Example Embodiment
[0038] Example 1
[0039] Such as figure 1 As shown, the electric arc furnace of this embodiment includes a furnace tube 1, a furnace cover 2, a furnace tube protection frame 3, an electrode 4, a conductive cross arm 5, a silo 6, a material tube 7, a distributor 8, a cross arm support 9, and an electrode Lifting control device 10, power supply and transformation system (not shown), water cooling cable (not shown), cooling water system (not shown), and electric control room (not shown).
[0040] The furnace barrel 1 is set in the furnace barrel protection bracket 3. The furnace barrel 1 of this embodiment is placed on a trolley 12 running along the guide rail 11. The trolley 12 transports the furnace barrel 1 into the furnace barrel protection frame 3 or from The furnace barrel protection frame 3 is removed. The top of the furnace barrel protection bracket 3 is the operating platform 13. The furnace cover 2 is placed on the operating platform 13 and can cover the upper opening of t...
Example Embodiment
[0044] Example 2
[0045] Such as Picture 11 As shown, the difference between this embodiment and Embodiment 1 lies in the following: the discharging port of the inclined material distribution pipe 8-2 of this embodiment is arranged horizontally.
Example Embodiment
[0046] Example 3
[0047] Such as Picture 12 with Figure 13 As shown, the difference between this embodiment and Embodiment 2 lies in that: the graded cloth board 8-5 of this embodiment is a trapezoidal flat plate, and the graded cloth board 8-5 is arranged parallel to the vertical line.
