Definitions
- the invention relates to a cooling element for industrial furnaces, which consists of a plurality of tubes running parallel to one another and is exposed in the wall and / or in the cover, preferably an arc furnace.
- a water-cooled plate for arc furnaces which is arranged in an arc furnace so that it forms part of the furnace wall.
- the plate has an outer surface exposed to the inside of the arc, which is provided with a plurality of ribs or other projections.
- the ribs or other projections serve as the core for the sprayed under the action of the arc, molten slag, which adheres to these and to the surface of the water-cooled plate due to the cooling effect, so that an increasingly thicker layer forms.
- this known, water-cooled plate has the major disadvantage that it or the like once in its manufacture by the welded-on ribs. is comparatively complex and, on the other hand, that during the welding of the ribs during operation thermal stresses occur which very easily lead to damage.
- the welded-on ribs result in increased heat absorption, which is undesirable.
- the invention has for its object to provide a cooling element of the type mentioned ' avoiding the aforementioned disadvantages, which is easy to manufacture and attach and has a long life and practically uniform heat load.
- this is achieved in that the adjacent tubes of the cooling element are arranged at a distance from one another. In this way it is achieved that the splashing liquid Slag is deposited in the gaps between the tubes and solidifies as a result of the cooling effect of the tubes, so that gradually an increasingly thick layer of slag forms, which adheres firmly to the tubes of the cooling element and ensures good thermal efficiency of the arc furnace.
- the mutually adjacent tubes of the cooling element are advantageously connected to one another by webs which are located on the sides of the tubes facing away from the furnace interior. These webs prevent the liquid sprayed slag from passing through the gap between the tubes, so that the slag inevitably settles in the gaps between the tubes.
- 1 denotes the mutually parallel tubes of the cooling element, which are each arranged at a distance from one another, so that 2 form between these gaps.
- the gap 2 between the individual pipes 1 ensures that the liquid slag sprayed inside the furnace can settle in the columns 2, first in its rear, expanding parts immediately in front of the webs 3. Gradually, always more spattered slag deposited so that the gaps 2 are filled with solidifying slag, a solid slag layer being formed on the sides of the pipes 1 facing the furnace interior. Due to the different cross-section of column 2, the slag layer that forms is firmly anchored.
- the anchoring of the slag layer is therefore not achieved by special measures, such as milling grooves, placing welding beads, profiles, etc., but by spacing the pipes to be connected.
- Each cooling element is provided with an inlet and an outlet for the coolant, for example water, flowing through the tubes 1, the individual tubes of a cooling element being able to be arranged one behind the other in terms of flow technology or else parallel to one another, specifically individually or in groups.
- the tubes of a cooling element can be arranged both vertically and horizontally.
- the above-described invention is preferably suitable for use in arc furnaces, but is not restricted to this, but can be used in general in industrial furnaces.
