Abstract
método para produzir um produto de chapa de aço laminada a quente lingotada continuamente de alta resistência, e, produto de chapa de aço laminada lingotado continuamente de alta resistência. métodos para produzir produtos de chapas de aço laminadas a quente lingotadas continuamente de alta resistência são descritos. os métodos incluem lingotar continuamente uma placa de aço e então laminar a quente com laminação de acabamento em um laminador de tiras a quente, temperar no laminador de tiras a quente para formar uma microestrutura predominantemente martensítica, e realizar uma etapa de ciclagem térmica incluindo encharcar a uma temperatura intercrítica seguida por manutenção a uma menor temperatura. os produtos de chapa de aço laminada a quente resultantes têm uma microestrutura compreendendo ferrita e austenita retida. os aços processados de acordo com a presente invenção exibem propriedades de resistência à tração máxima e alongamento total (uts ? te) combinadas favoráveis, e podem cair na categoria de aços avançados de alta resistência de geração 3, desejáveis em várias indústrias, incluindo fabricantes de automóveis.method for producing high strength continuously cast hot rolled steel sheet product, and high strength continuously cast hot rolled steel sheet product. Methods for producing high strength continuously cast hot rolled steel sheet products are described. Methods include continuously casting a steel slab and then hot rolling with finish rolling in a hot strip mill, quenching in the hot strip mill to form a predominantly martensitic microstructure, and performing a thermal cycling step including soaking the an intercritical temperature followed by maintenance at a lower temperature. the resulting hot rolled steel sheet products have a microstructure comprising retained ferrite and austenite. Steels processed in accordance with the present invention exhibit favorable combined maximum tensile strength and total elongation (uts ? te) properties, and may fall into the category of advanced generation 3 high strength steels, desirable in a number of industries, including steel manufacturers. automobiles.
