Abstract

patente de invenção: "método de fundição contínua de aço". em um método de fundição de aço, usando um fundidor contínuo que inclui um par de polos magnéticos superiores e um par de polos magnéticos inferiores dispostos em lados externos de um molde, os polos magnéticos superiores voltados um para o outro com uma parte lateral longa de molde entre eles e os polos magnéticos inferiores voltados um para o outro com a parte lateral longa de molde entre eles, e um bocal de imersão com um bico de aço fundido localizado entre uma posição de pico de um campo magnético de cc dos polos magnéticos superiores e uma posição de pico de um campo magnético de cc dos polos magnéticos inferiores, o método compreendendo frear um fluxo de aço fundido com os campos magnéticos de cc aplicados respectivamente ao par de polos magnéticos superiores e par de polos magnéticos inferiores enquanto agitando um aço fundido com um campo magnético de ca aplicado simultaneamente com o par de polos magnéticos superiores, a intensidade de um campo magnético de ca aplicado aos polos magnéticos superiores é ajustada dentro do intervalo de 0,060 a 0,090 t e as intensidades de campos magnéticos de cc aplicados aos polos magnéticos superiores e inferiores são controlados dentro de faixas particulares de acordo com a largura da placa a ser fundida e da velocidade de fundição. como, é obtida uma placa de alta qualidade tendo poucos defeitos de bolhas, defeitos de fluxo e semelhantes.
