Abstract

1. Tuyere for a blast pipe of a fusion/reduction furnace, particularly a blast furnace, provided with means for heating the blast comprising a plasma torch (8), which tuyere comprises an outer metal wall (1) equipped with means (10) for cooling by circulating a cooling fluid over its outer surface and an inner lining (2) in a hard refractory material, which tuyere consists of a cylindrical body (4), of a frustum of a cone (5) whose major diameter side is connected to the body, and of a nose (6) which is substantially cylindrical and connected to the minor diameter side of the frustum of a cone, the body (4), the cone (5) and the nose (6) being disposed one after the other and coaxially, which tuyere is characterized in that it comprises a layer of an insulating fibrous material (3) disposed between the outer metal wall (1) and the inner refractory (2).
