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 ≤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 ≤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 by a complete area of the projecting part (1s).
