Abstract

método para produzir aço num vaso. trata-se de um método para produzir aço num vaso, compreendendo o fornecimento de uma lança para insuflar oxigênio sobre a superfície do aço no vaso, a lança unida a um condutor de lança e em comunicação com um acelerômetro, o acelerômetro em comunicação de sinal com um módulo de aquisição de dados e um computador; carregamento do vaso com materiais para a produção de aço; descida de lança dentro do vaso e injeção de oxigênio dentro dos materiais; aquisição de um sinal por parte do acelerômetro indicativo de vibração da lança; processamento do sinal de vibração para determinar as frequências componentes de vibração da lança; comparação dos níveis das frequências componentes com valores de funcionamento desejados, e ajuste de, pelo menos, um parâmetro do processo de produção de aço com base no nível de, pelo menos, uma das frequências componentes. o parâmetro do processo de produção de aço a ser ajustado pode ser a vazão de oxigênio através da lança.
