Abstract

resumo patente de invenção: "método para a produção de material de aço". método para a produção de um material de aço, em que ca é adicionado ao aço fundido em uma quantidade dentro da faixa que satisfaça uma fórmula prescrita. após o refinamento secundário, a quantidade de al2o3 no aço fundido pode ser analisada e, então, casi pode ser adicionado ao aço fundido em um recipiente. a quantidade de al2o3 no aço fundido pode ser analisada usando espectroscopia de emissão atômica de descarga por centelha a seguir. a razão da intensidade de emissão de luz do alumínio para a intensidade de emissão de luz do ferro é determinada para cada um dentre uma pluralidade de pulsos de descarga. uma fração de alumina é computada usando uma fórmula prescrita, e as razões de intensidade de emissão de luz obtidas dos pulsos de descarga são dispostas em ordem ascendente. uma razão de intensidade de emissão de luz em uma dada posição igual ou menor que 30% do número total de pulsos de descarga é usada como uma razão de intensidade de alumínio representativa. então, uma razão de intensidade de alumina (= a fração de alumina x a razão de intensidade de alumínio representativa) é computada usando o produto da fração de alumina computada e a razão de intensidade de alumínio representativa, e a quantidade de alumina (no aço) pode ser computada usando a fórmula de relações entre a razão de intensidade de alumina e a quantidade de alumina (no aço) determinada por análise química.
