Abstract
"PROCEDIMENTO E EQUIPAMENTO PARA O ENVOLVIMENTO DE UM ARCO VOLTAICO". A presente invenção se refere a um procedimento para envolver um arco voltaico (22) que está centelhando num forno de arco voltaico (10) por meio de escória espumosa (S), a qual é produzida pela introdução de portadores de carbono na escória que se encontra na parte superior do banho de aço (M) , sendo que a emissão de som é detectada e utilizada para comandar a introdução do carbono espumoso. Neste procedimento, o espectro de amplitude do som é detectado como estalidos (emissão de som sob forma de estampido). As amplitudes que estão relacionadas com o estalido são avaliadas, trazidas para um patamar semelhante e transmitidas para uma unidade de computação (43). Na unidade de computação (43), os valores medidos avaliados são acessados para o comando da escória espumosa S e são utilizados, quando um valor predeterminado for ultrapassado ou não for alcançado, para influenciar a quantidade (32, 33) de portadores de carbono a ser adicionada para fazer espumar a escória. A presente invenção também se refere a um equipamento adequado que lhe corresponde. Figura 1.
