Abstract

resumo patente de invenção: "método para fusão de aço". a presente invenção refere-se a um método para a fusão de aço em um forno de arco elétrico (eaf). um resíduo quente (15) é fornecido no eaf. a sucata de metal (16) é carregada no eaf. a sucata de metal (16) é fundida no eaf. de acordo com a invenção, a massa do resíduo quente (15) em relação à massa da sucata de metal que está inicialmente além da superfície do resíduo quente é de um determinado mínimo. esse mínimo é 0,75 vezes a relação entre o calor necessário para fundir a sucata de metal além da superfície do resíduo quente (15) e o calor que pode ser tirado do resíduo quente sem ele ser solidificado quando um cálculo de equilíbrio de calor teórico é aplicado como definido em uma fórmula.
