Union
Electric Steel Corporation was founded in 1923, has been
recognised as world leader in the forged hardened steel rolls.
The Forged Roll characteristics that determine roll performance
(microstructure, depth of hardness and residual stress) are
achieved by the proper combination of roll chemistry and heat
treatment.
Union Electric Steel is continuously developing new chemistry
and heat treatment combinations to provide new products for the
ferrous and non-ferrous industries.
The full Coil Static Induction hardening method that is unique
to Union Electric Steel optimises these critical roll
attributes.
Cryogenic Treatment of the ‘ as quenched’ roll is utilized for
roll applications that require a constat microstructure and
hardness from new to discard diameter.
A secondary melting operations Electro Slag Remelting (ESR) is
employed to further improve the cleanliness of the roll material
for certain mill applications like Aluminium Foil Rolling.
