Abstract: A shaft furnace, in particular a blast furnace, includes a metal jacket defining the furnace outer wall and a protective layer protecting the inner surface of the outer wall. At least one condition monitoring probe is arranged inside within the protective layer to monitor the latter. The condition monitoring probe is connected to a wireless module arranged outside the outer wall to transmit condition monitoring data. The wireless module is located inside a casing mounted to the outer surface of the metal jacket. The condition monitoring probe includes one or more conductive loops positioned at predetermined depths below the front face of the cooling plate body, or of the refractory lining, so that wear of the body, resp. refractory, can be detected by a change of an electrical characteristic of the loop(s) due to abrasion.

Abstract: A transfer or distribution chute for conveying bulk material by gravity flow includes an elongated chute casing defining a flow path for bulk material and a wear-resistant lining arrangement covering at least part of a flow path facing an upper side of the elongated chute casing. The wear-resistant lining arrangement includes a perforated plate affixed to the chute casing and has a plurality of perforations through which wear-resistant inserts having a body and an enlarged base are fitted in the perforations from a side opposite the flow path, such that their body protrudes through the perforation within the flow path, and their enlarged base abuts the borders of the perforation from the side opposite the flow path on one side and is held in place by the chute casing on the other side.

Abstract: The invention relates to a bellow compensator for a charging installation of a metallurgical furnace. The bellow compensator comprises an inlet end pipe 40 and an opposite outlet end pipe 42 and a bellow section 44 arranged between the inlet end pipe 40 and the outlet end pipe 42, the bellow section 44 being formed by a series of folds and allowing relative movement between the inlet end pipe 40 and the outlet end pipe 42. According to the present invention, a non-structural flexible liner 60, preferably wire mesh gasket, is arranged along an inner wall 62 of the bellow compensator and extends over at least some of the length of the bellow section 44. The non-structural flexible liner 60 has a first end 64 and a second end 66, wherein the first end 64 is fixedly connected to the inlet end pipe 40 and the second end 66 is fixedly connected to the outlet end pipe 42.

Abstract: A stave cooler for a metallurgical furnace includes a panel-like body having a front face for facing the interior of the metallurgical furnace, an opposite rear face, an upper face, an opposite lower face, and two side faces. At least one internal coolant passage is arranged within the panel-like body. The panel-like body is provided with a ledge on its front face extending between the side faces for being arranged in a horizontal plane. At least one protection element is provided for covering at least part of an upper face of the ledge. The protection element includes a first lateral portion, a second lateral portion, and a central portion. The lateral portions each include a widened front section and a narrow connection section. The panel-like body is provided with at least one through hole arranged for passing each of the lateral portions and the central portion of therethrough in turn.

Abstract: A blast furnace installation includes a blast furnace and a chute transmission gearbox; the blast furnace having a top cone with a top cone ring arranged thereon for receiving a connection flange of the chute transmission gearbox. The connection flange is directly fixed onto the top cone ring by fixing means for establishing a firm connection between the top cone ring and the connection flange. According to an aspect of the present invention, the connection flange is fixed to the top cone ring in three separated fixation regions (30, 30?, 30?), each fixation region including one or more fixing means. According to a further aspect of the present invention, the blast furnace installation also includes a flexible sealing element arranged around the perimeter of the connection between the top cone ring and the chute transmission gearbox.
