Siemens VAI Metals Technologies has received an order from Riva Acciaio to modernize the roughing train of the medium section mill in Sellero in Italy.

The scope includes the complete process and mechatronics packages for the blooming stand, the electric and automation systems and the erection. The objectives of the project are to boost productivity and expand flexibility in respect of operation modes and product change. The modernization is to be completed in the second half of 2012.

Riva Acciaio's medium section mill in Sellero, in the province of Brescia, was supplied by Siemens in 1996. It has an annual capacity of around 250,000 tonnes and is designed to produce squares, flat bar and U-sections with widths of up to 340 millimeters and round bar with diameters of up to 160 millimeters.

For the roughing mill of the rolling line, Siemens is to supply a reversing Red Ring blooming stand and a reduction group, the roller tables and equipment for shifting and rotating the incoming blooms. The blooming stand enables symmetrical roll gap control and is equipped with a quick change device for changing rolls. With this, the operator can quickly switch the rolling line to a different final product.

The scope of supply also encompasses the main and auxiliary drives, including the motors and the basic automation. Siemens will also install a CCTV system and will be responsible for supervising installation and commissioning.

Riva Acciaio is a wholly owned subsidiary of Riva Fire SpA. The Riva Group has more than 35 production sites in Europe, North Africa, and Canada and produced around 14 million tonnes of raw steel in 2010.
