Abstract

"ARRANJO DE MONTAGEM PARA QUEIMADOR OU LANçA AUXILIAR". Trata-se de um invólucro de montagem e um arranjo de montagem aperfeiçoado para aparelhos utilizados na fusão, no refino e no processamento de metais, particularmente aqueles aparelhos adaptados para a siderurgia em um forno de arco elétrico, tais como queimadores, lanças e outros do gênero com capacidade de lancetamento do oxigênio supersónico e injetores ou algo do gênero para a introdução de material em partículas. O invólucro de montagem é refrigerado a fluido para sobreviver ao ambiente hostil do forno de arco elétrico e é projetado para ocupar o degrau entre a parede lateral e a soleira do forno sem nenhuma mudança substancial na estrutura do forno. O invólucro de montagem compreende uma pluralidade de canalizações de refrigeração a fluido que circundam uma abertura do aparelho e uma abertura do injetor que são formadas através do invólucro e adaptadas para a montagem de um aparelho e um injetor. O arranjo de montagem inclui a utilização do invólucro de montagem para montar um aparelho com capacidade de lancetamento de gás de oxidação supersónico e um injetor para o carbono em partículas em um forno de arco elétrico. Devido ao fato que o invólucro de montagem tem aproximadamente a largura do degrau, as aberturas de descarga do aparelho e do injetor são movidas para mais perto da superfície da massa em fusão e para o centro do forno, desse modo proporcionando uma maior eficiência. As aberturas de descarga serão agora estendidas para perto da borda do degrau de modo que o padrão de fluxo do gás de oxidação do aparelho não degrade o material da soleira ou um outro equipamento do forno montado nas proximidades e o padrão do fluxo de carbono do injetor agite suficientemente a escória para produzir a formação de espuma.
