摘要： The invention relates to an upper or lower sealing valve arrangement for a shaft furnace charging installation. The arrangement comprises a shutter-actuating device (20; 120; 220; 320; 420) for moving a shutter (10) between a closed position in sealing contact with a valve seat (12) and an open position remote from the valve seat. The shutter-actuating device is of the dual-motion type, more specifically of the type configured to confer to the shutter a superposition of two rotations about substantially parallel axes (29; 39). It has a primary tilting arm (22) on a first tilting shaft (24) that defines the first axis (29) and is equipped with bearings (26) that support the primary tilting arm (22). A secondary tilting arm (32) carries the shutter (10) is connected to a second tilting shaft (34) that defines the second substantially parallel axis (39) and has bearings that support the secondary tilting arm (32) on the primary tilting arm (32). The shutter-actuating device has a mechanism (100; 200; 300; 400) configured to tilt the secondary tilting arm (32) when the primary tilting arm (22) is tilted. According to the invention, the first tilting shaft (24) is configured as hollow sleeve shaft and the shutter-actuating device (20; 120; 220; 320; 420) comprises a reference rod (42) extending through the first tilting shaft (24). This reference rod has a distal end portion to be connected to a stationary structure and a proximal end portion with a reference member (48; 248; 354; 454) that forms a kinematic reference frame for the driven side of the mechanism (100; 200; 300; 400).

摘要： The present invention proposes a hot blast control valve (10) for a metallurgical installation, in particular for controlling the flow of hot blast of a blast furnace. The hot blast control valve (10) comprises a metallic valve housing (12) with a refractory lining (20) in which a gas channel (22) is defined; and a valve member (24) rotatably arranged in the gas channel (22) so as to be able of varying a free passage in the gas channel (22) by rotation of the valve member (24) about a rotation axis (26) between an open position and a closed position. The valve member (24) has an envelope with rotational symmetry about the rotation axis (26) and has a through passage (28) arranged in the valve member (24) in a direction transversely to the rotation axis (26) of the valve member (24). The through passage (28) has a cross- section substantially identical to that of the gas passage (22). Furthermore, the through passage (28) is arranged in the valve member (24) so as to be aligned with the gas channel (22) when the valve member (24) is in its open position.

摘要： A multiple hearth furnace comprises a gas cooling system for its central shaft (20) and its rabble arms (26). This gas cooling system includes within the shaft (20) an annular main distribution channel (54, 54') for supplying a cooling gas to the rabble arms (26) and a central exhaust channel (56) for evacuating the cooling gas leaving said rabble arms (26). The gas cooling system further comprises an annular main supply channel (52, 52') surrounding the annular main distribution channel (54, 54') and being outwardly delimited by an outer shell (50) of the shaft. A cooling gas inlet (44', 44") is connected to the annular main supply channel (52, 52'). A cooling gas passage (60', 60"') between the annular main supply channel (52, 52') and the annular main distribution channel (54, 54') is spaced from the cooling gas inlet (44', 44"), so that cooling gas supplied to the cooling gas inlet (44', 44") has to flow through the annular main supply channel (52, 52') through several hearth chambers (12) before it flows through the cooling gas passage (60', 60") into the annular main distribution channel (54, 54').

摘要： A method of operating multiple hearth furnace (10) with a plurality of vertically aligned hearth floors (361, 362, 363, 364, 365), comprises in particular following steps. A first material is fed onto the uppermost hearth floor and moved over this uppermost hearth floor (361) before it falls through a drop hole (40) onto the next lower hearth floor. This first material is processed in this way from hearth floor to hearth floor down to the lowermost hearth floor (366). A second material is fed onto one of the hearth floors to be mixed into the first material. This second material (64) is moved separately from the first material in a separate annular zone (68) of the hearth floor onto which it is fed before it is mixed into the first material. The method allows to provide an efficient thermal preconditioning of the second material prior to mixing it into the first material without requiring any supplementary equipment therefore.

摘要： A multiple hearth furnace comprises a rabble arm (26) with a tubular structure (120, 124, 186) and a solid plug body (110). The latter is received in a socket (100) arranged in an arm fixing node (28). It has an axial through boring (132) and cooling fluid supply and return channels (146) arranged around this through boring (132). A clamping bolt (150) is rotatably fitted in the through boring (132). It has a bolt head (154), which can be brought by rotation into and out of hooking engagement with an abutment surface (162) on the arm fixing node (28). A threaded end (158) of the clamping bolt (150) sticks out of the through boring (132) at the rear end of the plug body (110). A threaded sleeve (160), which is screwed onto this threaded end (158), bears on an abutment surface (162) at the rear end of the plug body (110) for exerting a clamping force onto the clamping bolt (150).
