Resumo
Gerdau Ouro Branco´s plate mill started the operation in 2016 with high level technology. Stands out the capacity to produce plates with different thickness in the same as rolled. Therefore allows special service for sectors such as building structures, bridges construction, shipbuilding and mechanical applications. The purpose of this study is to present the first results obtained in this innovative product in Brazil. Some slabs of SAE J403 1045 and EN10025-2 S355JR+AR steel were rolled and were evaluated the dimensional tolerances, mechanical properties uniformity, grain size, surface and internal qualities. In addition, a correlation was observed between slab and plate thickness reduction and internal plate quality. The results show that this technology can be used with adequate performance for these steel grades in the current market.
