    摘要： 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).

    摘要： The invention relates to a method and an apparatus for controlling the pressure in the exhaust gas duct of a converter in a steel mill using a pressure control loop. In order to optimize the desired pressure setting for the pressure control loop in such a way that no excessive amounts of outside air are sucked in via the converter mouth, the desired pressure value is determined by adapting a raw value in accordance with the extent to which smoke or flames is/are formed at the mouth (120) of the converter (100).

    摘要： The present invention relates to a method of heating a non-ferrous and/or ferrous metal-containing stock in a furnace with a heating chamber, a charging door, an exhaust stream port and an exhaust stream duct, which comprises
    a) introducing fuel and an oxygen-containing gas into the heating chamber of the furnace through a burner so that a flame is formed,
    b) monitoring the signal of at least one optical sensor installed within the heating chamber and/or the exhaust stream duct,
    c) monitoring the change of the temperature T of the exhaust stream with time (dT/dt), and
    d) adjusting the fuel:oxygen ratio in step a) as a function of the signal of the flame sensor(s) and dT/dt in the exhaust stream,
    and, to an apparatus designed for implementing said method.
