Abstract

LANÇAS PARA INJEÇÃO DE TOPO SUBMERSA. A presente invenção está correlacionada uma lança (10), para conduzir uma operação pirometalúrgica através de injeção de lança de topo submersa ( TSL) , em que a lança ( 10) apresenta pelo menos um tubo interno ( 12) e um tubo externo (14), que são substancialmente concêntricos. A saída inferior do tubo interno ( 12) é estabelecida em um determinado nível com relação à extremidade da saída inferior do tubo externo (14), exigida para operação pirometalúrgica. A lança (10) inclui ainda uma manta (22), através da qual o tubo externo ( 14) se estende, a qual é montada e se estende ao longo de uma porção superior do tubo externo ( 14) , def in indo com o tubo externo ( 14) uma passagem ( 2 8) , ao longo da qual um gás é capaz de ser suprido para circular na direção da extremidade de saída do tubo externo ( 14), para descarregar exteriormente a lança (10). A manta (22) é ajustável longitudinalmente em relação ao tubo externo ( 14) , de modo a possibilitar uma substancial manutenção ou variação de um espaçamento longitudinal entre as extremidades de saída da manta (22) e do tubo externo (14).
