Description

SUSPENSION SMELTING FURNACE Background of the invention
The invention relates to a suspension smelting furnace according to the preamble of claim 1 , for instance a flash smelting furnace.
In the steel structure of current suspension smelting furnaces (illustrated in Figures 1 and 2), the shaft structure 7 of the reaction shaft 1 and the shaft structure 7 of the uptake shaft 2 are supported by a separate so-called main support frame 3, which is supported by main support pillars 4. Said main support pillars 4 are based on the ground, i.e. on zero level 5 of the smelter, outside the concrete foundation 6 of the furnace itself, and they are very high, in a big furnace about 25 m. The main support pillars 4 also are very thick, particularly in earthquake areas, because they support very large loads.
In the steel structures of current suspension smelting furnaces (illustrated in Figures 1 and 2), the walls of the settler 8 of the suspension smelting furnace are supported by so-called buckstay beams 10, which rest on a concrete foundation 6 placed under the settler 8 of the suspension smelting furnace and are attached to the furnace bottom beamwork by a spring arrangement 11 comprising pull bars and springs. The settler 8 of the suspension smelting furnace is arranged in between the buckstay beams 10. The buckstay beams 10 move along with the thermal expansion motions of the bottom 9 of the settler 8 against the spring loads and thus cause a compression force that holds the bottom 9 of the settler 8 together. Here the term 'buckstay beam' refers to a vertical support beam, the purpose of which is to support or reinforce a structure, not especially to carry it.
Brief description of the invention
The object of the invention is to realize a suspension smelting furnace with a lighter structure, i.e. a structure containing less steel. The object of the invention is achieved by a suspension smelting furnace according to the independent claim 1.
Preferred embodiments of the invention are described in the dependent claims. The invention is based on carrying the shaft structure of the reaction shaft and/or the uptake shaft by means of buckstay beams provided for supporting the settler. The arrangement according to the invention makes both the support frame and the main support pillars supporting the support frame on the smelter zero level unnecessary. It has been estimated that in large suspension smelting furnaces, the arrangement according to the invention saves about 300 tons of steel, which corresponds to about 30% of the total steel quantity of the suspension smelting furnace.
List of drawings
A few preferred embodiments of the invention are described below with reference to the appended drawings, where
Figure 1 illustrates a prior art suspension smelting furnace, viewed in a partial cross-section,
Figure 2 illustrates a prior art suspension smelting furnace, viewed in a partial cross-section,
Figure 3 illustrates a preferred embodiment of a suspension smelting furnace according to the invention, viewed in a partial cross-section, and Figure 4 illustrates a preferred embodiment of a suspension smelting furnace according to the invention, viewed in a partial cross-section.
Detailed description of the invention
Figures 3 and 4 illustrate a preferred embodiment of a suspension smelting furnace according to the invention. An example of a suspension smelting furnace is a flash smelting furnace.
A suspension smelting furnace comprises a reaction shaft 1 for smelting concentrate (not illustrated). The reaction shaft 1 comprises a shaft structure 7. The reaction shaft 1 also comprises a concentrate feed arrangement (not illustrated) for feeding concentrate (not illustrated), such as a copper or nickel concentrate, into the reaction shaft 1.
In addition, the reaction shaft 1 comprises a flux feed arrangement (not illustrated) for feeding slag-forming agent (not illustrated), such as flux, into the reaction shaft 1. The reaction shaft 1 also comprises a reaction gas feed arrangement (not illustrated) for feeding reaction gas (not illustrated), such as a oxygen-enriched air, into the reaction shaft 1.
Moreover, the reaction shaft 1 comprises a burner (not illustrated) for burning reaction gas (not illustrated), concentrate and flux, so that the reaction gas, concentrate and flux react together forming a melt (not illustrated) on the bottom 9 of the settler 8 arranged at the lower end of the reaction shaft 1. The melt created on the bottom 9 of the settler 8 comprises two layers; on the bottom 9 of the settler 8, there is created a matte layer (not illustrated) or a blister copper layer (not illustrated), and on top of it a slag layer (not illustrated).
