[0026] Please refer to Figures 1-5As shown in the figure, the utility model relates to a magnesium pressing device for spheroidizing agent smelting, which includes a furnace body 1. A protective component 11 is arranged above the furnace body 1. The protective component 11 includes a cover plate 111. A fixing plate 112 is arranged above the cover plate 111. A plurality of stabilizing frames 22 are fixedly connected to the bottom of the fixing plate 112. The plurality of stabilizing frames 22 are arranged in a circumferential array. A plurality of fixing plates 23 are fixedly connected to the outside of the fixing plate 112. The plurality of fixing plates 23 are arranged in a circumferential array. A stabilizing block 235 is fixedly connected to the outside of the fixing plate 23. An arc-shaped groove is formed on the side of the stabilizing block 235 away from the fixing plate 23. A counterweight column 231 is in contact with the arc-shaped groove formed on the outside of the stabilizing block 235. Two elastic clamping blocks 232 are fixedly connected to both the left and right sides of the stabilizing block 235. A connecting plate 234 is fixedly connected to the outer surface of each two elastic clamping blocks 232. An arc-shaped inclined plate 233 is fixedly connected to the top of the upper elastic clamping block 232. By setting the protective component 11, specifically, a plurality of counterweight columns 231 are respectively inserted into a plurality of groups of elastic clamping blocks 232 to increase the weight of the cover plate 111. After the cover plate 111 seals the furnace body 1, the weight is increased by being pressed by a plurality of counterweight columns 231, thereby preventing the occurrence of furnace spraying, improving safety, and at the same time being able to avoid the dazzling white light from affecting the staff. A lifting ring 21 is fixedly connected to the top of the fixing plate 112. An insertion ring 113 is fixedly connected to the bottom of the cover plate 111. A fixing rod 114 is fixedly connected to the center of the bottom of the fixing plate 112. The bottom of the fixing rod 114 passes through the cover plate 111 and extends to the outside. The outer surface of the fixing rod 114 is fixedly connected to the inner wall of the cover plate 111. After the cover plate 111 is installed, the insertion ring 113 is inserted into the furnace body 1, which can improve the sealing effect and reduce the generation of gaps. One side of the stabilizing frame 22 close to the fixing rod 114 is fixedly connected to the surface of the fixing rod 114. A placement box 115 is fixedly connected to the bottom of the fixing rod 114. Both the fixing rod 114 and the placement box 115 are made of high-temperature alloy steel. The placement box 115 is used to place magnesium ingots. After the cover plate 111 is installed, the placement box 115 with magnesium ingots enters the furnace body 1. Three fixing blocks 12 are fixedly connected to the outer surface of the furnace body 1. Vertical plates 121 are fixedly connected to the tops of the three fixing blocks 12. The vertical plates 121 are arc-shaped. A guiding ring 122 is fixedly connected to the tops of the three vertical plates 121. By setting the guiding ring 122 and the vertical plates 121, specifically, when the cover plate 111 descends, the guiding ring 122 plays a guiding role for the cover plate 111, and the vertical plates 121 limit the cover plate 111, so that the cover plate 111 can descend in a straight line, thereby more quickly being inserted into the top of the furnace body 1. This method can avoid the situation that the cover plate 111 has not sealed the top of the furnace body 1 when the magnesium ingots react, and can enable the reaction and sealing to be carried out simultaneously. The guiding ring 122 is conical, with the upper part being wide and the lower part being narrow. The outer surface of the cover plate 111 is in contact with the inner side of the vertical plate 121. The bottom of the cover plate 111 is in contact with the top of the furnace body 1. The insertion ring 113 is inserted into the inner side of the furnace body 1. The guiding ring 122 is used to play a positioning role when the cover plate 111 is installed.The arc-shaped inclined plate 233 is arranged in an arc shape and inclined. The bottom of the fixed plate 23 is fixedly connected to the top of the cover plate 111. The bottom of the counterweight column 231 contacts the top of the cover plate 111. When the counterweight column 231 contacts the arc-shaped inclined plate 233, it will push the arc-shaped inclined plate 233, and then the arc-shaped inclined plate 233 will drive the elastic clamping block 232 to move together, facilitating the installation of the counterweight column 231.;

[0027] A specific application of this embodiment is:

[0028] During use, first place the magnesium ingot into the placement box 115, and then insert several counterweight columns 231 into several groups of elastic clamping blocks 232 respectively. Since the arc-shaped inclined plate 233 is arranged at the top of the elastic clamping block 232, when the counterweight column 231 contacts the arc-shaped inclined plate 233, it will push the arc-shaped inclined plate 233, and then the arc-shaped inclined plate 233 will drive the elastic clamping block 232 to move together. Under the action of the connecting plate 234, the upper and lower elastic clamping blocks 232 will move together, so that the counterweight column 231 can be smoothly inserted into the elastic clamping block 232. After the counterweight column 231 is inserted, it will enter the arc-shaped groove in the stabilizing block 235, making the placement of the counterweight column 231 more stable. At the same time, the elastic clamping block 232 will reset under the action of elasticity and clamp and fix the counterweight column 231. After the counterweight column 231 is placed, connect the hook of the electric hoist to the hanging ring 21, and then the fixed disk 112 can be lifted. At this time, the fixed disk 112 will drive the cover plate 111 to be lifted together through the fixed plate 23. After moving the cover plate 111 to the guide ring 122, lower the cover plate 111. The guide ring 122 plays a guiding role for the cover plate 111, and the vertical plate 121 limits the cover plate 111, so that the cover plate 111 can descend in a straight line, and thus can be inserted into the top of the furnace body 1 more quickly. At this time, the placement box 115 with the magnesium ingot enters the furnace body 1, and the insertion ring 113 is inserted into the furnace body 1. This method can prevent the cover plate 111 from not sealing the top of the furnace body 1 when the magnesium ingot reacts, enabling the reaction and sealing to be carried out simultaneously. At the same time, the cover plate 111 is pressed by multiple counterweight columns 231 to increase the weight, thereby preventing the occurrence of furnace explosion, improving safety, and at the same time avoiding the impact of the dazzling white light on the staff.
