Abstract

MéTODO PARA CONTROLAR A FORMAçãO DE BOLHAS, BANHO DE METAL FUNDIDO EM UM RECIPIENTE METALúRGICO E DISPOSITIVO PARA EXECUTAR O REFERIDO MéTODO. O método de acordo com a invenção consiste em introduzir um gás de agitação através do fundo do recipiente (1), em receber uma vibração mecânica mensurável por pelo menos um sensor fixado no recipiente ou na armação de apoio do mesmo, em filtrar os sinais de vibração detectados desse modo por um filtro de alta passagem (13a) e, preferivelmente, por um filtro de baixa passagem (13), em submeter os referidos sinais de vibração à amostragem e digitalização (15) para expor os mesmos a uma segunda filtração, que é digital, e está calibrada sobre as respostas de vibração do recipiente, em seqüenciar as referidas respostas, em expor cada seqüência ao cálculo (17) de um quadrado médio móvel temporal, em extrair o valor efetivo total RMS (para "Quadrado Médio de Raiz") do sinal de vibração medido do mesmo, sendo que o referido valor efetivo é usado para controlar a razão de fluxo do gás de agitação fornecido ao recipiente. A referida invenção pode ser usada para o setor de agitação de recipientes de aciaria, conversores, processos de RH, fornos de arco voltaico elétricos etc.
