INTRODUCTION
A common problem for several steel producers is the way to modernize and improve the production plants and schedules without a deep impact on the mechanical layout avoiding a too heavy financial charge.
In the project we detail below we'll describe AIC's strategy that allows to perform a complete electric Revamping of ORI Martin – Ceprano Rolling Mill (Frosinone, Italy), carried out in two phases planned during capital plant stops (August and Christmas period).
In the first step all activities concerning auxiliary services were implemented, while during the second step all tasks about rolling mill area and safety system were performed, preserving the existing mechanical equipments.
ORI Martin is a primary group, specialized in high quality long products steel production and its core business is the long products special steels (SQB) for use in the automotive indutry.
Ori Martin headquarters are situated in Brescia and houses a melting and rolling plant for the hot production of long product steels for mechanical applications, while the factory in Ceprano is focused on construction steels (SQB).
Founded in 1974, the revamped plant is specialized in the hot rolling of billets (mainly produced in the meltshop of Brescia) for the production of straight bars (from Ø 8mm up to Ø 32mm), wire rods (from Ø 8mm up to Ø 17mm) and coiler bars (from Ø 18mm up to Ø 32mm).
