Bulgaria’s Stomana Industry, part of the Sidenor group, has awarded Danieli a contract to supply new rolling mill equipment for its site in Pernik, Kallanish notes.
According to the supplier, the project includes installation of new upstream equipment to feed a Danieli K-Spool line relocated from the Sovel micro mill in Greece, which will be commissioned during winter, as well as the replacement of the existing abrasive disk saw.
“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,” it adds.
The new rolling equipment will feed the relocated Danieli K-Spool line, enabling the production of compact rebars in coil weighing up to 3.6t and covering diameters from 8 to 20 mm.
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.
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 metres. 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.
