“…Normalmente, os aços para transporte de óleo e gás apresentam-se como peritéticos (C: 0,08% -0,15%) microligados ao Nb, V, Ti combinados ou não. De acordo com Wolf [5], Super Heat, velocidade de lingotamento e refrigeração secundária seriam as variáveis a serem controladas de maneira a evitar trincas superficiais e sub superficiais [6,7] às quais devem ser removidas por escarfagem manual.…”

ResumoO desenvolvimento de placas de aços API necessita de preparação adequada das etapas produtivas na aciaria, de maneira a garantir tanto o atendimento aos requisitos do cliente que irá laminá-las, como as condições da última edição da norma API 5L. Este trabalho contém as premissas e as ações tomadas para o desenvolvimento do processo, desde o vazamento até o processo de lingotamento, sempre com foco na qualidade da placa lingotada. Finalmente, serão mostrados os resultados de desempenho das placas, submetidas às premissas e condições de desenvolvimento, nos laminadores dos clientes. Palavras-chave: Lingotamento contínuo de placas; Qualidade de placas lingotadas; Aços API; Processos de refino e lingotamento para aços API. DEVELOPMENT OF API STEEL SLABS, GRADES UP TO X65, AT GERDAU OURO BRANCO, FOR OIL AND GAS LINEPIPES AbstractDevelopment of API steel slabs demands suitable preparation of melt shop facilities, in order to ensure meeting of customer's requirements, as well as, the conditions stated on last edition of API 5L standard. This present work contains assumptions and actions have taken for process development, from ladle preparation to continuous casting process, always focusing on quality of cast slab. Finally, it will be shown performance results from slabs under those process development assumptions and actions at customers' mills.

Based on the achievement of high speed continuous casting in SGJT, fluid flow, heat transfer, and lubrication behavior were analyzed elaborately. The results indicated that wellbottom SEN with the angle of À208 together with FC mold could reduce the level fluctuation effectively. When FC mold was applied at 1.9 m min À1 , there was an increase of average heat flux about 0.06-0.1 MW m À2 . During heat transfer analysis, the empirical equation of heat flux was proposed and solidification crater end was validated by pin shooting method. Furthermore, a kind of mold powder employed in high speed casting was described and a new criterion of the consumption rate for high speed casting was put forward.
