the contract represents the largest order for flat-products finishing lines in Europe placed with a single plant builder in recent years, and is intended to double the production capacity for finished strip at the Ravenna works. Danieli is particularly proud of this achievement, as it came at the end of a very close negotiation that involved all major plant builders, and also because it is a clear recognition of the good work Danieli performed in Ravenna during the execution of the hot-dip galvanizing line No. 2 project.

One of the most innovative coupled cold mills in Europe is started up at Acciaierie Arvedi in Italy, ensuring the best final product quality and production flexibility. For a new cold mill complex, Danieli Wean United, Buttrio, Italy, was awarded the order to supply the pickling and tandem cold rolling mill for an innovative facility capable of handling hot rolled material from 0.6 to 4 mm to be reduced by to 75% in thickness. The heart of the cold complex is a continuous pickling line with delivery tension reel. The pickling action is controlled by automation, a suitable preliminary preparation of the strips to be processed and the kinetics of the pickling liquor supplied at each pickling tank inlet and outlet. Long-stroke shifting is performed for both intermediate and work rolls and a meta-stable emulsion system is used to lubricate the bite, at least two separate systems are provided. Source

Chinese steel company Jiang Yin Xin Cheng Special Steel Works Co. (JYXC) has erected a new greenfield wide plate mill nearby its existing bar mill facilities. Danieli Automation designed and supplied all basic and technological L1 and L2 control systems for the entire plate mill. The new mill is providing JYXC a highly integrated and optimized automation system that ensures accurate and reproducible results in terms of product quality and improved plant efficiency. The automation system is able to process ingot rolling for high quality metallurgical products and plate rolling for special building and shipbuilding applications. A ExStream™ cooling section control capabilities extend the plant's production range to include specialty steel grades such as API grades. Source

The evolution of thin slab casting and rolling is studied in the context of Danieli, including first generation plants to recent applications, describing the different available solutions for specific market needs and gives an outlook on future potentials. The company has been working on the evolution of casting and rolling solutions to increase the production level, extend the product mix, increase the quality of the products, and add new products. Since the first pioneering applications, Danieli has adopted a thin slab caster that strongly differs from other technologies. Roughing stands and finishing stands are completely independent providing the proper optimal rolling conditions for each unit. Other works include the introduction of a fully continuous casting/rolling process, particularly suitable for the production of ultra thin gauges, consistently down to 0.8 mm. Source

A new wide plate mill complex has been started up by Danieli which is designed to fulfill the requirements for high productivity, yield, tight dimensional tolerances, enhanced mechanical properties and improved surface quality that are a must for the modern plant. Danieli has supplied all the technological line plant on turn-key basis with related automation and electrical equipment. Additionally, Danieli has supplied the main auxiliary plants such as roll shop, water treatment plant, compressed air system, laboratories, cranes etc. Due to the site location and the bad soil condition, the plant has been installed on a platform at seven meters higher than the ground level. A mathematical model is used to control the burners to obtain the optimum reheating curve for each steel grade. After the cooling phase is completed a nine-roll hot leveler is installed to correct any flatness defects. The output product quality meets and exceeds international standards. Source
