Abstract
Patente de Invenção: <B>"LANçA COMBINADA, DE USO VARIáVEL, COM CORPOS DE LANçA DE QUEIMADOR E SOPRADOR"<D>. Em uma lança para tratamento de fusões metálicas, que se encontram em tanques metalúrgicos, que apresenta um tubo de guia interno para condução de gases, particularmente oxigênio, com uma boca de lança na área de extremidade da cabeça, para soprar o gás, sendo que a lança apresenta bicos de queimador, formados na região da boca de lança na área de extremidade da cabeça, para realização de uma função de queimador, para passagem de um gás de combustão, deve ser obtida uma proteção dos bicos de queimador contra respingos de material. Para esse fim, está previsto que o tubo de guia (11) interno, com o primeiro envoltório de refrigeração (14), esteja formado como um primeiro corpo de lança (10) e os canais de gás de combustão (18), com o segundo envoltório de refrigeração (20), como um segundo corpo de lança (17), e o primeiro corpo de lança (10) está disposto de modo deslocável no segundo corpo de lança (17), entre uma posição de função de queimador levantada e uma posição de soprador rebaixada, na qual os bicos de queimador (19) estão cobertos pelo primeiro corpo de lança (10), que se salienta para baixo em relação à extremidade do segundo corpo de lança (17).
