From 1973 ACP Acciaieria di Cividate al Piano

Passion, and Technology in continuous evolution to support the production of special and stainless steels

Located in the heart of northern Italy on an industrial area of ​​235,000 square meters, ACP Spa offers maximum production flexibility and responsiveness in deliveries thanks to an organized and always well-stocked warehouse.

A.C.P. SPA. is a steel company that produces special and stainless steels through the production cycle of the electric steelworks. The Scrap Park consists of a totally covered area that allows the storage of raw materials for a volume of 35,000 m3. The selection of the main macro-classes of scrap (bound or not) following punctual quality checks, allows segregation in the n. 12 compartments available. Depending on the mixes calculated by the management system to obtain the chemical analysis required by the customer, operators package the baskets using cranes equipped with a magnet and a mechanical spider; these are weighed and loaded in the electric oven (E.A.F.) where the melting takes place and the slagging takes place.

After the tapping in the ladle and the deoxidation, the steel continues its production path through the secondary metallurgy that contemplates the phase of refining in the ladle furnace (L.F. 1 or L.F. 2) and of degassing at the vacuum degasser (V.D.). For the manufacture of very low carbon content stainless steels, the degassing station is used for decarburization thanks to the injection of oxygen by a special lance (V.O.D.). In the case of steels with particularly severe micro-inclusiveness cleaning requests, manual slagging is performed before the refining phase.

Finally, depending on the final destination of the job, the steel is poured into a source to produce ingot molds or in a continuous casting machine to produce billets for molding or rolling.

The Cividate al Piano factory  covers an area of ​​approximately 332,000 m², of which currently about 25,000 m² covered of the already authorized 70,000 m².
