Problems solved by technology

[0003] The existing Hu electric arc furnace mainly has the following technical problems in the use process. One is that the electric arc furnace is fixed and supported by a support device fixed on the outside of the furnace body during the dumping process. The support column is welded on the outside of the furnace body. When the support column is used for support, the strength of the support column is too large, which may easily lead to cracking at the connection between the support column and the furnace body or deformation of the support column. In addition, the rotation process of the electric arc furnace is unstable, which may easily cause molten steel to splash; But the moment the furnace cover is opened, the hot air in the furnace rushes out and rushes towards the operator, which will cause burns to the operator; third, when the furnace body is fed, the cold material is almost all piled up under the feed port, which is likely to cause a heating dead angle. When part of the coarse material falls into the metal liquid, it will splash high droplets. If these droplets splash out from the feeding port, it will cause personal injury

Embodiment 1

[0042] Embodiment 1 has introduced a kind of steelmaking equipment with scrap steel making steel, as Figure 1-3 As shown, it includes furnace body 1, condensed water inlet pipe 2, condensed water outlet pipe 3, heat dissipation coil 4, pouring nozzle 5, cold material inlet 6, cold material inlet cover 7, steelmaking equipment includes cold material Uniformly distributed components 10; the fixed plate on the upper half of the furnace body 1 is provided with a heat dissipation coil 4, and the heat dissipation coil 4 is connected with a condensate water inlet pipe 2 and a condensate water outlet pipe 3; the middle area of ​​the furnace body 1 is fixedly connected There is a pouring nozzle 5, and a cold material inlet 6 is provided in the middle area of ​​the furnace body 1, and the cold material inlet 6 is equipped with a cold material inlet cover 7; the condensed water inlet pipe 2 and the condensed water outlet pipe 3 180° apart;

[0043] Such as Figure 4-5 As shown, the fu...

Embodiment 2

[0051] Embodiment 2 is an improvement on the basis of Embodiment 1, as Figure 6-10 As shown, wherein, the opening assembly 9 includes a pair of fixed seats 901, a pair of fixed seats 902, a connecting rod 903, a connecting rod 904, a driving rod 905 and a handle 906; a pair of fixed seats 901 is fixedly connected to On the cold material inlet cover 7, a pair of fixed seats 901 are perpendicular to the cold material inlet cover 7; a pair of fixed seats 902 are fixedly connected to the side wall of the furnace body 1, and a pair of fixed seats 902 are perpendicular to the furnace body 1 side wall; a pair of fixed seats 902 is located directly above a pair of fixed seats 901; a pair of fixed seats 901 is fixedly connected with a fixed shaft 907, and the fixed sleeve on the fixed shaft 907 is provided with a connecting sleeve 908, The connection sleeve 908 is fixedly connected with the fixed shaft 1 907 by bolts; the fixed shaft 2 909 is rotatably connected to the pair of fixed s...

Embodiment 3

[0060] Embodiment 3 is an improvement on the basis of Embodiment 1, as image 3 As shown, a pair of arc-shaped support plates 8 are fixedly connected to the outside of the furnace body 1, and the pair of arc-shaped support plates 8 are symmetrically distributed about the pouring nozzle 5. The distance is greater than the length of the pouring spout 5. When the furnace body 1 is toppled over, a pair of arc-shaped support plates 8 are in direct contact with the ground, and the pouring spout 5 will not be in contact with the ground.

[0061] In this embodiment, when pouring molten steel, the pair of arc-shaped support plates 8 are always in contact with the ground during the rotation of the furnace body 1, and the furnace body 1 is always supported by the pair of arc-shaped support plates 8 during the rotation process, which can Reduce the support weight of the rotating shaft, the rotating shaft only needs to provide a large driving force at the beginning of the tilting stage, as...

Abstract

The invention provides a steelmaking equipment for making steel with scrap steel, which comprises a furnace body, a condensed water inlet pipe, a condensed water outlet pipe, a cooling coil, a pouring nozzle, a cold material inlet, a cold material inlet cover, an arc Support plate, cover opening assembly, and cold material uniform distribution assembly; the cold material uniform distribution assembly in the present invention distributes the added cold material to the bottom of the furnace body more evenly, avoiding the occurrence of four corners of heating, and the cold material uniform distribution assembly can distribute the coarse material The middle material is transported to a place far away from the cold material inlet and falls into the molten steel to avoid high-temperature liquid splashing from the cold material inlet; the design of the opening component can be opened from the side of the cold material outlet The cold material inlet cover, the moment the cover is opened, the operator can avoid the burning of the hot air gushing from the inside of the furnace and avoid burns; the design of a pair of arc-shaped support plates can effectively protect the support shaft and extend the support shaft The service life is longer, and it can ensure that the entire dumping process is stable without shaking, avoiding molten steel splashing, and improving operational safety.

Description
