are made of forges steel blanks and can withstand the special heat treatment for excellent hardness.
Cold Rolling Mill
The work roll can be used for cold rolling mill. The forged rolls are produced by steel-making, refining and forging. A homogenous highly dispersed structure provides mechanical properties of the internal layer for complicated heat treatment. It becomes easier for exceptional performance by using the forged rolls which are applied in cold rolling mill.
Forged steel roll is an important mill roll with its outstanding working performance. It can be used as work roll, back up roll and intermediate roll with its high hardness, superior yield strength and high resistance to spalling, fatigue, scaling, etc.
