Abstract: The sealed connection system between a tuyere of a shaft furnace, such as a steelmaking blast furnace, and an air blast pipe, in which a tip of the blast pipe is pressed towards a rear end of the tuyere, being centered thereon while still retaining freedom of pivoting movement relative thereto, including an added annular blast pipe seat, placed between the tip of the blast pipe and tuyere and immobile relative to the tuyere, the blast pipe tip resting against a rear face of the seat and an immobile gasket being placed between the seat and the tuyere such that the seat rests in sealed manner against a rear face of the tuyere, and a sleeve arranged around the contact zone between the blast pipe tip and the seat, is connected in sealed manner to the seat and to the blast pipe.

Abstract: The invention relates to an optical monitoring system (26) for monitoring operating conditions in a tuyere zone of a blast furnace. This system comprises a light deflecting device (40) with a peep sight (28) arranged in a first face (46) of the light deflecting device (40) and an optical sensor (30) arranged in a second face (48) of the light deflecting device (40). A light deflector (41) is arranged within the light deflecting device (40) for directing incident light from the tuyere zone towards the peep sight (28) and towards the optical sensor (30). The light deflecting device (40) comprises a housing (56) with a spherical body (60) rotatably arranged therein. The spherical body (60) comprises three passages: a first passage (62) which is, when the light deflecting device (40) is connected to the rear portion of the blowpipe (18), facing the tuyere for allowing incident light from the tuyere zone to enter the spherical body (60); a second passage (70) facing the peep sight (28); a third passage (72) facing the optical sensor (30). The first, second and third passages (62, 68, 72) are configured so as to meet each other within the spherical body (60). The light deflector (41) is arranged within the spherical body (60) at the intersection of the first, second and third passages (62, 68, 72). Furthermore, the light deflecting device (40) comprises an opening (76) in a third face (50) of the housing (56) for accessing the spherical body (60) for allowing rotation of the spherical body (60) within the housing (56). The spherical body (60) comprises a socket (78) facing the opening (76) in the third face (50). The opening (76) is a guiding slot (86) whose width is substantially the same as a diameter of the socket (78).
