Abstract
La presente invención se refiere a una lanza compuesta por una lanza superior (1t) y una sublanza (2) acoplada a la lanza superior (1t), que forma una parte saliente (1s) entre la lanza superior y la sublanza. La sublanza (2) de la presente invención se proporciona con un dispositivo protector (3) que comprende un extremo de acoplamiento (2c) que se abre hasta la cavidad (2v), en donde, cuando se encuentra en reposo, el dispositivo protector (3) está en una configuración inicial caracterizada por un diámetro externo máximo (D3o) que no tiene un diámetro mayor de 10 % que el diámetro (D2) de la sublanza (2) (D3o menor igual 1,1 D2), cuando la sublanza (2) está acoplada a la lanza, el dispositivo protector (3) se pone en contacto con la parte saliente (1s) y se deforma en una configuración deformada, lo que forma una superficie impermeable a metal fundido y escoria, que se extiende por un área completa de la parte saliente (1s).The present invention refers to a spear made up of an upper spear (1t) and a sublance (2) coupled to the upper spear (1t), which forms a projecting part (1s) between the upper spear and the sublance. The sublance (2) of the present invention is provided with a protective device (3) comprising a coupling end (2c) that opens up to the cavity (2v), where, when at rest, the protective device ( 3) is in an initial configuration characterized by a maximum external diameter (D3o) that does not have a diameter greater than 10% than the diameter (D2) of the sublance (2) (D3o less than 1.1 D2), when the sublance (2) is attached to the lance, the protective device (3) contacts the protruding part (1s) and deforms into a deformed configuration, which forms a surface impervious to molten metal and slag, which extends for a full area of the projecting part (1s).
