摘要： The invention relates to a cooling element (1, 101) for cooling the walls of shaft furnaces. Said element comprises a hot side (Hs) which is directed towards the interior of the furnace, a cold side (Ks) which faces towards the shaft furnace wall and at least one coolant channel (2a-d; 102a-d, 202), each coolant channel (2a-d; 102a-d, 202) having pipe sections (7, 8; 107, 108, 228) for the entry and exit of coolant. The aim of the invention is to improve the production technique for an element of this type, whilst at the same time reducing the production costs. To achieve this, the cooling element (1, 101, 201) consists at least partially of aluminium or an aluminium alloy.

摘要： The invention relates to a stave for shaft kilns, especially blast furnaces, with a refractory lining. The stave comprises cooling channels which can be impinged upon with a coolant. At least the front facing the interior of the kiln consists of a rolled component that is provided with grooves for receiving refractory material and is preferably made of copper or a low-alloy copper alloy. The aim of the invention is to improve said stave in such a way that it can be easily produced and assembled using little material. The aim of the invention is also to provide a stave that provides higher cooling performance with lower coolant throughput, whereby the temperature rise of the stave is limited in such a way that the times of exposure are significantly longer. To this end, two trough-shaped rolled sections are welded together with the troughs thereof facing the exterior. Bores for receiving the ends of pipe connection pieces are inserted into the rear supplementary section. Said bores are welded-in. The free ends of the rolled steel sections are closed by means of caps.

摘要： A cooling system for a blast furnace includes a cooling circuit (10) closed by a return line (16) and at least one circulation pump (26, 26', 26'') for circulating cooling water through the closed cooling circuit. An emergency feed line (36) with an emergency feed valve (38), which opens in case of a power failure, is connected to the cooling circuit (10). An emergency overflow valve (68) is located at the highest point of the closed cooling circuit (10). This emergency overflow valve (68) opens in case of a power failure, so that the closed cooling circuit (10) becomes an open cooling circuit (10) with an atmospheric pressure discharge at its highest point. A pressure vessel (34), which is connected to the emergency feed line (36), contains a certain volume of emergency water which is pressurised by a gas, so that, in case of a power failure, an emergency water flow establishes through the open cooling circuit (10).

摘要： Wall structure for a metallurgical vessel at the location where the vessel wall, on the hot side, is in contact with liquid metal and/or liquid slag, in particular for the hearth of a shaft furnace, comprising a steel plate lining (2), inside which lining at least one layer of refractory brickwork (15, 16, 17) is arranged, the steel plate lining (2) being joined to the layer (layers) of brickwork by means of mortar joints (5) and/or ramming compound joints (5) to form a cohesive structure, characterized in that metal bars (11) which run in the circumferential direction inside the steel plate lining (2) and project into the wall are present, which bars are connected to the outer side of the steel plate lining by means of attachment means (20) running through the steel plate lining, each assembly comprising a metal bar (11) and its attachment means (20) and the steel plate lining (2) forming, in the vertical direction, a unit which is sufficiently elastic to maintain a surface-to-surface contact along horizontal surfaces between the metal bars (11) and bricks (15, 16, 17) during operation.

摘要： A cooling panel for a blast furnace includes at least one internal passageway for conducting a coolant media and is formed by a casting process including the provision of at least one internal core forming a passageway, the material of the core being removed after casting. This allows the internal passageways to be non-linear, as opposed to those formed by drilled internal bores as per existing copper stave panels. The cored cooling channels can also be non-circular in cross-section, a particularly preferred cross-section being trapezoidal as this presents a larger cooling surface than one with a circular cross-section. Thus, for the same cross-sectional area, the effective cooling surface area supplied by a stave according to the present invention can be greater than that for known copper staves. A trapezoidal cross-section also allows the cooling channel depth to be reduced, in turn reducing the stave body thickness and giving scope for further increases in furnace volume. The use of this arrangement further allows the placement of the coolant supply and drain pipes to match the positions of the pipework for conventional cast iron panels. Thus, the staves can be retro-fitted into existing furnaces which have previously employed iron staves, allowing restoration work to be undertaken mid-campaign without the need for furnace shell alterations or external pipework modification. It is preferred that the stave is cast of copper or a copper alloy, but the invention can be applied to the use of other materials.

摘要： Refractory wall structure for a furnace, in particular for a metallurgical furnace, such as for example a blast furnace with a high process temperature during operation, which wall structure is subjected to a high thermal loading, comprising a steel outer wall, a refractory lining consisting of one or more layers of a well heat- conducting material on the inside of the outer wall, and means for cooling the refractory wall structure, whereby the wall structure also comprises a permanent, well heat- conducting metallic filling in a gap in the refractory wall structure, which filling has been molten inside the gap and then after solidifying forms a low heat resistance across the gap.
