Abstract

MéTODO PARA CONTROLAR O RESFRIAMENTO DE LáMINA DE AçO. A presente invenção refere-se um método para controlar o resfriamento de uma lâmina de aço caracterizado por controlar a temperatura do término do resfriamento em um processo de resfriamento a partir de uma temperatura Ae3, ou acima, da lâmina de aço, durante o qual; obtendo preliminarmente as entalpias (H<sym> e H<244>) de uma fase austenita e de uma fase ferrita, respectivamente, em algumas temperaturas, obtendo uma entalpia dinâmica (Hsys), definida pela fórmula (1), com uma fração não-transformada (X<sym>) de austenita, de acordo com um padrão de temperatura alvo, prognosticando a temperatura pelo uso de um gradiente desta entalpia dinâmica com relação à temperatura como um aquecimento especifico dinâmico e controlando o resfriamento da lâmina de aço: Hsys = H<sym> (X<sym>)+H<244>(1-X<244>) fórmula (1)
