Description

Technical Field

[0001] The invention belongs to the technical field of smelting, and in particular relates to an integrated refining and synthesis device. Background Art

[0002] A refining furnace is a smelting equipment in the field of hot processing. It can "strip off" impurities and oxides from metal materials placed in the furnace. It is mostly used for final deoxidation in ferrous metallurgy, impurity removal of crude metals in non-ferrous metallurgy or steel metallurgy, and alloying smelting. At present, common refining furnaces include RH refining furnace (RH, i.e., steel liquid vacuum cycle degassing method), LF refining furnace (Ladle Furnace, ladle refining furnace), AOD refining furnace (argon oxygen decarburization furnace, argon oxygen refining method refining equipment), etc.

[0003] In the field of modern metallurgical technology, metal materials are first refined in a refining furnace and then transferred to a synthesis furnace for synthesis. Impurities are easily introduced during the material transfer process, affecting product quality. The workload is large, and the operation is cumbersome and unsafe. In addition, the smoke and exhaust gas generated by the existing refining and smelting equipment during the refining process are directly discharged into the atmosphere, which will cause pollution. The refining process requires artificial filling, but the manual on-site operation is very dangerous. After the refining is completed, the liquid metal in the furnace chamber of the refining furnace is naturally cooled, and the cooling speed is slow, which may cause changes in the metal component content during the period.

Figure 7 , Figure 8As shown, the inner slide rail 22 and the outer slide rail 23 are both fixed on the fixed base 21, and both preferably adopt double tracks, that is, the inner slide rail 22 and the outer slide rail 23 have two parallel tracks. The two tracks of the inner slide rail 22 are arranged between the two tracks of the outer track 22, and the inner track 22 and the outer track 23 are perpendicular to the axial direction of the main warehouse body 11. The lower end surface of the first slide seat 24A is slidably connected to the inner slide rail 22, the lower end surface of the second slide seat 24B is slidably connected to the outer slide rail 23, the upper end surface of the first slide seat 24A is flush with the upper end surface of the second slide seat 24B, and the first slide seat 24A and the second slide seat 24B are arranged opposite to each other, respectively at the two ends of the fixed base 21. In this embodiment, the heating surfaces of the first heating element 25A and the second heating element 25B are preferably set as curved surfaces.

The bottom end of the first heating element 25A is fixedly connected to the upper end surface of the first slide 24A, and the bottom end of the second heating element 25B is fixedly connected to the upper end surface of the second slide 24B. Figure 7 As shown, when the crucible bin 12 needs to be heated, that is, when the heating mechanism 2 is heating, the first slide 24A and the second slide 24B are relatively moved so that the first heating element 25A and the second heating element 25B can be surrounded to form a cylindrical heating structure adapted to the crucible bin 12, and the cylindrical heating structure is sleeved on the outside of the crucible bin 12, thereby improving the heating effect. In this embodiment, the first heat sink 26A and the second heat sink 26B are preferably configured in a plate shape, and the plate surface is parallel to the inner slide rail 22 and the outer slide rail 23. The first heat sink 26A and the second heat sink 26B are both provided with a structure that can accommodate a cooling medium, such as a flow guide pipe, which is used to pass the cooling medium. In this embodiment, the first heat sink 26A and the second heat sink 26B are preferably cooled by oil, that is, the cooling medium is oil, and the flow guide pipe is connected to the oil cooling device to input oil as the cooling medium. As shown Figure 8 As shown, when the crucible bin 12 needs to be cooled, that is, when the heating mechanism is not heating, the first slide 24A and the second slide 24B are moved back to back, so that the plate surface of the first heat sink 26A and the plate surface of the second heat sink 26B are opposite to the crucible bin 12, and the cooling medium is introduced to force the crucible bin to cool down, thereby greatly improving the cooling speed. Compared with traditional natural cooling, the cooling time is shortened, and the change of the metal component content during cooling can be reduced, thereby improving the smelting effect.

[0088] The workflow of the device in this embodiment includes:

[0089] Open the front door 13 of the bin, put the solid phase material (or liquid phase material) into the crucible 6, control the first feeding mechanism 3, use the claw 35 to grab the crucible 6 and drive it to move into the main bin body 11, then control the second feeding mechanism 4, use the clamping ring 404 on the hanging plant 403 at the bottom of the connecting rod 402 to clamp the crucible 6, and then transfer the crucible 6 to the crucible bin 12;

[0090] Close the front door of the chamber, evacuate the main container 1 through the vacuum port to provide the vacuum environment required for the refining and synthesis process, and selectively introduce inert gas into the main container 1 through the reserved port 114, turn on the heating mechanism 2 to heat the crucible chamber 12, perform refining and impurity removal, and activate the exhaust hood 142 to discharge the fume generated in the refining process to the tail gas treatment process;

[0091] After the refining and impurity removal process is completed, hydrogen and other gaseous materials are introduced into the crucible bin 12 through the rotating tube 401 to carry out a synthesis reaction, and stirring is carried out using the stirring wings 412 on the rotating tube 401;

[0092] After the reaction is completed, the first heat sink 26A and the second heat sink 26B are moved to a position opposite to the crucible bin 12, and cooling medium is introduced into the first heat sink 26A and the second heat sink 26B to forcefully cool the crucible bin 12. After that, the furnace is opened and the crucible 6 is taken out of the main container 1 using the feeding mechanism.

[0093] The beneficial effects of the refining and synthesis integrated device of this embodiment are as follows:

[0094] (1) It can be refined or synthesized to avoid the introduction of impurities due to material transfer during the metal smelting process and improve product quality.

[0095] (2) The smoke and tail gas generated during the refining process can be directly collected and introduced into the tail gas treatment process to avoid atmospheric pollution.

[0096] (3) The device has a simple structure and is easy to operate. It can use machinery to replace manual labor for operations such as feeding and stirring, which is safer.

[0097] (4) By providing the first heat sink and the second heat sink, the crucible bin can be forced to cool down, which can greatly increase the cooling speed and shorten the cooling time, thereby reducing the change in the metal component content that may be caused during the cooling period.
