Siemens to Supply Blooming Mill for Acciaierie Venete
05/01/2012 - Siemens VAI Metals Technologies has received an order from Italian steel producer Acciaierie Venete S.p.A. to extensively modernize the company's blooming mill in Camin. A new blooming stand including ancillary systems will be constructed and integrated into the existing installations.
Siemens VAI Metals Technologies has received an order from Italian steel producer Acciaierie Venete S.p.A. to extensively modernize the company's blooming mill in Camin. A new blooming stand including ancillary systems will be constructed and integrated into the existing installations.
The modernized blooming mill, which is scheduled to commence operation at the start of 2014, will enable greater reduction of cross-sections throughout the rolling process, improving the metallurgical properties of end products. As a result, additional processing steps such as forging can be dispensed with either in whole or in part, according to Siemens.
Siemens is constructing the blooming line from the exit point of the new bloom caster. From there, a transfer crane will transport the blooms either to the run-in roller table of the new reheating furnace or to the cooling bed. This will be realized as a walking beam system and will be able to provide different cooling profiles according to the product. Roller tables equipped with elevating and rotating fixtures will feed the new reheating furnace with the capability of hot charging. The reheating furnace will have two exits, ensuring a supply of ingoing material to the existing continuous rolling line during construction of the new blooming line.
A high-pressure descaler will be installed between the furnace and the blooming mill. The blooming mill itself is conceived as a duo reversing blooming stand with shifting units. The rolls have a length of 1500 mm and a diameter of 1060 mm. Per hour, the blooming stand can process around 110 tonnes of blooms with a weight of up to 10 tonnes and diameters of between 350 and 600 mm. Products with square cross-sections of 180 x 180, 240 x 250, and 280 x 280 mm and round stock with diameters between 180 and 315 mm are rolled from carbon and quality steels, and cropped by a hydraulic shear.
A roller table to the existing continuous long product rolling mill completes the blooming line's mechanical equipment. The scope of delivery also includes the electrical, drive and automation technology, including medium-voltage transformers for the blooming stand, AC main drives including two motors with a power output of 1,800 kW each, AC auxiliary drives, the complete level 1 automation, mechatronic components and a CCTV system.
Siemens is also responsible for the installation and commissioning and for customer training. Siemens will assist the customer in obtaining the required safety certification for the machines and ensuring the overall plant is in compliance with Italian and European regulations.
Acciaierie Venete is a private manufacturer of rods and profiles made of carbon and high-grade steels that has several production facilities in Italy. The company's headquarters is in Camin in the province of Padua. Acciaierie Venete produces around 1.5 million tonnes of steel every year.
