Abstract

resumo patente de invenção: "método de fundição de aço contínuo". método de fundição em condições para redução moderada que são determinadas com a espessura de um filamento de placa de modo a evitar que a segregação central ocorra no filamento devido a uma taxa de prensagem insuficiente ou que fissuras internas ocorram no filamento devido a uma taxa de prensagem alta. quando um filamento (10) que tem uma espessura de 160 mm a 350 mm e uma largura de 1.600 mm a 2.400 mm é continuamente fundido enquanto uma região do filamento que se estende a partir de um ponto em que uma porção intermediária no sentido da espessura de filamento tem uma fração de sólido de 0,1 até um ponto em que uma porção intermediária no sentido da espessura de filamento tem uma fração de sólido equivalente a uma fração de sólido de limite de fluxo é prensada em uma zona de redução moderada (14) na qual múltiplos pares de cilindros de suporte de filamento estão dispostos, a espessura de filamento (d), a taxa de redução (z) da zona de redução moderada e a velocidade de retirada de filamento (v) satisfazem as expressões (1) e (2) abaixo, em que a denota um coeficiente de espessura (sem dimensão), do denota uma espessura (mm) de um filamento padrão em uma posição imediatamente abaixo de um molde e ß e ? são coeficientes determinados por uma largura w (mm) do filamento: 0,3/(v x a) < z < 1,5/(v x a) ... (1), e a = ß x (d/do) + ? .. (2).
