Abstract

a invenção descreve um forno de arco elétrico com uma função de pré-aquecimento de aço de sucata e um método para aliviar uma área fria de aquecimento de um forno de arco elétrico do tipo carregamento em parede lateral. o forno de arco elétrico com uma função de pré-aquecimento de aço de sucata abrange um corpo de forno de arco elétrico e uma câmara oblíqua de pré-aquecimento de aço de sucata, em que o ângulo incluído entre a câmara de pré-aquecimento de aço de sucata e o plano horizontal é de 30-65 graus, a câmara de pré-aquecimento de aço de sucata está conectada com o corpo do forno de arco elétrico, uma câmara de tubulação de coleta de poeira está disposta na extremidade superior da câmara de pré-aquecimento de aço de sucata, um ancinho de dente bloqueador está disposto na câmara de pré-aquecimento de aço de sucata e um mecanismo de direção está disposto sob o ancinho de dente bloqueador. a fumaça entra na câmara de pré-aquecimento de aço de sucata, penetra através do ancinho de dente bloqueador e do aço de sucata e, em seguida, é bombeada pela câmara de tubulação de coleta de poeira, de modo que o aço de sucata é pré-aquecido. posteriormente, o ancinho de dente bloqueador é aberto, o aço de sucata pré-aquecido desliza para o centro do corpo do forno de arco elétrico ao longo do fundo da calha da câmara oblíqua de pré-aquecimento de aço de sucata; o ângulo de queda do aço de sucata é alterado através da cooperação entre a câmara de pré-aquecimento de aço de sucata com ângulo de inclinação grande e o ancinho de dente bloqueador, de modo que o problema do acúmulo de material na lateral de um forno de arco elétrico do tipo carregamento em parede lateral é resolvido, a força de impacto do aço de sucata para o dispositivo é reduzida e a confiabilidade do dispositivo é bastante melhorada.
