Background
It is known that, because of the dissolution of gases such as hydrogen, nitrogen, oxygen, etc. and the oxidation of the surface of the alloy liquid, smelting and casting are carried out in the atmospheric environment, defects such as air holes, oxidation inclusions, etc. are easily formed in castings, and the quality of the castings is seriously damaged. In order to prevent molten metal from being oxidized, the traditional method is to add a flux to cover the surface of a molten pool in the smelting process, and deoxidize and remove slag in the later stage of smelting. However, these methods inevitably erode the furnace lining, shorten the service life of the crucible or the furnace lining, and may generate new nonmetallic inclusions while deoxidizing.
Inert gas shielded smelting is to cover the surface of a molten pool with inert gas, drive air above the molten pool and form an inert gas barrier to protect molten metal. The smelting is carried out under the protection of inert gas, flux covering and deoxidation are not needed in the smelting process, so that the casting defects of non-metal inclusions, gas, slag inclusion and the like are greatly reduced, and the defects of insufficient pouring, cold shut and the like are reduced along with the improvement of the purity and the improvement of the fluidity of molten metal, so that the method is favored by many precision casting manufacturers.
Inert gas protection smelting usually adopts a mode of blowing inert gas at the top of a furnace, the existing inert gas blowing device is complex in structure and is fixedly installed at a furnace mouth, and the device needs to be removed when feeding and discharging molten steel, so that the use is inconvenient.
