Description

Technical Field

[0002] Rare earth magnesium ferrosilicon alloy refers to an alloy made of ferrosilicon, calcium, magnesium, rare earth, etc. through melting and configuration. It is a good spheroidizing agent with strong deoxidation and desulfurization effects. It is added as a spheroidizing agent in the production of ductile iron to change flake graphite into spheroidal graphite, which can significantly improve the strength of cast iron. It also has the effects of degassing, desulfurization and deoxidation. Its use in the metallurgical and casting industries is increasing. Among them, magnesium is the main spheroidizing element and has a direct impact on the spheroidization effect of graphite. Ferrosilicon, rare earth ore and magnesium are the main raw materials for the production of rare earth magnesium ferrosilicon alloy. The production of rare earth magnesium ferrosilicon alloy is carried out in a submerged arc furnace, which consumes a lot of electricity. It can also be produced in a medium frequency furnace.

The telescopic push rod 21 extends forward to drive the pushing piston 57 to push forward, thereby pushing the material stored in the storage bin 23 into the tilting furnace body 1, so that the device can continue the feeding process during operation.

[0026] like Figure 1-Figure 11As shown, an automatic turning furnace for producing rare earth silicon magnesium alloy is used for smelting and producing rare earth silicon magnesium alloy. Before use, the turning furnace body 1 is placed flat on the upper end of the movable frame 6 on the top of the supporting machine tool 5. The turning furnace body 1 can be fed through the storage bin 23. The raw materials are placed in the storage bin 23 from the feed port 22, and the two sets of horizontal slide rails 14 and the third motor 58 are started. The third motor 58 is used to drive the threaded rod 60 to rotate, so that the threaded rod 60 can drive the top support frame 17 to move horizontally through the mounting table 59, and the displacement structure of the horizontal slide rail 14 is used to adjust the position of the upper support frame 17, so that the horizontal slide rail 14 moves the storage bin 23 on the upper end of the support frame 17 to the rear end of the turning furnace body 1, thereby making the storage bin 23 is docked with the feed pipe opening 43, and the ejection cylinder 20 is started, so that the ejection cylinder 20 pushes the telescopic push rod 21 at the front end, thereby controlling the pushing piston 57 inside the storage bin 23 to push the raw materials through the telescopic push rod 21, so as to realize the feeding process of the tilting furnace body 1. After the feeding is completed, the rotating structure on the top of the natural gas tank 29 is used to rotate the gas supply connecting pipe 28, and the gas supply connecting pipe 28 drives the gas pipeline 26 connected to the outer wall to rotate, so as to dock the end pipe cover 24 with the unloading slot 35 at the front end of the tilting furnace body 1. After the docking is completed, the natural gas fuel can be continuously transported to the inside of the tilting furnace body 1 through the gas pipeline 26, and the metal raw materials in the furnace are melted by heating with natural gas. During the heating process, the ventilation branch pipe 25 It can be used to connect external pipelines and to fill oxygen at the same time to improve the melting effect. The furnace body can be turned over by the rotating structure during the melting process.
