摘要:
The campaign lives are extended and the risks of process gas leaks past seals are reduced by improved stave coolers that each hang together inside steel shelled furnaces by a single neck extended out through a steel jacketed collar. All the coolant circuits inside the stave cooler are collected and grouped together to pass inside through the one collar. The steel in the collar is matched to the steel used in the containment shell, and a matching steel weld seals them together. Thermal stresses are thereby prevented from accumulating over separation distances as a consequent of the steel's coefficient of expansion. A single point of penetration has no separation distance to another.

A panel cooled with a fluid, for metallurgic furnaces, includes a first chamber having a face which, in assembly conditions, is configured to face an interior of a metallurgic furnace and an opposite face in thermal contact with a face of a second chamber whose opposed face is configured to face, in assembly conditions, an external part of the metallurgic furnace. The first and second chambers are mutually independent. The first and second chambers each include an inlet and outlet of a cooling fluid. The panel has a first working configuration in which the first chamber is passed by a first cooling fluid and the second chamber is passed by a second cooling fluid different from the first cooling fluid, and a second working configuration in which the first chamber is passed by the second cooling fluid and the second chamber is passed by the first cooling fluid.

The present invention relates to a method for producing a heat exchanger. The heat exchanger comprising at least one heat conducting conduit for passage of a first medium and at least one block of an open cell porous medium for passage of a second medium. The method comprises providing at least one groove in the open cell porous medium. Thereafter, the porous medium is bent in a direction such that at least part of the grooves are opened and heat conducting conduits are applied in this at least one opened groove. Thereafter, the porous medium is rebend such that the heat conducting conduits are locked in said open cell porous medium.

Metallurgical processing installation comprising a metallurgical vessel lined internally with water cooled panels. A vessel access tower (61) fits around vessel (11) and supports a coolant flow system (62) to provide for flow of cooling water to and from the cooling panels within the vessel through water inlet and outlet connections (42,43) distributed around the exterior of the vessel. Coolant flow system (62) includes large diameter water supply and return pipes (66,67) mounted on an upper part of the tower (61) to extend around the upper end of vessel (11), a first series of vertical dropper pipes (68) of relatively small diameter connected to the main water supply pipe 66 and extending downwardly to connections with the water inlet connectors for respecting cooling panels of the vessel and a second series of smaller diameter vertical pipes (69) connected at their upper ends to the main return pipe (67) and at their lower ends to undivided outlet connectors for the cooling panels in the vessel.

A method for manufacturing a cooling plate (10) for a metallurgical furnace comprising the steps of providing a slab (11) of metallic material, the slab (11) having a front face (14), an opposite rear face (16) and four side edges; and providing the slab (11) with at least one cooling channel (30) by drilling at least one blind borehole (40) into the slab (11), wherein the blind borehole (40) is drilled from a first edge (22) towards an opposite second edge (24). In accordance with an important aspect of the present invention, the method comprises the further steps of deforming the slab (11) in such a way that a first edge region (46) of the slab (11) is at least partially bent towards the rear face (16) of the slab (11); and machining excess material from the front and rear faces (14, 16) of the slab (11) to produce a cooling plate (10) having a panel-like body (12) wherein an opening to the cooling channel (30) is located in the rear face (16).
摘要:
A cooling plate for an iron and steelmaking furnace includes a copper cooling plate body having at least one cooling duct for a cooling medium extending essentially parallel with the back of the cooling plate body. The cooling plate body further includes a preformed, externally accessible recess into which the cooling duct opens. A connection piece is utilized as a cooling medium connection on the back of the cooling plate body, while a formed piece fitted within the externally accessible recess forms a deflection surface for the cooling medium flowing from the connection piece into the cooling duct, or from the cooling duct into the connection piece.

A cooling plate (1) made of copper or a copper alloy for blast furnaces has a plurality of bore holes (6) for accommodating a cooling medium. The bore holes (6) are connected to a cooling medium intake (12) and a cooling medium outlet via connecting pipes (9) that are welded onto the cold side of the plate (5). Connecting pipes (9), at their plate ends (14), are furnished with flanges (15) that are formed by being flanged open. These flanges (15) are set into recesses (17) in the cold side of the plate (5), and are welded at their circumference by V seams (19) to the cold side of the plate (5).

A cooled furnace wall comprises a furnace shell with an inner and an outer side and cooling plates lining the inner side of the furnace shell. Each of the cooling plates has a plate body and protruding connection pieces for supplying the cooling plate with a coolant. The furnace shell has connection openings therein for interconnecting the connection pieces of adjacent connection plates from the outer side of the furnace shell. At least one of the connection pieces is formed by a tube bend that protrudes from an edge face of the plate body and that has a connection end to extending through one of the connection openings in the furnace shell.
摘要:
The present invention relates to a cooling plate for use in the inner lining of metallurgical furnaces, especially smelting furnaces or shaft furnaces, and relates to a method for manufacturing a cooling plate. The cooling plate has a plate member, which is made of a copper material, and has integrated coolant channels. To manufacture the cooling plate, a raw ingot is provided, which is equipped with channels, and has a starting thickness that is greater than the final thickness of the plate member. The raw ingot is then deformed in a rolling step to reduce the starting thickness to the final thickness of the plate member and to deform the cross-sections of the channels. In this connection, the coolant channels obtain circularly oblong, final cross-sections.
