Abstract

SE DESCRIBE UNA LANZA UTILIZADA PARA INTRODUCIR REACTANTES DENTRO DE UN METAL FUNDIDO, EJM. ACERO Y SIMILARES, CUYA VIDA HABIL ESTA MEJORADA Y COMPRENDE UN TUBO INTERNO (21) Y UN BASTIDOR REFRACTARIO (25), EL TUBO TIENE UNA ENTRADA (22) ADYACENTE A UN EXTREMO Y UNA SALIDA (26) ADYACENTE AL OTRO, DONDE EL REACTANTE SE PUEDE INYECTAR A TRAVES DE LA LANZA. EL TUBO INTERNO ESTA SEPARADO DEL EXTERNO PARA OFRECER EN MEDIO UN HUECO DE AIRE (24) ENTRE LOS DOS TUBOS, EL BASTIDOR TIENE SOBRE EL TUBO EXTERNO UN CONDUCTO DE GAS (27) QUE SE EXTIENDE ENTRE AMBOS TUBOS EXTERNO E INTERNO Y QUE TIENE SUS SALIDAS ADYACENTES A LA PARTE DE LA SALIDA (26) DEL TUBO INTERNO, DONDE EL GAS QUE PASA A TRAVES DEL CONDUCTO PUEDE SALIR A LA ATMOSFERA A TRAVES DEL HUECO DE AIRE ANULAR (24).A SPEAR USED TO INTRODUCE REACTANTS WITHIN A CAST METAL, EJM, IS DESCRIBED. STEEL AND SIMILAR, WHOSE LIVING LIFE IS IMPROVED AND INCLUDES AN INTERNAL TUBE (21) AND A REFRACTORY FRAME (25), THE TUBE HAS AN INLET (22) ADJACENT TO ONE END AND AN OUTPUT (26) ADJACENT TO THE OTHER, WHERE THE REACTANT CAN BE INJECTED THROUGH THE SPEAR. THE INTERNAL TUBE IS SEPARATED FROM THE EXTERNAL TO OFFER A AIR HOLE IN THE MIDDLE (24) BETWEEN THE TWO TUBES, THE FRAME HAS A GAS DUCT (27) OVER THE EXTERNAL TUBE, WHICH EXTENDS BOTH EXTERNAL AND INTERNAL TUBES AND HAS ITS EXITS ADJACENT TO THE OUTLET PART (26) OF THE INTERNAL TUBE, WHERE THE GAS PASSING THROUGH THE DUCT CAN EXIT TO THE ATMOSPHERE THROUGH THE ANNULAR AIR HOLE (24).
