[0031] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0032] like Figure 1 and Figure 2 As shown, this embodiment provides a scrap steel workshop process layout structure of a horizontal continuous charging electric furnace, including:

[0033] The horizontal continuous charging electric furnace 1 comprises a horizontal continuous charging section 11, a preheating section 12 and an electric furnace body 13 which are sequentially connected along the length direction thereof;

[0034] A plurality of scrap steel storage areas 2 are distributed on both sides of the horizontal continuous feeding section 11;

[0035] The tunnel structure 3 is located on one side of the horizontal continuous feeding section 11, and the scrap steel piled in the scrap steel storage area 2 on the same side can surround the outer periphery of the tunnel structure 3;

[0036] The molten iron transport line 4 is arranged in the tunnel structure 3, and one end of the molten iron transport line 4 can extend outward to a position close to the electric furnace body 13; the molten iron transport line 4 is used for driving a molten iron tank car 41.

[0037] Therefore, the structural arrangement of this embodiment is simple and compact, and by setting up a tunnel structure 3 in the scrap steel storage area 2 for the molten iron transport line 4 to pass through, the molten iron transfer function in the scrap steel storage area 2 can be realized without affecting the storage and feeding of scrap steel, which is simple and reliable.

[0038] Specifically, the length directions of the tunnel structure 3 and the molten iron transport line 4 are parallel to the length direction of the horizontal continuous charging electric furnace 1 .

[0039] The process layout structure of the scrap steel workshop of the horizontal continuous charging electric furnace also includes a scrap steel transport channel 5 for driving a scrap steel transport vehicle 54; the scrap steel transport channel 5 includes a first longitudinal transport channel 51, a second longitudinal transport channel 52 and a transverse transport channel 53, and the first longitudinal transport channel 51 and the second longitudinal transport channel 52 are both connected to the transverse transport channel 53; the horizontal continuous charging section 11 is located between the first longitudinal transport channel 51 and the second longitudinal transport channel 52, and multiple scrap steel storage areas 2 are distributed in the area between the horizontal continuous charging section 11 and the first longitudinal transport channel 51 and the area between the horizontal continuous charging section 11 and the second longitudinal transport channel 52.

[0040] Generally, the length directions of the first longitudinal transport channel 51 and the second longitudinal transport channel 52 are parallel to the length direction of the horizontal continuous charging electric furnace 1 , and the length direction of the transverse transport channel 53 is perpendicular to the length direction of the horizontal continuous charging electric furnace 1 .

[0041] Of course, the scrap steel transport channel 5 may also be arranged in other ways as required, and this embodiment is only for illustration.

[0042] Furthermore, the scrap steel workshop process layout structure of the horizontal continuous charging electric furnace also includes at least one scrap steel span, a scrap steel preheating span 63 and an electric furnace span 64 arranged in sequence along the length direction of the horizontal continuous charging electric furnace 1; the horizontal continuous charging section 11, the first longitudinal transport channel 51, the second longitudinal transport channel 52, a plurality of scrap steel storage areas 2 and the tunnel structure 3 are located in the scrap steel span, the transverse transport channel 53 and the preheating section 12 are located in the scrap steel preheating span 63, the electric furnace body 13 is located in the electric furnace span 64, and the part of the molten iron transport line 4 extending out of the tunnel structure 3 and outward is located in the scrap steel preheating span 63 and the electric furnace span 64.

[0043] The number of the scrap steel spans is preferably two or three, and they are arranged at intervals along the length direction of the horizontal continuous charging electric furnace 1. For example, in this embodiment, there are two scrap steel spans, namely the first scrap steel span 61 and the second scrap steel span 62.

