Description

technical field [0001] The invention relates to an intelligently controlled feeding device for a horizontal continuous feeding electric arc furnace and a use method thereof, belonging to the technical field of electric arc smelting. Background technique [0002] At this stage, the development of the total amount of crude steel presents the characteristics of rapid outbreak and large scale. In the future, the recycling of scrap steel resources will also undergo a stage of rapid and large-scale growth, and there is a high probability that the rapid growth of scrap steel resources and the fluctuation or slow decline of the total amount of crude steel will superimpose Event, therefore, my country's scrap steel resources will become more abundant quickly. The development of my country's iron and steel industry has passed the period of scale expansion, and is currently in the stage of peak arc top area. According to the development law of international electric arc furnace steel, a...

Furthermore, the labor intensity of workers is very high, which is likely to cause waste and physical damage, and reduce production efficiency.

[0004] Chinese patent CN201310453087.3 discloses a complete set of equipment for an alloy feeding system after an electric furnace or an electric converter. The whole set of equipment has a compact structure, a small footprint, and a high degree of automation. However, when the material falls, it will cause direct impact on the lower device. Equipment is fragile

Patent CN201510877669.3 relates to a feeding device for steel electric furnace, which provides a device that can feed the electric furnace at any time, and the feeding is easy to control, but it does not have a weighing device, and cannot accurately feed the raw materials of the electric furnace

Patent CN201720412898.2 discloses a feeding trolley device for an electric furnace, which uses a feeding trolley and a vibrating conveyor to feed materials into the electric furnace, wherein the feeding trolley is used to carry and transfer the vibrating conveyor, and the vibrating conveyor carries the material and transfers the material It is sent into the electric furnace, but its degree of automation is low and the amount of materials added cannot be accurately controlled. It is necessary to manually determine the weight of the materials before loading them into the trolley, and the trolley will send them into the electric furnace
