Abstract
"LANçA E APARELHO METALúRGICOS". Trata-se de um lança metalúrgica para introduzir gás de cima para dentro de um volume de metal em um recipiente que possui uma cabeça 12. A cabeça 12 possui pelo menos um ejetor 20 formado na mesma. O ejetor 20 compreende um esguicho Laval 24 cercado por uma passagem de gás de cobertura 30. Tanto o esguicho Laval 24 como a passagem de gás de cobertura 30 comunicam-se em suas extremidades próximas com uma câmara comum de suprimento de gás 22. A passagem de gás de cobertura 30 comunica-se com a câmara 22 via um primeiro membro de orifício anular 38 que determina a porcentagem de divisão do fluxo de gás através da câmara entre o esguicho Laval 24 e a passagem de gás de cobertura 30.
