IWSQ2016Scope

The surface quality of billets, blooms and slabs is a particularly important issue in order to assure the required surface quality of the final rolled products. This aspect is becoming increasingly significant especially nowadays, when a lot of steelmakers are refocusing their activity on the search for better surface quality or new specialty steels requiring high quality surface features. Moreover, the production of large size semis products and the use of the electromagnetic equipment have to be carefully performed to avoid any detrimental effects on the surface qualities.This international meeting aims to share the knowledge about the improvement of the surface quality of the continuously cast products and this scope will be achieved by clear expositions about:• the state of the art on the defect analysis;• the root cause of the defects;• presentation of innovative lubricating products;• updated criteria for the definition of the correct casting parameters;• application of electromagnetic devices.A focal point of the workshop will be the Panel Discussion on Casting Powders Technology with Prof. Ken Mills (Dept. of Materials, Imperial College) and two major experts of the field: Dirk Eckhardt (former Manager, Technical Dept., Stollberg GmbH) and Wilhelm Hubsch (former Product Fluxes Manager, Metallurgica GmbH).

AIM is looking forward to welcoming you in Bergamo!

IWSQ2016Venue

The Conference will be held in Bergamo. Bergamo greets visitors with its Venetian Walls. Surrounded by rivers and lush, verdant valleys, crossed by paths that widen to Parco dei Colli, the area’s largest park, the city looks like a lounge filed with art, culture and nature, with a fascinating and complex history just waiting to be shared with others. Also known as the “Città dei Mille”, or City of the Thousand, in honour of those 180 Bergamo young men who departed from here in 1860 to participate in the expedition “of the thousand” led by Garibaldi that resulted in the unification of Italy, Bergamo’s streets bear signs of its ancient history, a story that’s still in the making.Among museums, works of art and splendid natural surroundings, cobbled streets and buildings with beautiful facades, religious and contemporary artistic treasures and masterpieces of taste and wine, events that are held throughout the year: the “upper and lower” city reveals a mixture of pleasant surprises and unexpected encounters, such as those with Gaetano Donizetti, the great composer of international renown, Bartolomeo Colleoni, the Bergamo leader who served under the Republic of Venice and Lorenzo Lotto, among the most famous Italian Renaissance artists who lived and worked in Bergamo for over a decade.
