Patent number: 5251882Abstract: A cooling element for shaft furnace walls including a metallic plate body with interior coolant-carrying tubes. The lower edge of the plate body includes a holding nose for refractory brickwork. The nose has at least one additional cooling tube. The cooling element according to the present invention may be assembled completely outside the furnace in a shop. The refractory brickwork consists of small bricks which are adhered or cemented to the plate body in concentric ring sections. The refractory bricks are advantageously provided with predetermined breaking notches and the layers of brick of the brickwork are provided with expansion joints. It is possible to use bricks with different thermal conductivities for the refractory brickwork.Type: GrantFiled: July 30, 1990Date of Patent: October 12, 1993Assignee: Man Gutehoffnungshutte AGInventors: Bruno Kammerling, Karl Spickermann, Urs-Peter Steiner

Patent number: 5244188Abstract: To absorb thermal expansions and relative movements, as well as to transmit torques, compensators, which are provided with an overtensioning device, are installed between the tuyere connections of a blast furnace and the hot-blast circulating duct. During the regular replacement of expendable parts of the tuyere connection, at least the elbow (4) must be removed as well, so that the intermediate pipe section (5) lined with refractory material will hang freely on the compensator (1). To achieve short replacement times, the compensator (1) is fixed according to the present invention by means of a locking device, and again disengaged on completion of the maintenance work. The locking device includes two flat bars (6), which are rigidly connected at the upper compensator flange (7). Threaded bolts (9), which extend into the flat bars (6) through openings (12), are fastened at the lower compensator flange (8).Type: GrantFiled: April 1, 1992Date of Patent: September 14, 1993Assignees: Man Gutehoffnungshutte Aktiengesellschaft, Steinfurter Eisenwerk GmbHInventors: Bruno Kammerling, Rainer Schmidt

Patent number: 5058288Abstract: The present invention pertains to a plumb bob device for determining the bed height of bulk material in a shaft furnace. The winding drum 1 for unwidning and rewinding a cable 5 or a chain with a plumb bob 6 suspended at its end is driven by a hydraulic motor 3. A displacement transducer 9 is driven by the shaft of the winding drum 1. The motor for driving the winding drum 1 is a so-called low-speed hydraulic motor 3. The displacement transducer 9 sends a signal associated with the actual measured depth to a pressure-proportional valve 10 directly, i.e., without an electrical control device. This valve presets a plumb bob holding pressure associated with the actual depth for the hydraulic motor 3.Type: GrantFiled: April 18, 1991Date of Patent: October 22, 1991Assignee: Man Gutehoffnungshutte AktiengesellschaftInventors: Ingo Herzog, Bruno Kammerling

Patent number: 4878655Abstract: In a throat stopper for shaft furnaces, in particular blast furnaces with two hoppers of which an upper hopper is rotatable through a drive device, the upper hopper is designed, by means of a stationary hood equipped with charging flap valves, as a sluice chamber to be closed pressureproof. For sealing the stationary hood relative to the rotatable upper hopper, there is disposed, at the hood, a peripheral flexible inflatable bellows. The bellows can be pressed against the wall of the upper hopper pneumatically or hydraulically. While material is being charged in the upper hopper, one of the charging valves is open and the bellows is pressureless. During, or shortly thereafter, the charging, the upper hopper is rotated. For during the lower hopper, the valves of the upper hopper are closed, bellows is inflated, and the upper hopper is hopper are closed, bellows is inflated, and the upper sluice chamber is pressurized.Type: GrantFiled: September 24, 1987Date of Patent: November 7, 1989Assignee: Man Gutehoffnungshuette, GmbHInventors: Bernhard Henneken, Bruno Kammerling, Eckhard-K.

Patent number: 4828228Abstract: A device for changing tap runners in shaft furnaces includes tap runners which have linings subject to wear and therefore such runners must be repaired regularly. Transport of the runner requires a considerable crane capacity with correspondingly heavy building construction. The device according to the invention permits transport of the tap runner without a casting room crane. Instead, the tap runner is raised or lowered between the mill floor, or another level, and a tapping platform by means of hydraulically driven traction elements taking support on runner supports arranged at tapping platform level.Type: GrantFiled: February 18, 1988Date of Patent: May 9, 1989Assignee: Man Gutehoffnungshuette GmbHInventors: Bruno Kammerling, Werner Rosker, Eckhard-Karl Scholz, Wolfgang Kowalski

Patent number: 4397450Abstract: An improved arrangement for securing a plate-type cooler in metallurgical furnaces is disclosed. The cooler comprises a cast body including embedded cooling pipes provided with protective tubes which are run into the cooler body and secured to the outlets of the cooling pipes. At a first level, at least one of the protective tubes is designed as a fixed support and the other tubes at the same level are designed as horizontally displaceable supports to allow for a thermal expansion. At a vertically opposite level, at least one of the protective tubes is designed as a vertically displaceable support and the other tubes extending at the same level are designed as movable supports.Type: GrantFiled: January 6, 1982Date of Patent: August 9, 1983Assignee: M.A.N. Maschinenfabrik Augsburg-Nurnberg AktiengesellschaftInventors: Bruno Kammerling, Franz Meier, Rainer Schmidt

Patent number: 4249723Abstract: A cooling device for use with a refractory lining in a smelting plant, such as a blast furnace and particularly a shaft furnace, includes an inner refractory lining, an outer steel jacket, and a plate member located between them. Preferably, the plate member is cast and anchoring members are cast into each plate member and extend only from the plate member surface facing toward the steel jacket. The anchoring member secures the steel jacket and plate members together and also holds them in spaced relation. Various embodiments of anchoring members can be used. In one embodiment a blind bore is provided within the anchoring member and a thermocouple extends into the blind bore from the steel jacket for measuring the operating temperature of the plate member.Type: GrantFiled: June 11, 1979Date of Patent: February 10, 1981Assignee: Gutehoffnungshutte Sterkrade AktiengesellschaftInventors: Bruno Kammerling, Axel Kubbutat