In addition, the suspension smelting furnace comprises an uptake shaft 2 arranged in the settler 8 for exhausting combustion gases (not illustrated) from the settler 8, and thus for exhausting combustion gases from the suspension smelting furnace. The uptake shaft 2 comprises a shaft structure 7.
The suspension smelting furnace also comprises a concrete foundation 6 provided underneath the suspension smelting furnace, which foundation is arranged at least partly above the ground level, i.e. above the smelter zero level 5, so that the top surface 15 of the concrete foundation 6 is located at a distance from the ground level, i.e. at the smelter zero level 5, and so that the suspension smelting furnace proper is located at a distance (for example at the distance of 8 meters) from the ground level, i.e. from the smelter zero level 5. Because the suspension smelting furnace, and thus also the bottom 9 of the settler 8 of the suspension smelting furnace, is located at a distance from the ground level, for example molten matte or blister copper and molten slag can be tapped from the settler 8 for example to a ladle (not illustrated), to an electric furnace (not illustrated) or to an anode furnace (not illustrated).
The settler 8 of the suspension smelting furnace rests on top of a concrete foundation 6 provided underneath the settler 8 . The settler 8 is arranged in between buckstay beams 10. In Figures 3 and 4, buckstay beams 10 are placed at all sides of the settler 8.
In between the buckstay beams 10 and the settler 8, there is arranged a spring arrangement 11 for allowing a motion between the buckstay beams 10 and the settler 8, for example owing to a thermal expansion of the settler 8.
The shaft structure 7 of the uptake shaft 2 and/or the reaction shaft 1 is carried by the buckstay beams 10 provided for supporting the settler 8.
The shaft structure 7 of both the uptake shaft 2 and the reaction shaft 1 is preferably, but not necessarily, carried by buckstay beams 10, as is illustrated in Figures 3 and 4.
The shaft structure 7 is preferably, but not necessarily, connected to the buckstay beams 10 in the area located between the center part and lower end of the shaft structure 7, as is illustrated in Figures 3 and 4.
In Figures 3 and 4, in between the upper end of the buckstay beams 10 and the shaft structure 7, there is provided a support arrangement 12 for supporting the shaft structure 7 at the upper end of the buckstay beams 10. In Figures 3 and 4, the shaft structure 7 is partly fitted in between the buckstay beams 10.
In Figure 3, in between two buckstay beams 10 located on opposite sides of the shaft structure 7, there is fitted a beam 13, against which the shaft structure 7 is supported, and by means of which or by intermediation of which the shaft structure 7 is carried by the buckstay beams 10. In Figure 4, at the upper end of the buckstay beams 10 located on the same side of the shaft structure 7, there also is fitted a beam 13, against which the shaft structure 7 is supported, and by means of which or by intermediation of which the shaft structure 7 is carried by the buckstay beams 10. In Figures 3 and 4, the beams 13 are connected at the upper end of the buckstay beams 10. In Figures 3 and 4, the shaft structure 7 is provided by supports 14 fastened thereto, which supports protrude out of the shaft structure 7. In Figures 3 and 4, the shaft structures 7 are supported by supports 14 against the beam 13.
In Figures 3 and 4, the beams 13 fitted at the upper end of the buckstay beams 10 constitute a framework (not marked by a reference number) for the shaft structure 7 of the reaction shaft 1 and for the shaft structure 7 of the uptake shaft 2, both comprising four beams 13. The shaft structure 7 of the reaction shaft 1 and respectively the shaft structure
7 of the uptake shaft 2 are supported against the framework by intermediation of supports
14 fastened to the shaft structure 7 of the reaction shaft 1 and respectively to the shaft structure 7 of the uptake shaft 2.
In Figures 3 and 4, the spring arrangement provided in between the 11 buckstay beams 10 and the settler 8 comprises compression springs.
In Figures 3 and 4, the buckstay beams 10 are connected rigidly, i.e. immovably, to the concrete foundation 6. It also is possible that the suspension smelting furnace comprises an arrangement that allows motion between at least one buckstay beam 10 and the concrete foundation 6.
For a man skilled in the art, it is obvious that along with the development of technology, the principal idea of the invention can be realized in many different ways. Hence the invention and its embodiments are not restricted to the above described examples, but they can vary within the scope of the appended claims.
