specific Embodiment approach 1

[0037] Combine below Figure 1-10 Describe this embodiment, the present invention relates to the technical field of steelmaking, more specifically a steelmaking system and method, including a steel heating device 1, a steel smelting device 2, a shielding stirring device 3, a stirring power device 4, a pressure relief balance The device 5, the extension bearing device 6, the additive storage member 7, the linkage displacement device 8 and the interval storage device 9 place the steel in the smelting chamber 2-1, and when the steel enters the smelting chamber 2-1, the smelting chamber 2-1 1 will become heavier, driving the pressurized circular plate 8-4 to move downward, the additive located in the storage barrel 7-1 will flow into the hovering barrel 9-2 through the connecting slide tube 7-5, and start the storage chamber 1- The electric arc furnace in 1 heats the steel. When the steel gradually softens, the motor 4-2 is started, and the gear II4-3 meshes with the two gears I3-...

specific Embodiment approach 2

[0040] Combine below Figure 1-10 Describe this embodiment. This embodiment will further explain Embodiment 1. The iron and steel heating device 1 includes a storage chamber 1-1, an inclined leg 1-2 and a limiting ring 1-3. The storage chamber 1-1 serves as The function of load-carrying connection, the inside of the storage chamber 1-1 is fixedly connected with an electric arc furnace, the electric arc furnace can generate an electrode arc, and when the electrode arc occurs, it will generate high temperature, which can melt steel, and the lower part of the storage chamber 1-1 is evenly fixed and connected Three inclined legs 1-2 are used to support and fix the whole device, and the upper part of the storage chamber 1-1 is fixedly connected with the limit ring 1-3, and the limit ring 1-3 is set There is a keyway, which is convenient to limit the melting chamber 2-1, so that the melting chamber 2-1 can only slide up and down.

specific Embodiment approach 3

[0042] Combine below Figure 1-10 Describe this embodiment, this embodiment will further explain the second embodiment, the iron and steel smelting device 2 includes a smelting chamber 2-1, an air intake pipe 2-2, a telescopic empty pipe 2-3, a spring I2-4, a limit The plate 2-5 and the liquid outlet pipe 2-6 place the steel in the melting chamber 2-1, and use the electrode arc generated by the electric arc furnace to heat the steel until it is liquefied. There is a key on the melting chamber 2-1, when the key slides After being connected in the keyway, the limit of the melting chamber 2-1 can be realized, so that the melting chamber 2-1 can only slide up and down, so as to realize the removal of the corresponding amount of additives, and the upper part of the melting chamber 2-1 is fixedly connected with the intake pipe 2 -2 and connected, the intake pipe 2-2 is connected with the oxygen generator, and the oxygen is discharged into the melting chamber 2-1 through the intake p...

Abstract

The invention relates to the technical field of steel making, in particular to a steel making system and method. The method comprises the following steps: step 1, putting steel into a smelting cavity to increase weight of the smelting cavity, driving a pressurizing circular plate to move downwards, enabling an additive in a storage barrel to flow into a suspending barrel through a communicating slide tube, and starting an electric-arc furnace in a storage cavity to melt; step 2, starting an electric motor when the steel is gradually softened, and driving two groups of stirring plates to stir through engaged transmission of a gear II and two gears II to increase smelting speed of steel, and injecting oxygen gas into the smelting cavity through a gas inlet tube at regular intervals during stirring; step 3, opening a valve when the temperature of the steel is high enough, introducing the additive in the suspending barrel into the smelting cavity through a circulating inclined tube to increase smelting speed of steel again; and step 4, after the steel is completely molten, opening a valve on a liquid outlet tube for discharging molten steel from the liquid outlet tube through a telescopic empty tube.

Description

technical field [0001] The invention relates to the technical field of steelmaking, more specifically to a steelmaking system and method. Background technique [0002] Steelmaking refers to controlling carbon content, eliminating harmful elements such as P, S, O, and N, retaining or increasing beneficial elements such as Si, Mn, Ni, and Cr, and adjusting the ratio of elements to obtain the best performance. The pig iron used for steelmaking is put into the steelmaking furnace and smelted according to a certain process to obtain steel. Steel products include steel ingots, continuous casting slabs and direct casting into various steel castings. Generally speaking, steel generally refers to steel rolled into various steel products. Steel belongs to ferrous metal but steel is not exactly equal to ferrous metal. However, in the existing technology, additives need to be manually added during the steelmaking process, and the quality of additives cannot be grasped. It is particul...
