EN-8 / EN-9 / EN-42 Forged Rolls
Forged steel rolls for demanding mill applications.
About this roll
Forged rolls: the material
Forged rolls made with centre holes for heat treatment and inspection — specified primarily for work rolls, back-up rolls, auxiliary and special rolls. Typical composition 0.85 C, 0.30 Mn, 0.30 Si, 1.75 Cr, 0.10 V, with molybdenum added and chromium varied for specific characteristics. Cold rolling involves extremely high pressures, and forged rolls deliver the strength, quality and wear resistance it demands — preferred in non-ferrous hot mills over iron rolls for their higher bending strength and resistance to metal pickup.

Production process
From melt to mill
Forged rolls
A steel ingot, forged under the press, then hardened and machined.
-
Charge mix
Steel scrap and alloys, weighed into the charge.
-
Melting
Sampled and adjusted in the ladle before pouring.
-
Ingot casting
Clean steel poured into an ingot mould.
-
Forging
The hot ingot is pressed to shape, closing the grain.
-
Heat treatment
Hardening and tempering on a controlled temperature cycle.
-
Rough machining
The forged skin is turned away to clean metal.
-
Necks & faces
Necks and faces turned to the mill's drawing.
-
Grinding
Ground to a fine finish under coolant.
-
Testing
Microstructure and hardness checked against the grade.
-
Certificate & dispatch
Crated and lifted with care, with its certificate.
