Stomana Industry S.A., part of the SIDENOR Group, awarded Danieli a contract to supply new rolling mill equipment for its site in Pernik, Bulgaria.

The project includes installation of new upstream equipment to feed a Danieli K-Spool line relocated from the Sovel micromill in Greece (where the new Danieli 8 ton K-Spool line will be installed and commissioned during winter), together with replacement of the existing abrasive disk saw.

Danieli’s scope of supply includes two preboxes, pinch rolls, a crop/chopping shear, an eight-pass finishing block complete with ring manipulator, and six water boxes with associated valve benches, lubrication and hydraulic systems.

Also in the package will be a new abrasive disk saw with a 1.6-m-diameter disk, entry and exit roller tables, a short-bar collection system, and a wheeled stop-on-beam, together with complete electrical and automation systems, engineering, training, advisory services and delivery.

The new rolling equipment will feed the relocated Danieli K-Spool line, enabling the production of compact rebars-in-coil weighing up to 3.6 t and covering diameters from 8 to 20 mm.

The project is designed for thermomechanical rolling combined with Danieli Soft Quenching (SQ) technology — a patented, multistage controlled-cooling process that enhances metallurgical homogeneity, mechanical-property consistency, dimensional stability and production repeatability.

The new abrasive disk saw will replace the existing unit and will be used for cutting SBQ rounds from 20 to 130 mm diameter and lengths from 5 to 12.1 m. Featuring an improved bar-locking system, a more powerful drive, extended disk life, faster disk changing time and easier access for maintenance, the new installation will support higher-quality and increased SBQ production.

A new automation system will be supplied to integrate seamlessly with the existing mill infrastructure, improving process control and operational efficiency.

With the integration of the former Sovel spooling line and the installation of the new saw, STOMANA will expand its capability to serve growing demand for compact rebar coils and higher-quality SBQ products.
