Embodiment 1

[0034] Such as figure 1 As shown, this embodiment provides a horizontal continuous feeding electric arc furnace scrap distributing device, including a feeding channel 1, a preheating channel 2 for preheating with flue gas, and a conveying roller table running through the feeding channel 1 and the preheating channel 2 3. It also includes a number of feeding bins arranged at intervals. Several feeding bins are located above the feeding channel 1, and the bottom is equipped with a blanking port; the volume types of scrap steel stored in several feeding bins are different, and along the feeding direction Decreases in turn, and a heating device for heating scrap steel is also provided in a part of the feeding bin at the starting end of the feeding direction.

[0035] When feeding, first turn on the heating device to preheat the scrap steel. After reaching the preheating temperature, the feeding bin at the end opens the discharge port, so that the scrap steel falls on the conveying ...

Embodiment 2

[0045] This embodiment provides a method for distributing scrap steel in an electric arc furnace with horizontal continuous feeding, which includes the following steps:

[0046] 1) Turn on the heating spray gun 7 to heat the heavy-duty steel scrap in the first feeding bin 4, and when the heating reaches the set temperature, open the blanking port so that the heavy-duty steel scrap falls on the conveying roller table 3, and continue feeding to form a heavy-duty steel scrap layer;

[0047] 2) When the heavy steel scrap is transported to the bottom of the second feeding bin 5, the discharge opening on the second feeding bin 5 is opened, so that the mixed steel scrap falls on the top of the heavy steel scrap layer 8, and the mixed steel scrap layer is formed by continuous feeding;

[0048] 3) When the heavy steel scrap and mixed steel scrap are transported to the bottom of the third feeding bin 6, the discharge opening on the third feeding bin 6 is opened, so that the light materia...

Abstract

The invention discloses a horizontal continuous feeding electric arc furnace scrap steel distributing device and a distributing method thereof, and relates to the technical field of metallurgical feeding equipment, including a feeding channel, a preheating channel, a conveying roller table and several feeding bins arranged at intervals. The top and bottom of the feeding channel are equipped with a blanking port; the volume types of scrap steel stored in several feeding bins are different, and they decrease sequentially along the feeding direction, and some feeding bins at the beginning of the feeding direction are also equipped with useful It is suitable for the heating device for heating scrap steel; the present invention preheats scrap steel in advance by arranging a plurality of feeding bins, and setting heating devices in these feeding bins, which greatly improves the preheating temperature of the area near the bottom of the scrap steel material layer, making the scrap steel The temperature distribution of the material layer is more uniform, which can improve the production efficiency. It also solves the problem of melting and adhesion of light material scrap steel on the conveying roller table during the horizontal continuous feeding electric arc furnace feeding process, ensuring the normal use of the conveying roller table.

Description

technical field [0001] The invention relates to the technical field of metallurgical feeding equipment, in particular to a horizontal continuous feeding electric arc furnace scrap distributing device and a distributing method thereof. Background technique [0002] In recent years, with the increasingly serious ecological and environmental problems, the country has become more and more stringent on environmental protection requirements in the industrial production process. As a "short process" process in the production of iron and steel industry, electric arc furnace has the advantages of small footprint and low production consumption. At the same time, scrap steel is the main raw material for electric arc furnace production, which is of great significance to resource recycling and environmental protection. [0003] The cover of the electric arc furnace is closed throughout the entire smelting process of the horizontal continuous feeding electric arc furnace. The high temper...
