Description

Technical Field

[0001] The invention relates to the technical field of metal smelting, in particular to a metal smelting device and a smelting method for grenade body materials. Background Art

[0002] An electric arc furnace is an electric furnace that uses the high temperature generated by the electrode arc to melt ores and metals. The slag discharge channel and the molten steel discharge channel in the traditional electric arc furnace are different and are relatively distributed on both sides of the furnace body. In this way, the furnace body swings to one side to discharge the molten steel, and then swings in the opposite direction to discharge the slag. The discharge occurs after the electrode leaves the furnace body. In order to prevent the temperature from changing, flame heating can be performed inside the electric arc furnace to prevent the molten steel and slag from becoming thick due to the temperature drop. If the molten steel and slag channels are integrated together, the driving energy consumption when the furnace body swings back and forth can be saved, and the discharge of slag can be accelerated, and the flame heating time can be reduced. In addition, there are many unstable factors in the swing of the furnace body containing high-temperature fluid. By reducing the swing, the occurrence of unstable factors can be reduced.

[0046] A method for metal smelting of grenade projectile material, comprising the following steps:

[0047] Step 1: pour the smelting raw materials into the furnace body 1, then control the furnace cover 9 to move horizontally to cover the furnace body 1, and then control the electrode 10 to be inserted into the furnace body 1 from top to bottom;

[0048] Step 2: an arc is generated between the energized electrode 10 and the metal material, and the high temperature of the arc is used to directly heat the raw material, so that molten steel with floating slag on the surface is generated in the spherical groove of the furnace body 1;

[0049] Step 3: Control the de-energized electrode 10 to rise and leave the furnace body 1, and then the furnace cover 9 is separated from the furnace body 1 by swinging and translation. Next, the furnace body 1 gradually swings and tilts, and the spherical semi-groove feed port blocked by the double-control door 3 is opened. The molten steel is discharged after passing through the discharge cavity 4 and the diverter 5 in sequence. The door opening space opened by the double-control door 3 is submerged in the molten steel, and the slag floating on the surface of the molten steel is intercepted by the double-control door 3.

[0050] Step 4: After the molten steel is discharged, the double-control door 3 is fully opened, the channel switching is completed in the diverter 5, the furnace body 1 continues to swing and tilt, and the slag fluid is discharged after passing through the discharge pipe cavity 4 and the diverter 5 in turn.

[0051] The worm 23 is connected to the driving mechanism in the prior art. The rotation of the worm 23 drives the driving plate gear 22 to rotate, and then the door shaft 16 is transmitted through the driving shaft 21, thereby causing Figure 5 The valve plate 14 in the furnace rises and falls. During the stage of molten steel discharge, the valve plate 14 does not rise completely, and part of the space in the channel between the valve plate 14 and the spherical semi-groove of the discharge convex body 2 is opened. The molten steel flows into the discharge pipe cavity 4 through this part of the space, and then flows down through the funnel pipe cavity 281 and is discharged. During the process, the channel controls the inclination degree of the furnace body 1 to control the molten steel to always submerge the channel below the middle part of the valve plate 14, so that the slag floating on the surface of the molten steel is intercepted by the valve plate 14.

[0052] After the molten steel is discharged, the worm 23 continues to rotate, and finally the valve plate 14 is completely lifted and opened, so that the slag fluid can flow into the discharge tube cavity 4, and the diverter 5 below the discharge tube cavity 4 completes the channel replacement. Specifically, the driving plate gear 22 rotates to drive the pressure plate gear 35, and then drives the double pressure plate 37 through the first rotating shaft 36. The rotation of the double pressure plate 37 in the molten steel discharge stage is always that the small semicircular plate presses the inclined plate on the double drive frame 39, and the double pressure plate 37 continues to rotate, and the double The large semicircular plate of the pressure plate 37 will rotate to compress the inclined plate of the dual-drive frame 39, so that in the stage of slag fluid discharge, the dual-drive frame 39 has completed swinging, and the swing of the dual-drive frame 39 will drive the double-headed prism 17 to descend, thereby driving the conversion shaft 24 to rotate, and then the conversion gear 25 rotates to drive the plate rack 27 to translate, and the plate rack 27 pulls the discharge block 28, and the coarse column tube cavity 282 on the discharge block 28 is connected to the discharge tube cavity 4, so that the slag fluid is discharged through the coarse column tube cavity 282.

[0053] The slag fluid is also heated by flames during the discharge stage to avoid the problem of cooling and thickening of the slag fluid caused by long-term lack of heat supply. Specifically, the dual-drive frame 39 swings and transmits the lead-out shaft 34, and then the protective shaft 32 rotates to drive the protective gear 30. The insulation plate 31 slides to expose the circular hole on the insulation folding plate 29, and the heat supplement flamethrower 6 sprays flames outwardly onto the discharged slag fluid. By adding heat, the slag fluid is prevented from becoming thick, and the slag fluid is prevented from adhering to the inner wall when passing through the discharge pipe cavity 4 and the thick column pipe cavity 282, thereby ensuring that the slag fluid can be discharged smoothly.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