[0044] It can be understood that the entire scrap steel workshop process layout structure also includes multiple groups of column structures arranged at intervals along the length direction of the horizontal continuous charging electric furnace 1, each group of column structures includes multiple columns 7 arranged at intervals along the length direction perpendicular to the horizontal continuous charging electric furnace 1, and a crane beam is connected between two adjacent columns 7 in each group of column structures for the movement of the crane. The area between two adjacent groups of column structures constitutes the above-mentioned scrap steel span, scrap steel preheating span 63 or electric furnace span 64. The entire layout structure can also include a crane arranged in the scrap steel span to facilitate the transfer of scrap steel to the horizontal continuous charging section 11.

[0045] The above-mentioned horizontal continuous feeding section 11 is used to transport scrap steel to the electric furnace body 13. Multiple scrap steel storage areas 2 are located on both sides of the horizontal continuous feeding section 11. Scrap steel can be stored in the scrap steel storage area 2. The scrap steel can bury the tunnel structure 3 under the scrap steel pile, and the scrap steel is piled higher on both sides of the horizontal continuous feeding section 11 to reduce the lifting height of the crane; generally, the scrap steel piled on both sides of the horizontal continuous feeding section 11 is close to the height of the horizontal continuous feeding section 11, which is convenient for using an overhead crane to add the scrap steel into the horizontal continuous feeding section 11.

[0046] Taking two scrap steel spans as an example, the molten iron transport line 4 passes through the first scrap steel span 61, the second scrap steel span 62, the scrap steel preheating span 63 and the electric furnace span 64 in sequence. The molten iron transport line 4 is located in the tunnel structure 3, and the molten iron tank truck 41 equipped with a molten iron tank can run on the molten iron transport line 4. The molten iron tank truck 41 equipped with a molten iron tank passes through the tunnel structure 3 on the molten iron transport line 4 to transport the molten iron to the electric furnace span 64. The tunnel structure 3 surrounds the molten iron transport line 4, so that the molten iron transportation process is not affected by the lifting of scrap steel, and because the scrap steel pile is generally high, the tunnel structure 3 can be buried at the bottom of the scrap steel as a dead material layer, which does not affect the scrap steel storage.

[0047] The scrap steel transport channel 5 is located at the first scrap steel span 61, the second scrap steel span 62 and the scrap steel preheating span 63, and is mainly used as a passage for the scrap steel transport vehicle 54. The scrap steel transport vehicle 54 is mainly used to pass through the scrap steel transport channel 5 and transport the scrap steel to the scrap steel storage area 2.

[0048] The scrap steel transport channel 5 here can be an existing road, such as a cement road or an asphalt road, etc. The above-mentioned molten iron transport line 4 can be a track structure. In actual use, the scrap steel transport vehicle 54 and the molten iron tank vehicle 41 should pass through the position where the transverse transport channel 53 intersects with the molten iron transport line 4 to avoid interference.

[0049] Furthermore, the tunnel structure 3 may be a concrete structure, and its shape may be Figure 2 A rectangular tunnel is shown.

[0050] Reference Figure 1 An electric furnace steel tapping line 14 is provided on one side of the electric furnace body 13 , and the length direction of the electric furnace steel tapping line 14 is perpendicular to the length direction of the horizontal continuous charging electric furnace 1 .

[0051] According to the need of adding molten iron, the second end of the molten iron transport line 4 can be located on the same side of the electric furnace body 13 as the electric furnace steel tapping line 14, or the second end of the molten iron transport line 4 can also be located on both sides of the electric furnace body 13 respectively.

[0052] Furthermore, the scrap steel workshop process layout structure of the horizontal continuous charging electric furnace also includes a basic support platform 8, and the horizontal continuous charging electric furnace 1 is supported and installed on the basic support platform 8. The above-mentioned transverse transport channel 53 can pass through the basic support platform 8 to facilitate the passage of the scrap steel transport vehicle 54.

[0053] The above is only an illustrative embodiment of the utility model, and is not intended to limit the scope of the utility model. Any equivalent changes and modifications made by any technician in the field without departing from the concept and principle of the utility model should fall within the scope of protection of the utility model.
