Abstract

resumo patente de invenção: "molde de fundição contínua e método para fundição contínua de aço". molde de fundição contínua com a qual uma rachadura de superfície devido ao resfriamento não homogêneo da casca solidificada no período de solidificação inicial e uma rachadura de superfície devido a uma variação na espessura de uma casca solidificada que é ocasionada pela transformação de ferro ? para ferro ? em um aço de médio carbono associado, no qual uma reação peritética tende a ocorrer, pode ser evitada. um molde de fundição contínua (1) compreende uma pluralidade de porções separadas (3) preenchidas com um metal de baixa condutividade térmica formado pelo preenchimento de um metal, compreendendo uma condutividade térmica de 30% ou menos em relação ao cobre, em recessos côncavos circulares (2) possuindo um diâmetro de 2 a 20 mm de diâmetro que são formados na região da superfície do molde de cobre a partir de uma posição arbitrária maior que um menisco para um posição 20 mm ou menor do que o menisco, no qual a espessura de preenchimento (h) do metal nas porções preenchidas com o metal de baixa condutividade térmica é igual a ou menos que a profundidade dos recessos côncavos circulares.
